Hi guys,
just finishing up with my build Its a waorksman and I put in a SBP jackshaft kit coupled to a shimano internal gear 8-speed hub. the whole system works great. The prolem is that ,even though i have a front drum brake, the roller brake that comes with the rear hub is insufficient to stop the bike.
i was told that i could not put caliper brakes on the worksman wheels. Plus i have fenders. are there any other options out there that I may be missing?
Thanks
