I'd like to convert my Swift over to 451 sized wheels, but wasn't sure what spoke count I'd be safe with. I'm a tad over 6' 4" and weigh about 215 lbs. I was thinking of a 28 spoke count for the front, but not sure if I should go 32 or 36 spoke count for the back. I already have a set of Tektro long reach calipers, I just need to build up the wheels. Thanks in advance.
