Does anyone know the part number for longer drive belts? I'm running a 178 with a belt wrap that's designed for a 65mm so I need a little more length until I get the 65mm up top.

Any suggestions would be appreciated.

 

So are you saying you need the same belt as the 65 or stock belt? Or, the belt for the 65 with the belt wrap?

 

The stock size belt is K081145. The next size longer belt is K081153.

 

thanks red dog. i just picked up that k081153, the next size is a k081177.

olddoc i have the lm21 belt wrap designed for 61-65mm pulley but i currently have a 178 crank and stock upper. 65 will come once i have my lines and afpr set up. with the 65 i may be able to fit the stock belt

 

I've REALLY got to find out what size belt I'm running on the aero blue with the 192 crank pulley.
One day it's bound to break!

 

combination belts and pulleys can be confusing. I just wanted to understand your set up before quoting a number. Glad it worked out. DJ.....I wouldn't have a clue, but I bet it was fun figuring it out the first time.
