Best Bottom Bracket for Modern Crank Upgrade
Hello everyone, not exactly C&V except for the frame. I tired the Clydesdale forum first, but got no response. I am upgrading my mountain bike components (Bridgestone BM-3) and looking at Shimano's 3x9 Alivio. However, they make two models of 3x9 cranks. One uses a square taper bottom bracket, the other uses outboard or through bottom brackets, not sure the exact terminology. I am pretty heavy rider, 250+, so is on of these technologies better for a heavy rider? My gut says the square taper is better, but that is without any technical knowledge of the two. So which is better for a heavy rider? If my current bottom bracket is the right length for the 9 speed square taper, I might just go that route, but if I have change it, this would be helpful. Note, I had to upgrade the rims a while back, so the rear hub can do 7-10 speed, so that won't be an issue.
Thanks in advance! Chris
