The product description does not list the size of the thread end. Upon receiving the product, I noticed the threads were not a standard air hose size. They are smaller. I have to find some sort of adapter to go from the Presta inflator valve to my air hose.
Easy install. Went from 170 to 165. So far so good. Can’t say I noticed anything dramatic with the 5mm difference.
Makes switching chainrings very easy… although you do need a specific tool for the job.
The new price for a replacement for my gen2 is silly. This one is better price and works, you just have to swap the bash guard and bumper at top. This is a better price and I also got a sale discount. much more reasonable. Thanks!
