Does anyone know what size of bolts are used on Profile cranks? My 20" Monty/Alex/Profile arrived today… without crank arm bolts. I’m hoping to pick up something at the hardware store until I talk to unicycle.com.
Also, everything came to me unassembled. Is there any standard number of spacers between the hub/bearings and the cranks/bearings? I was just going to space out the bearing until the bearing caps clear the hub and put a spacer between the cranks and the bearings.
I recently disassembled my Profile setup to lube up with anti-seize. I have thin spacers and thick spacers and found that mine requires at least two thick spacers between the hub and bearing to give clearance between the outer hub shell and the edges of the main cap bearing holders. The frame forks on my Sem XL then need to flex outward a bit to meet up with the bearings.
George, what frame are you using? Did you make your own frame?? I’m planning on hooking up with you guys for the July 24, wednesday, of RAGBRAI. I still haven’t decided if I’m riding the whole day, since it’s a 69 mile day. I may just start later on in the route for the day. We’ll have to figure out a way to get together for that day. Maybe we could swap cell phone numbers, so we meet up. see ya…Joe (Mojoe) in North Iowa
That’s odd, on my profile with the same bearing holders all i need is a thick and a thin on the inside and a thick on the outside… except on the longer side which also has a cone washer on it… oh well, it works!
Same frame, Max? That somehow may make a difference. I tried a thick and a thin on the inside and ended up with contact between the hub and bearing holders. It was slight contact but enough to affect the wheel a bit, much like an overtightened bearing would affect the wheel’s spin.
