REFLECTOR: Main Tire Tubes

[Laurence Coen]

Brian,

Fixed gear=6.00-6, retract=15x6.00-6 tire size.

I assume that you are talking about the bolts that attach the axel/brake 
caliper to the gear leg.  Mine are standard AN hardware with friction nuts. 
The brake disk is attached to the wheel with cap screws (socket head).  In 
my install the bolt heads are on the inside of the gear leg and the nuts are 
against the caliper mount.  They can be turned around with the nuts against 
the gear leg but you still have a bolt retained with a friction nut and that 
should retain torque.
