what size bike do you ride?
EDIT:
i also think theres a race this saturday...you should stop by belleville bike co-op...its the only bike shop downtown thats worth a damn. but they will know if theres a race going on and when it will be, if its "Beat the Main" its a day-time (usually) race that starts at the bottom of the island and goes to the top along St. Laurent.
1000 st antoine. #060 (in the basement)
