Freehub replacement question
Picked up a almost mint set of Shimano Tricolor hubs for a 650b project I am doing this winter. The only problem is it is a 7 speed Uniglide and since those are like hens teeth I want to change the freehub to a Hyperglide 8 speed. My question is which freehub to buy? I would like to stay with Shimano. So a 105 or???
Your advice would be great!
