Thanks for the freewheel info WJ, also that's a nice clean bike =D
Where did you get the replacement Kenda Kraze 20x3" from? I have looked around a bit and not found them. I like the tyre's large radius tread profile truncated for the smaller tyre, and have pulled lots of glass shrapnel up to 5mm deep (x10mm long) from the tread.
I need to grease the idler as it can clunk around at times of varied riding, but disappears with load off and on when on a steady straight.
I'm also debating hydraulic brakes, or just more pads for the BB5. I liked the Avid BB5 manual adjustment cable brake performance, and simplicity to tweak while on the road waiting at an intersection you may have just tested the brakes leading up to. Adjustable lever position "standard" with cables, but is a higher spec option for hydraulics. Nearing end of life on the original BB5 pads, the uneven wear and maxed out adjustment means braking strength has dropped off. I'm debating whether to switch to hydraulic like the Code 5 on my 2009 Norco, as I also need a disc front brake set for another bike. I need to put fluid in the front brake of that Code 5, so will do that first as it might help me decide against the hydraulic =P
