CMXBX Photo Thread

M5- You asked the question why does CMX do it this way... and I answered.

The Gates PolyChain Carbon (Toothed) design manual (17595) warns against using backside-idlers with their toothed belts because of the damage they can cause to the belts...and that inside idlers are optimal according to gates. Mark at CMX has worked in close association with the designers at Gates for more than 10 years... This is WHY he chose the system design he did as his experience leads him down this path.

This is WHY CMX uses this design... I've talked at length with Mark about this over the years.

This has no bearing on why anyone else would do it any other way as this is a CMX thread.


The Gates design manual
I do have one question on the belt drive. Why run the belt outwards with the cogs over a smooth pulley rather than inwards on the back of the belt. It would make a more compact chaincase or use a cogged gear on the tensioner?

M5... Backbending a belt is a "no no" according to gates.... that is why Mark builds his drive that way.

Hmmm. I'm not sure I'm buying that argument, the serpentine belt on my Duramax back bends all over the place. The Yeti kit does it backwards?

ya brah, where is ur bike?? (screech) I think I saw it (the bike) mounted in a press earlier? u might b a redneck if your kit is worth 10x your bike!!! (I'm a redneck and proud of it! btw) lol
 
I love the yellow on that kit mounted on that Husky! Wish I had that kit for my bike haha :smokin:

Oh well, I'm sticking with the old Timbersled kit for now.
I do have the Raptor X2 dual ski setup for my bike this year which I am anxious to try out though.
 
Screech, I saw your bike at Mark's shop today. Stopped in as my wife and I were in Clyde Park visiting her folks. Have been driving by the shop for 4 years but finally worked out that someone was there AND I had time to stop. Ha.

Fun seeing the stacks of CMXBK parts as they get kits prepped and shipped and talking bikes with Mark and Mike. Saw some great and detailed pics as well. I didn't take any.

Will be great to get some seat time on one this winter though might be kind of dangerous for my pocketbook as I really need to wait at least one more year to upgrade kits but then hopefully bike, too. Every time I throw a leg over these newer kits and newer bikes, I get lusty. Ha.
