Is SunRace compatible with SRAM?

SunRace uses a 7075 alloy for the larger 42 and 50t chainrings, then moves to steel for the smaller teeth.

What size cassette do pros use?

Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
