Video suggestion. I just unscrewed a few frozen bottom brackets. What I did was was use a vice.. It worked! Press the Bottom Bracket Removal Tool and the BB lightly while turning the vice and screw down the vice and then get whatever tools you need to turn the Bottom Bracket Removal Tool.. I used a giant pipe and Heavy-Duty Adjustable Straight Pipe wrench. The bigger the better.
I don't care if your videos are long or short...they are always interesting and informative material👍even if you run out of content or ideas...don't worry...chew on one of your tires for 30 minutes...I'd still be watching✌️
i cleaned my seatpost. its the right size but if i ever put grease on it slips down while riding no mater how tight i put the clamp. its an old bianchi doss xcl i bought it second hand and still came with the original 27.2 seatpost edit: thank you very much for the tips you've left behind. 🥰🥰 for this month im trying to save up for some fiber grip. i might also try changing my seat post and clamp. im trying not to invest in a new bike body because its the first thing my mother bought for me last year that was expensive. the first bike i built was about 6 usd for the rust frame and fork and i made a steel bike for around 50 usd. and the bianchi was bought by my mother a year later whuch she told me was about 200usd. im just making estimates because im from the Philippines.
@@hardware4computer ohhhh so is it possible that since its second hand the setpost may be more worn down than it should be? just curios and thank you for the tip 🥰
Could be you are using too much grease. Maybe you are overweight. Maybe the clamp is weak for the type of riding you are doing. Maybe clamp is damaged. Can be many things.
@@RJTheBikeGuy possible its my weight. im 80kg. i just do road riding the furst time i cleaned my bike i put thin grease around it but as im peddling even in flat road i felt that i sunk and after a few mins i noticed the seatpost slipped down. thank you sir for the tips 🥰
Caliper gauges are an excellent pieces of equipment. I think this video demonstrates a variation of the adage "measure twice, cut once". Once the correct-sized seatpost is fitted, don't forget to give it a little wiggle every few weeks thus preventing the post from getting stuck and then having the pleasure of removing it.
I had no idea there were even different sizes that close. Also very glad to have come across your channel and see you working on bikes that don't cost 5000 dollars, as it's actually relatable to what I have. None of the stuff many content creators make videos on looks like anything I've had on my bikes past or present, and it's hard learning everything from scratch.
For complete accuracy, a telescoping gauge that can reach down below any distorted ears and weld distortion are the most accurate way to measure...it's what machinists use for measuring ID.
I appreciate this man. I buy one of these things every 2-3 months because i live in a bad area and they always steal bike posts and seats even if the bike is locked. This is sadly a common occurrence for me
I always take the seat/seatpost out and take it with me. Then they think someone just took it and if you return and they are still poking at it then hit them with the seat end as the post makes a great handle.
Wish you released this video about a year ago. Bought an old Kona Kula as frame only, measured it with a ruler and checked the internet which said 27.0, bought a nice classic Shimano seatpost for about $40. Turns out the size is 27.2, so had to spend another $50 for a Ritchey one. Cheers RJ and I hope your back has fully recovered?
They are great but the battery ones drive me crazy. You don't use them enough and by the time you want them, they run out of life. The various calipers I have require different watch batteries so I finally ditch them for a good Vernier caliper. A more expense and slightly harder to read but worth the freedom.
Hi, came back to your videos for doing some maintenance on my 45+ y.o. bike. Sorry to see that you had an accident a couple years ago, fx of vertebrae are serious. I hope you have recovered and are not having too much pain after this. Your videos are always the best, you have a good ability for explaining bicycle repair for the "rest of us". Seriously thank you so much for doing your videos, you make "it" look easy and it gives us confidence to try. THANKS AGAIN
Always great, informative videos RJ. Lighting and sound is excellent too! I've had two bikes with seat posts that fit well but slip a little bit while riding. One is aluminum and the other is steel. Problems solved with park tools grease SAC-2 designed for carbon fiber frames apparently. Using a little of this grease and making sure the collars were tight, worked perfectly. If necessary, the seat posts were also easy to remove.
Hello RJ, I got a vintage Trek Multitrack 7300 Hybrid bike with a 135mm rear drop-out and I'm looking to upgrade the wheel-set with a modern one. Problem is most come in 130mm nowadays. Frame is Aluminum, so bending is not an option. Can you recommend any other solutions? Is there a wax to extend the axle? Thank you.
I love how you are still making content and helpful videos. I watched it all the way through even though I have already learned this skill because of how entertaining you videos usually are.
I have that seat post. Because I used to have that very same style and color of trek bike. I rode about 8,000 miles on it. I ride on average 8 to 15 miles everyday almost 365 days a year. Longest in a day was 135. I Kept the seat post to my old trek. But haven't come across another yet. Had to scrap the old bike it was just wore out beyond rehabilitation. Aluminum frame was just warped and cracked at a few weld spots. Because I'm short, I have to get those downhill/women's bicycle style of frame. I call it a Slant Frame. Good bike, I highly recommend them. If you do decent maintenance on them. Like I said...8,000 miles is a pretty good trial for an entry level bike. 🚲⛺🤸
Is the 31.6 mm the diameter of the seat post or the frame tube? Could you measure your seat post diameter with caliper and tell me? (I bought a seat post which is 27.1 mm in diameter instead of 27.2 mm and I want to know if it's normal, because it causes it to be loose in the frame tube.) Thank you.
do you have DIY way to make seat poat from scrap metal tube around the house? Need to make top smalled to received clamp. sometims need to make bottom tube wider for better fit.
Helo RJ i really need your help My bike is always slightly goes to right when im riding, is it the fork or the frame that not centered? please help me and give me some advice RJ Thank you
Hi, RJ. I have an old Dawes. Needs a bit of work (new wheels and some caliper brakes). Frame is good quality steel. Roughly, how much is it worth. I think the frame alone is worth something, right?
Is a .2 margin ok when choosing the seatpost? I need a black 26.6 seatpost, which has been incredibly hard to find, so I was thinking about using a 26.4 seatpost. Does anyone know if this .2mm size difference will make the seatpost too loose?
Nobody can answer that 100% as steel and aluminum seat tubes have different wall thicknesses. And even then some aluminum frames are a little bit thicker than some too. Then there is about 0.06 factory margin of error on lower/mid range frames and then if the seatpost is removed and replaced hundreds of times like mine were when i drove my bike everywhere and took my seat&post with me when locking it then you can have 0.1mm of wear after time. Thats why i always have beer can shims in my tool box. cheers and hopefully RJ the bike guy can explain it better.
I've looking for the seat post size on a beinaiqi cavalier but no luck I'm assuming it's a 28 because I just got a 30 and it was too big I just don't wanna go down a size too small
13" frame size is pretty small. So, a new teenager or smaller adult would be interested in this size of bike. Still waiting to see videos on those four auction bikes from a year ago. Best regards 👍
Bought a seat post from my local bike shop today. The owner told me about a customer whose solution to a tight fitting seat post was to hammer it in. It took 2 and a half hours to get it out again.
Never got clear about this. If 31.6 is nominal size, to obtain the clearance fit there should be difference between seat tube and seat post. Is seat tube expected to be larger (and how much), or seatpost should be smaller from nominal size?
You're right, it's nominal sizing. Alloy seatposts average about ~0.1mm undersize, and seat tubes, well truth is they vary wildly. A handbuilt boutique alloy frame can be reamed out true to size to eliminate any variances caused by fabrication, while a box store bike can be whatever the supplier sent over. Carbon frames use an inserted mandrel, so they can vary significantly. Chances are you'll get it to within a tenth of a popular size, and that's probably what it is (with some exceptions, like the old Reynolds frames that were 27.0 and not 27.2).
Hello i am hoping you will help me by replying so i have Shimano Tourney Sl-TX30 gear shifters and i want to replace them with the same model (because the old one is broken) can i change it without taking the cable out from the drealuer cuz i dont want to interfere with the settings can i change the shifters with the same model with the old cable like without taking the old cable out (it isnt really a old cable cuz i just bought the bike and it is in new condition)
Hi RJ. I have fitted gears to a cheap bike. The rear one works fine. But the problem is with the front derailleur. It won't shift to the bigger ring. I have tried with four different Shimano shifters. It's like all the shifter are working fine on Ist and second but while trying to shift to third the shifter is not getting locked means the shifter refuses to get on third. I have changed the cables. All shifters are new. I am only concerned about the shifter and couldn't understand why it's not locking at third. The local bike guy says the distance between frame and front chain ring is the issue as its a aftermarket fit. Please extend your expert advice.
Hi, RJ. I’ve been stalled with a building project. I have a frame that came to me with no bottom bracket, and I know it’s 68mm and English threaded. I have NO idea how to figure the spindle length I need. Everything I’ve found tells me to measure the existing spindle. What if I don’t have one? I’m building with a single speed coaster brake and single chainwheel, so it seems to me there ought to be a straightforward way to calculate this. Can you help? I can’t be the only one too dumb to figure it out! Thanks, from Kermit.
Wait a minute! Why can't I use my trusty ole' wooden school ruler with the metal edge on it? Spin it upside down to the millimeter side and just measure it and millimeters like I normally do to everything else I measure?
Hi RJ, love your videos! Good pace, Good shots, Just the right amount of detail but what I really love is your work on REAL bikes while other How To's are either very amateur or (majority) work on high-end new bikes which are outside of the reality of many riders/ DIYer's. Thank you!!!!! Some suggestions: 1-explain how to clean the outside wall of rims (where rim brakes rub) that are old and need more than just a good wipe with alcohol (they need steel wool or something like). I'm not talking about rusty rims just black brake junk and slight scoring/wear. 2-You like soaking in lacquer thinner but it stinks, gives some a headache and damages paint if splashed. Maybe a comparison of other good cleaners to soak in so we have choices (like your early rust dissolver comparisons). And last, of all, can you post the links to amazon where you get your bags of the two most common wheel ball bearings. I can't find the ones you seem to use. Thanks and keep up the GREAT work!
31.6mm and 27.2mm seem to be all that is currently (post 2000) in use, with few exceptions. Maybe a few 30.9 posts just to throw people off. Always good to measure though.
I bought an aluminum seatpost guage but a different 1 than the 1 RJ uses in this video. Mine's ~6 inches long with a concave cone on each end with increments marked, but super close together so it's REALLY Confusing to TELL WHICH Increment is WHICH! DON'T buy the one I bought! The 1 I bought is all over the place on Ebay & Amazon & it's likely made in China (no offense to anyone but China isn't exactly known for quality/precision engineering ... even their bioweapons fail to work properly). The top of seat tube MUST be PERFECT for the seat post guage 1 bought to work, & STILL it could be off +/- ~0.2mm! Could you show a link to the seatpost guage YOU used in this Video RJ? (another great video, & we miss you. You sound healthy & fit btw).
Search for "cyclo seatpost gauge", it's a bit pricy and made out of plastic but as you've mentioned the large sectors for each size are very helpful for getting a reliable readout even if dealing with a squished seat tube that has been spread back out or a similar situation.
Did you watch the video? There was no seat post when I got the bike. The point of this video is how to find the size of the seat post when you don't have the seat post!

Clean all the old grease out of seat tube and off post. Use light coating of grease on post. Maybe get a stronger clamp.

Once the correct-sized seatpost is fitted, don't forget to give it a little wiggle every few weeks thus preventing the post from getting stuck and then having the pleasure of removing it.

May be moot now, but you may be able to buy a longer axle and replace the old one. Then you would add spacers (keeping the hub centered of course)

You're right, it's nominal sizing. Alloy seatposts average about ~0.1mm undersize, and seat tubes, well truth is they vary wildly. A handbuilt boutique alloy frame can be reamed out true to size to eliminate any variances caused by fabrication, while a box store bike can be whatever the supplier sent over.

Hi pls make a video on front and back wheel not parallel
Instead of applying grease, is it not better to use some paper?
you buy and sell bike? and if yes you make good money at it?
“A hair of play”. Where people are divided. 😂
For example I would try a larger one 😅
Interesting🙏

Right
Would probably be easier to first measure the outise, and subtract the tube thicknessx x2
that is exactly the brand I hv
Just call CService with the make and model
i go by feel
Easiest thing is to Google the bikes model. Confirm with a measuring device.
Um, there's like these things called rulers or tape measures or if you want to get fancy, calipers.
