I want to put some hookworms on my 2005 raleigh m80, but I don't know if they will fit on my current rims, how can I tell? Also, I am going to be using this bike mostly for commuting since I broke my trek elance, but I would like to try some "urban assault" as well, hence the hookworms. The stock manitou six fork does not seem good for either as it does not have much travel and no lockout. What would be a good fork for this? I have little money and am willing to purchase used.
