I bought 3 Wolf-tooth and put them on DA cranks as 1X. They are nicely offset for the chain angle.
These are not on the cross bikes.

Thank you

The SRAM Force RD had narrow/wide pulleys. What is the advantage of that? They seemed to just offer more friction.

anyone see ellen noble dropped her chain on her sram 1x bike this past weekend?

Excuse me if it has already been said, but 2x works great if you have a mechanic looking after your bike constantly. Even on dirt and rough terrain.
For those of us doing our own wrenching (probably not as well) 1x is so much easier to maintain for racing.

slightly OT but what else is new...

I had 2X but wasn't using my big ring and so got rid of it so i wdn't cut myself on it.

I see the fast dudes using their big ring. but i spose many are 1x nowadays.

I did 1 race fine w 1X but the next race i dropped the chain twice -- ruining my race. Bad bad! I think my chain is too long. That's all I can think of. So... 1X ppl shd make sure length is correct. Make sure cage is pulled well forward when in first gear. I'll adjust and test...

Well the dude above you brought the thread back from the dead so...

I have a fair amount of chain drop on my '90's mountain bike, but nothing on my newer CX bike (knock on wood). To a large degree the derailer acts as a chain retentioner (which is why a lot of 1x setups put a chain retentioner in place of the derailer).


With a short cage rear, proper chain length, and correct derailer limits it shouldn't be an issue. Ya can always use a clutch rear derailer if you are worried.

That said, I'm in my small chain ring for CX races. My speed is typically in the 10-12mph range so I don't need a big ring for that. I do hit it hard when we jump onto the velodrome on the CX race, but that isn't much over 20mph. Any time I might be able to use a big chain ring in a CX race, I'm letting my heart rate relax before the next climb/run...
