Need some help with a brake upgrade. Current setup: Hardtail 29er, BB7's, XTish build level for XC racing. Geared up rider weight 175lb.
I've always liked my BB7's, but I have some cash right now and was thinking of going to hydro's. I've ridden many other bikes with XT, XTR, XX, Formula, etc. and I like the increased stopping power of the hydro systems.
My question is whether I would also save weight by going hydro? I have money for XT level brakes or the equivalent from another manufacturer. Here are my calculations:
BB7 329g for 160mm front setup with G2 rotor plus 75g for Speed Dial SL lever. @405g plus maybe 50ish for cables and housing(GORE) for 450ish or so.
XT calipers, hose, and levers list around 300g not including the rotor. I'd keep my G2's at 113G each. So total around 410g.
Doesn't seem like I'd save much weight at all with the setup. I'd like to save at least 100g or more for this brake swap. I can't afford the high end stuff like XX, XTR. Are my calculations correct? Any advice on a brake change that will give me good hydro's and some weight savings?
Thanks in advance for any insights.
