I am in need of a new wheel set for my 29'er, and wondering if 650B's are an option. My current bike handles more like a supertanker than a bike. Great for straight lines once up to speed, but if there is a corner, watch out... The 650's are supposed to more responsive than the 29er and roll better than the 26". Additionally my wife rides a 650B, so we would be able to reduce pare tubes and tires.
Bike has disc brakes so that is not a problem.
Apart from lower BB, hence increased risk of pedal strike, if I were to put 650's on my bike, what disadvantages would I have.
