Sram XX 10 speed Groupset
Sram XX 10speed Groupset
Lets start off with the crown jewel in the groupset the Cassette . Let’s see how it is made.
Cassette and Chain
The revolutionary machined design of the XX cassette uses the same gruelling manufacturing techniques that produced the PowerDome road cassette. With X-Dome, eight of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. It’s a process that takes nine hours per cassette! Optimized for use with any SRAM 10 speed chain, Recommended chain: PC 1090, PC 1090R

As for the front mech I do not know where to start I will find out as much as I can for you. Put it this way there are 38 different front mechs and right now we are trying o find out what frames are going to qualifies I think I will compile a list but any help with any of your frames speac please just contact me also if you would like me to find about your frame please just contact me here.
