10 speed Road 11-32 Shifting performance
Which 10 speed cassette would produce better shifting(Rival drivetrain):
Shimano XT 771 11-32 (dyna-sys)
SRAM PG-1070 11-32
I think the actual cogs have the same teeth and jumps.
And which chain?
I notice Scott uses Shimano cassettes on their high end road bikes.
You likely won't notice a difference. The biggest difference between cassettes is weight (and price of course). Buy the one that better fits your budget or weight goals. With chains, again you'll likely not notice a difference in performance. However, if you place on removing the chain for cleaning (as opposed to cleaning on the bike) you'll want to purchase a chain with a master link like SRAM, KMC, or Wipperman. Shimano using a non-removeable joining pin and breaking the chain requires installing a new pin (not a huge deal but more work than a master link).
