Alright, so I'll plan on using a 140mm rear rotor paired with a BB7 MTN caliper.
I'll get a front 160mm IS adaptor, which should fit as a rear 140mm IS adaptor if I understand ?
Then for the rotor, I wanted to go with some lightweight ones like the Ashima Airotor or Alligator Wind Cutter or the KCNC Razor. After a bit of online reading I find out those rotor don't offer great wear life compared to "full" surface rotor type, and I found a deal for a new 140mm HS1 with bolts for $12. Seems legit but I'll double check before order.
Now is anyone tried those rotors in 140 with a BB7 and what's your opinion ? The lightweight rotors are around 62g while the HS1 is 76g.
