    New BB7 MTN S in 2014

    I see there will be a new version of Avids BB7 in 2014:

    BB7 MTN S Mechanical Disc Brake | SRAM

    I think it looks better - but does anybody know if there are funktional improvements/differences to the older BB7 (without "S")?

    The only changes I am seeing are the finish, provided rotors, organic pads (rather than metallic). Weight is for caliper only while the "regular" BB7 weight includes the rotor.

    I doubt the S is lighter, but it does cost $30-40 more, so it must be better

    Hope the old version has not been dropped.
    The trouble with common sense is it is no longer common

    Looks like the "S" is because it comes with "Stainless Steel Hardware"
    It also looks like they don't recommend it for certain types of riding with the stock rotors and pads that they supply with it.

    BB7 MTN S Mechanical Disc Brake | SRAM
    Organic Pads & HS1 rotor
    Intended Use: Cross Country, Trekking, Comfort, Mountain

    BB7 Mountain? Mechanical Disc Brake | SRAM
    Sintered Pads & G2 rotor
    Intended Use: XC/TRAIL/AM/FR/DH

    The new BB7 S has a listed weight of 197gm for the Caliper Only (this weight must be with the CPS hardware, the IS to PM adapter and IS mounting bolts too)

    Old BB7 = 155gm
    160mm front IS to PM adapter = 14gm
    CPS hardware = 21gm
    IS adapter bolts = 11gm

    Sintered pads = 24gm
    Organic pads = 23gm

    160mm HS1 rotor = 90gm
    160mm G2 rotor = 104gm

    The old BB7 has a listed weight of 329gm
    155gm caliper + 14gm adapter + 21gm CPS hardware + 11gm IS adapter bolts + 24gm pads + 104gm rotor = a total of 329gm
    * 6 rotor bolts weigh 14gm so it doesn't look like they're included in the weight.

    New BB7 S
    197gm caliper (with mounting parts) + 23gm pads + 90gm rotor = a total weight of 310gm
    * I'm only guessing that this would be the total weight of the new BB7 S with a rotor and pads.

    14gm rotor weight difference + 1gm pad weight difference = 4gm difference in the weight of the old BB7 caliper and the new BB7 S caliper.

    4gm = less then the weight of one IS adapter mounting bolt.

    The older silver Type N BBBD / BB7 from 2002 to 2007 was 13gm lighter then the newer dark grey/black BB7 from 2008 to present day.

    The old 2002/2007 BBDB/BB7 caliper would therefore be lighter then this new BB7 S caliper.

    At that're better off going Hydro. If you had BB7 before - this is close to a lateral move, at a higher cost.
