- In this video, I rescue a GT Backwoods and add a 7-speed wide range cassette to make it more functional without the need to upgrade to an 8-speed wheelset.
Thank you to Soma Fab Shop for sending me a cassette to make this video!

It's so awesome to see a great bike being brought back to life by a masterful restoration. Your restoration work is helping preserving the earths resources in contrast to rampant consumerism of buying everything new instead of repair and reuse. It's important to remember the better thing for the environment is not to buy the new "green" thing, but repair and reuse what we already created.
The triple triangle is just timeless. No other brand has such a single style along their range.

I'm often a purist about vintage bikes but I like what you've done with this one. I love old GTs!
I’ve been looking for ideas to omit the front derailleur and this is a good option.
I wish Shimano would take advantage of the CUES system and make an 8 or maybe 9 speed cassette for a 7 speed hub using 11 speed spacing. It would be a huge game changer!
Agreed!!
Actually they may already have (without mentioning it). Look at any photo of the rear of a cs-lg400-9 cassette - there is a spacer on the back. Remove that (likely have to grind out the 3 rivets [*]) and you should be good to go. [*]Sheldon Brown's website shows how to do this. Doing this is essentially Sheldon's 8 of 9 cassette setups.
I always lean on the cranks so it cannot roll, of that makes sense. The peddle hooks around the pole, pole rests on crank arm. Works on vertical ans horizontal like a bench just by rotating crank to correct position. Also...1x7 wide range has been my go to drivetrain for over a decade.
Great work. Amazing how great and reasonably modern it looks when you're done.
Nice ride thru on the end. That really helps put into perspective the size of the bike and how a rider looks. I subbed to your channel. Great content!
That cleaned up VERY nice and had some nice brakes and wheels. Looks fantastic!
Excellent result there. That bike looks great! 👍
Great job, Todd, gorgeous bike. I love the old GT's!
Oh man, I wish I would have seen this a week ago, that looks like the perfect cassette for what I want to do! I ended up just with a 12-32 7sp, because it was cheap and available, but now I’m going to have to order one of these 13-40 ones! Great video!
Beautiful bike, man!
Loved the wheelies🚴🏽♀🔥🔥🔥🔥🔥🔥🔥
Im surprised more people don't run 2x8 gearing. I've ran mine for two years so far and haven't seen any others. great for climbing. Great for speed.11-42, 24-36. My bike is still in the 24lb range, so weight isn't a issue.
Kind of depends on where you live. I went from old-old 3x9sp to 2x10sp and really, really wanted to like it. Problem is the trails where I live go from flat to quickly very steep or are rolling between very pitchy to a quick down hill, into another very pitchy climb. So I was constantly needing shifting both front and rear at the same time. As much as I *hate* the big gaps between each cog, 1x just lets me make the needed shifts a lot quicker. Problem is the manufactures are so hellbent on "range". 11-46T is fine for me. I'd love to go from 11-speed to 12-speed to get closer gaps in the cogs, like a 2x has -- but no.... lets waste that extra cog on an even larger cog than 46T that I don't need.
Those hubs are indeed awesome
I love old GT's too and I have 16" 1998 GT Tempest ( ball burnished, 6061 HT frame) with yellow and blue decals.
This is my BMX conversion set up:
Shimano XT rear derailleur, Deore 9 speed shifter, 1x9 set up, 11-34 teeth XT cassette, XT chain, RSP blue 34 tooth chainring paired with XT Hollowtech cranks, with yellow DMR v11 pedals. DMR saddle with navy fabric edge, DMR navy BMX grips with shallow flange, Haro F4 chrome BMX handlebars, GT BMX stem, DMR Trailblade 9 forks, DMR Moto R tyres paired with Mavic rims, Deore hubs, Avid V brakes, borrowed from my GT Tequesta, a black micro adjust with two bolts seatpost (non branded). The only brand new parts bought for this build were a Cane Creek headset, grips and pedals and cables, all other parts were bought used. It's light and looks great, and it brings a smile on my face every time I go out riding it!
Nice built👌
Very nice!
That’s good to know, thanks.
Excelente trabajo.
Terça gorda cedo assistindo suas "restomods" maravilha como sempre. Obrigado, bom trabalho.
It seems to be a good solution for someone with those specific needs. I have a 1X12, a 1X10, a 3X8 a 3X9 and don't have the need to convert. A fun project non the same. Regards 😊
I've been a fan of the 1 by set ups... Just think it cleans things up.
Nice, maybe a little more rise on the bars would make it even better, but thats an easy upgrade!
Still have a 7 speed cassette on my 98 Marin DH FRS. V light use and stored in a heated garage 19yrs before it came my way.
very cool parts washer!
I run a 3x6 with a customized cassette. Yes you heard me right a 6 speed cassette, from the factory (mongoose threshold) albeit the original freehub has since broken and been replaced by a 7 speed with extra spacers to allow for only 6 gears
I actually have a sister bike to this one. An LTS, black with red graphics. Looks very close to this. I went through the whole bike and went 1x with
a wolftooth front ring. Now 1x8. Looks really clean.
I'm doing an old rat Pro Flex right now. It is all there but rough. Freehub was gummed up so it wouldn't peddle. Took the rear wheel apart and found bad bearings and a pitted cone. Took the freehub apart and the bearings were rusted black. Found one NOS on ebay for $20. The front hub was better but needs new balls so all that slowed me down. It's 3x8. I will 1x it if the front derailleur gives me any grief.
I was looking at doing the same with a wide range 7 spd cassette off Amazon. I am using an old 6 spd thumb shifter switched to friction mode to work with the 7 spd Alivio derailleur. I also am using my old 12 spd crankset, TruVativ Descendant, with a nw 30t chainring. The Power Spline BB is to wide, so I shimmed the right pedal to help with the Q-factor. Everything works perfectly, but whenever I do get a wide range cassette and derailleur hanger extension, I may swap out the front chainring to a 32t with a 6mm offset and just shim the BB on the drive side to keep the chain line properly set.
Nice Job have done a few 1 by conversions!!! doing one similar late 90 mtb. 😀
1x7 is a many gears as most people need, and it greatly simplifies shifting for folks who want a non-complicated bike. I built up an '89 Centurion LeMans road bike frame with a 14-34 7-speed cassette. That let me use the old freewheel wheels. Works great, but you are right - you have to choose the right BB spindle length.
I concur.
I removed my 3 x 7 cheapo Tourney junk and replaced it with a 8 speed setup. Acera deraileur, 11 - 34 cassette, 32 single chainring. It has the entire range I need.
This bike was toast!
I put a 11-36 cassette on my bike all I had to do was get a long cage derailer.
I've wanted to do something like this with one of my bikes.. turning it into a 1x7 because I just use it for rides around the neighborhood. In my case, I have a retro-esque Tourney 7-speed thumb shifter 😁 I still like thumb shifters for their simplicity and the speed of shifting up and down the cassette
Im restoring a vintage 18 speed. Im thinking of buying a mega-range 6 speed freewheel. 14t-34t, instead of a 28t to climb mountains vs more gears new derailer n shifter🤔🍻
I love my old GTs doing a resto-mod on a 98 Arrowhead.
I made my own cassette from shimano 11-40 8speed, just missed the last cog. It works ok on my ghetto gravel bike.
correct video.
Nice job! I like seeing an electric buffer/polisher in use :)...I do not see that hardly ever on all the bike restore channels that I watch. @10:34 My main concern with you using a metal tool like that is bending the very thin metal. I just did that on my latest restoration and now I am stuck trying to find replacements which is very very difficult. I should have known better as I do have a blind hole bearing puller but decided to use a screwdriver instead.
This is the first time I ran across your channel and I really enjoyed this Build you really did a good job on this bike! I like the idea of the seven speed. The Sunrace nine speed derailer may work as a seven speed because the pull ratios, the same as Shimano, 2-1. if it does work it’s good for 11 to 50 teeth and it has a clutch. I do a lot of nine speed stuff on my channel
Great!! I will definitely look into that derailleur. That would be the icing in the cake with this setup! I'll have to check out your channel, too! Thanks!
Cool. This bike just need 2 more things: tubeless and a fork service. Optionally an spd pedal.
GT Hadley front hub….nice score
I’ve only done 1x9 in the past, which previously were 3x7 speed. I didn’t know wide range 7 speed cassette were available but now I do, will bear in mind for any new projects I have coming up! 👍
My 2010 Trek 3700 came with a wide range 7 speed freewheel. It has somewhere in the 50T tange for the climbing gear and it is lovely.
@DePuesshop , I really, really don't understand keeping this bike 7-speed given you bought a new shifter and cassette. That front GT hub is beautiful and had a decent Mavic double-wall rim on it. That rear hub was a bottom end Shimano and a non-matching rim, to the front, that looked to be single wall. If the rear wheel matched the front I'd understand staying 7 speeds. Surely you have a decent 8/9/10-speed 26" double-wall rim wheel in your parts bin. Or, you could find a used on for $20. An 8-speed shifter and 8-speed cassette would likely have been about the same cost as the 7sp parts.
I see your point. I would rather have gone with something in 8 speed and up, but I wanted to show how to make a wide range 7 speed possible. Some folks would like to stay with the wheel/hub they have, and this is how to get a wide range with 7 speeds.
smart to run the chainring flipped to hide the ugly graphics! so simple and it never crossed my mind
Agreed!! I can't stand all those graphics on the chainrings.
Its offensive how bad that bike was to begin with. But we get great deals and projects with those.
Reminds me almost of both my mongoose tyax super and the specialized sworks m2 stumpjumper when i got them.
I use 3x7 mostly even when I 27.5 disc swapped.. they have better wheelspacing on the narrower cassette
Shimano does make a rear derailleur to accommodate a wide range 7 speed cassette. I'm currently using one on my old mountain bike and it works great.
What model is that derailleur?
The Acera rear derailleur. 40t max and works with 1x, 2x, 3x. It works with 42t as well.
@@DePuesshop it's the Acera M3020 with a total capacity of 45T, my rear cassette is 13 -42t. I bought mine from Riverdale Bicycle Works. They also have some wide range 7 speeds cassettes.
Go Green!!!
I’m in the middle of restoring a GT Ricochet! Love seeing this!
Go White!!
Do you have a target budget on what you want to spend on each of your rebuilds? How do you estimate on what a bike is worth before you consider a restoration?
@dm7646 That's a great question! I usually try to get an image in my head what I want the bike to be when I'm done, and then I try to get an idea of what someone might pay for it. Then, I do some research online for the parts, and look through what I have in the parts bin to see what it will cost me. Sometimes I get out of control and sometimes I do much better than I thought. I should do a video on the process.
That is an awesome build. The GT Hubs are spectacular.
What brand or model headset press are you using?
It's a cheap one I found on Amazon. I am not in love with it. It's kinda klunky and sometimes I just prefer my threaded rod contraption I use on other builds.
Bike was neglected and dying a slow death but hey! look at it now. Definitely worth bringing this bike back to life. Great job!
I still don't see the advantage of going 1x on a bike like this, I would have kept the 3x7 for an even wider range combined with smaller jumps from gear to gear.
Great build, loved the video! My next bike to build up is a GT ricochet so pretty simmilar. Do you also have a link to the derailleur adapter?
Cheers!

I feel bad selling my 90s Pro Flex. 😢
So glad I stumbled across this video. Trying to turn a Trek Antelope and Specialized Hard Rock into single speeds but have been pulling my hair out sourcing used 26 inch wheels with freehubs that will fit an 8/9/10 cassette. The Soma cassette is a huge game changer for me, I can't thank you enough! I did have a question for you about the bottom bracket though. Can you tell me the size of the BB you installed on your bike? I have a Shimano BB-UN300 at 127mm for a triple chain ring and am wondering if I can use that for the 1 x setup or if I need to get myself a narrower BB. Thanks so much for helping me make my old bikes great again!
The BB width really depends on the crankset you are using. All the cranksets are different. It's a trial and error. With this bike, I had to even use a spacer to get the chainline right.
@@DePuesshop Thanks for all the info. This wide range cassette is going to make my projects a LOT easier. I had no idea something like this even existed.
Websearch Sheldon Brown's "8 of 9" for his "k7.html" webpage. That's how you can get 8 or 9 speeds on the rear with a 7sp freehub body.
Your restoration came out awesome!!!! I have my 1997 gt Ricochet that I bought new & would like to put the 1x7 on it. Do you remember the mm you had to use for the bottom bracket?
Sorry, I don't. Honestly, getting the BB width correct on a 1x conversion is one of the hardest part. It all depends on the cranks you use. One crank will work with one BB and a different crank won't.
Ok thanks, I'll just wait on my chain ring to arrive so I can size it up to what I have.
Pedal backward on the 40t does the chain fall off? Did the shifting improve after tuning?
Shifts great, and it stays on the 40T when pedaling backward. It's nice and quiet.
Are those new cranks you put on there? If so, what kind are they?
Yes, they are Sugino cranks. The other ones didn't have the right bolt pattern for the chainring I had.
Why'd you put a new saddle on? That first one was just fine! 😀
🤣
the old Gt frames are nice for being different...do they come in different materials or they are all the same?
They come in both aluminum and steel.
So would my old Alivio 7 speed shifter for my 21 speed MTB move the chain the right amount for those cogs?
Yes, the only reason I got a new shifter on mine was because something tried to eat it!
what kind of bike hanger r u using?
amzn.to/3I5dRAx
What size chainring did you use?
This build has a 36T on it.
fis isto na minha caloi vulcan do brasil fico top
instead of using a space on the drive side you could have just mounted the single chainring in the outer position. That is how most fixed gear and single speeds are setup.
I tried that, and then the crank arm got too close to the frame. It was a weird combination of spacing.
Triple triangle sets GT apart from all other brands. It's timeless.
I want a wide range cassete but i'm afraid of extenders. i think they are easy to bend.
I haven't had any trouble with derailleur extenders bending.
hello around 11:00 do you put the same balls back in?
Normally, I put the same balls back in, but the ones in this hub weren't in the best shape. Luckily, I am a pack rat and had some of the correct size to replace them.
@@DePuesshop Thanks + great jobs on all your bikes. Would be interested in a shop tour too!
Why is this cassette an improvement? A range of 3.08:1 versus 4.7:1(13-32x22-42 assumed). What's your bottom gear again? Not 17.9? Or even close?
It's a great solution to get more range for a 1x setup. For those of you who love the 3x setup, you will always be better on range.
What derailleur did you use
8 speed Shimano XT rear derailleur.
@@DePuesshop are you using a short cage or a long cage, and are you using an 8sp chain
I’ve been skipping through the video so I might have missed it, how many teeth for your front chain ring?
I no longer have the bike to check. I think it was around a 34t.
@@DePuesshopthank you, love the video as well. Very informative as I’m learning to work on bikes myself.
Were those dog bites out of the seat and parts when you originally received the bike?
Yes!! That's exactly how I bought it. It apparently lost a fight to some critters!!
I had a dog who did that to one of my bikes lol@@DePuesshop
The bike frame was designed for someone 9 inches shorter than him.
1x7, very limited range and good luck finding a the right gear for training 🤔
11-42t...
Does anyone have a CUES 9-speed cassette that they can verify this with? The rear photos of the rear of a cs-lg400-9 cassette shows what looks like a spacer on the back (which also matches how I would understand Shimano puts 9-speeds in 11sp spacing on the freehub body. Remove that (likely have to grind out the 3 rivets [*]) and you should be good to go for a 7-speed body. [*]Sheldon Brown's website shows how to do this. Doing this is essentially Sheldon's 8 of 9 cassette setups.
The CUES uses a 1 to 1 pull ratio, which is not compatible with the older shifter pull ratio, so you can't get a 7 speed shifter to "talk" to the CUES cassette.
@@DePuesshop Yes, I know CUES has a roughtly 1:1 pull ratio (not the same roughly 1:1 as SRAM nor Advent nor Dyna-Sys). The question is can you use the CUES eco system on a 7-speed freehub body. That was what was begged for below in the other comments. Thus the Sheldon Brown 8 of 9 setup for CUES 9-speed shifter + cassette + any CUES RD.
The jumps are too big TBH. Would rather 7x2.
That's not an optimal setup. You sacrifice fast gear and climbing gear. A more optimal 7 speed setup would be an 11-46t 7 speed cassette paired with a 36 or 38t chainring.
No one makes a 7 speed 11-46t cassette unless you custom make your own by tinkering.
The company I got this from has a 11-42T 7-speed. That would be as good as it gets.
The cogs and spacers are loose, you can slide any gears you want on but shifting those big jumps might smash the jockey wheel into the next cog
i can see why you got your seat up high cause you got a long legs
Yep, sadly, that bike is a bit too small for me...
Were you riding it in Afghanistan?
Bike size too small 😂😂😂
Yep!! That's a good thing. Otherwise, I may wanna keep it!
I love the vintage bikes. Just cant do the 3x or the old narrow handlebar set ups. Cant believe how bad they were back then. 😂
