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!

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...

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".

Have you done anything about the problem since then?

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.

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.

@Dr.MountainND Жыл бұрын

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

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

@Dr.MountainND 2 ай бұрын

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.

@Develoquent Жыл бұрын

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

@Dr.MountainND Жыл бұрын

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!!

@Develoquent Жыл бұрын

@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

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...

does the Giant Fathom fit 2.6" wide tires? also have you had any problems with the fork so far?

@Dr.MountainND Жыл бұрын

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!
