Defective Freehub

I had a freehub failure after a few hundred kilometers of use. Unfortunately the bicycle was out of warranty and I had to purchase a replacement hub. The failure was that internal ratchet ring had lost it's bond with the hub and was slipping. Peddling barely moved the bicycle forward. Bitrix support was fabulous. Not only did they help diagnose and offer replacement parts but they overcame a big shipping problem delivering to a Greek island. My bike would be sitting DOA without their help and support.

No show

I was informed after placing the order with a support person that the tire was no longer in stock. So, I went elsewhere to find replacement tires.

Amazing bike and the Biktrix team are excellent at communication !

Embarrassing to say that during the minor basic assembly after recieving the bike. I popped the inner tube by not tucking it in properly before inflating :) So it took me a while to get a new tube. Finally rode my bike yesterday...Wow !!!

This is a bit off the subject. But I’ve made a request several days ago and haven’t got any response. My ultra FS is in the shop repierce that the axle might be broken the gears turn but the wheel doesn’t. Do you want to shop said perhaps it has something to do with the software? If you actually broken, it seems like it could be a warranty issue? Please advise feel

Still a Fat tire wheelset, not a true MTB wheel as width is 60mm

Still, 26x4.00 are not for me or my riding style. These wheels, although still "fat", can accomodate 2.8 DH tires with good knobs for cornering, tracking, and more surgical handling. I have Maxxis DHR and DHF and they rock on these wheels. The 26 will be saved for a snowy day, the 27.5 are my go to wheels.

27.5x3 Wheelset

Bought 2nd wheelset because I was curious on how it would change my ride. 27.5 rear install went well, will be able to switch back to 26x4 no problem. Also trying 27.5 on front 26 on rear setup.
