Genius, got in touch with praxis,they couldn't send to Canada, but they got in touch with their Canada office, 2 days later it's here! Fantastic service, not so from local bike shop , couldn't be bothered ...... Thank you , so far no chaindrops in 3 rides. Yeah!
Thanks a lot ,i got my fathom1 last month via Bikeleasing from the Company , one problems til now, the left crankarm is losen two times....have to have a look at it, cool bike anyway
Have logged around 2,000 miles on my Fathom 2. I'm only now beginning to experience the chain ring derailment dilemma as you mentioned. Another thing to note too is that since the angle between the top gear and the chain ring itself so large, it causes additional wear on the chain itself, leading to premature "chain stretch".
Hi, yes, it comes stock with 2.60 tires (mine is 27.5 inch). It may be able to fit slightly larger with some clearance at the frame and fork. And the fork has worked fine, just the dust cap broke!
As with your experience, the chainring problem didn’t show up until after 9 months of riding for me. Good on Praxis for owning up to the issue. It wasn’t even on my radar to reach out to them, and it’s very difficult to find a replacement ring without swapping cranksets, since you need a SRAM direct mount ring that has a Shimano tooth profile…Wolftooth makes one but it’s like $80. I got a OneUp switch system that essentially converted the direct mount to a 104bcd…hindsight I probably should have just replaced the crankset with an SLX unit, but inventory was nonexistent at the time.
Yes, I was very pleased with Praxis for helping out. I also had the same inventory issues which I why I ended up with the RaceFace replacement cranks but it would have saved me a lot of money if I just called Praxis first! Good luck
if the frame is Boost (148mm) wide in the rear axle you need to use a chainring with 3mm offset, if not boost (142mm) wide only, a chainring with 6mm offset is used...
I also reached out to Praxis and they sent me a 3mm offset chain ring ASAP. Funny how the bike shop had no clue what I was talking about when I asked about this issue. I only rode the bike 2 times after replacing the 3mm offset and since then I changed all the components to full XT. Even the wheel set. The XT wheels have a offset as well for the disk and rear cassette. Nice stuff.
bruh my bike shop when i bouight it years ago fixed it, but when i came in to get a new one a few weeks ago they sold me the same one that caused the original issues lool and then tried to gaslight me i walked out and now do all my own fixes
@@JosephDredd31 thanks you as well brother but yea i realized there just trying to sell me stuff not fix. these guys also put a new seatpost dropper on my bike without me asking or saying anyhting was wrong with it lol good tiding brother
I think it's an inherent problem with the 1x systems as the chain angle is so large now. But, for general fun mountain biking when you don't need the bigger rings for racing, the 1x set-ups are more convenient. 3mm hopefully is enough...I've know by next year!!
@Dr. Richard Mountain ND praxis got my email and sent me a 30t 3mm offset chainring for free. That should do the trick. I Also got a chain guide as well
I have just bought this bike to my son and on his first ride in the neighborhood the chain fell two times. Today I will call the shop and hopefully they will be able to resolve this. Since I am in EU, idk if I can “contact Praxis” about this.. if I would have to return the bike bcs of this it would be such a pitty… he really likes it
If it is a used bike, it could be that the Praxis front chainring is worn. Also, check to see if the clutch on the rear derailleur is engaged - if it's off, this will cause the chain to fall off often as well.
@@Dr.MountainND Hi, thanks for replying. No, its a brand new bike (although was sitting in the store for a while I guess since its 2022 model year). I will check this things, thnx
I Have a Giant Fathom of 2017 vintage - All the so-called experts and experienced riders praise and bitch about various bikes - The difference between a 1 and 2 model and different years etc. - Chaps it's the components that make the difference. My Fathom frame is no different from a fathom 2 to a fathom 1. - All manufacturers knock out bikes cheaper with cheaper components, wake up chaps! - I love the frame geometry etc - I upgraded to Shimano XT and a narrow wide tooth chain ring, never a chain drop! now I have an awesome bike! you get what you pay for!

Hi, What is the maximum chainring size I can put? I'm planning to put 34T, but I'm wondering if it is going to touch the frame.. Thanks
Oh, that might be too big...I cannot say for sure as I've kept the stock 30T.

Have you done anything about the problem since then?
Great video!
Hi Dr. , Can i know the full specs of your purchase raceface crank. is it 24mm spindle? By any chance you know the BB size? Thank you Sir!!
I'm so sorry, I'm not certain how to be accurate with the dimensions as the local bike shop ended up installing the new cranks...
does the Giant Fathom fit 2.6" wide tires?
also have you had any problems with the fork so far?

Tell me please. What is the frame size of your bike and what is your height?
Large Frame. I'm 183cm tall (Just over 6')
@@Dr.MountainND Will this size be comfortable for 180 cm, what do you think?
It should fit just fine but the best way is for you to test ride one if you can. I imagine the medium frame would fee quite cramped for you...
Get bike. Take off Praxis(hit) chainset. Put in bin. Fit Shimano👍
It's a great hardtail Giant bike.
I have the same bike. I'm going to call praxis and see what they will do. I have the problem as well. The 3mm offset makes a big difference i guess

Why are you torturing yourself? Just buy a Shimano crank. Their a bargain now.
the 2022 model has a 1x10 drivetrain, I wonder if that was used to change the chain ring issue?
I didn't realize that...could be?!
I have just bought this bike to my son and on his first ride in the neighborhood the chain fell two times. Today I will call the shop and hopefully they will be able to resolve this.

in the end it was just the clutch position. Great bike !
@@3rij794 Fantastic! I'm happy to hear your son now has a great bike to ride
Great bike Would buy again
What is the correct BB with of fathom?
Sorry Stephen, I wasn't able to find the box so I'm not exactly sure the correct width...
