Last week I bought a pair of mechanical Shimano BR-CX77 disc brakes for my Bike Friday Pocket Rocket. A friend of mine was selling them cheaply since he had upgraded to hydro/mechanical brakes.
Later this month I’ll receive a new fork with IS disc tabs for my Bike Friday and will install one of these using the 160F post mount adapter. Tokyo Bike Friday dealer ehicle will be installing the fork and a new threadless headset for me, allowing me to convert my nearly 4 year old BF to disc brakes at the front. For now I won’t be changing the rear triangle and the rim brakes at the back, since most of my braking has always been on the front.
Another friend of mine is interested in picking up the rear brake for his bike (his fork and front hub don’t support discs). Thus we both get a bargain price upgrade out of this pair.
Depending on how I like the second hand CX77 in action, I may then buy a new pair for use with my Elephant Bikes National Forest Explorer (NFE).
Here is an IRD Alpina-D front derailleur (FD) for the NFE. I’ll use it with my Spa Cycles TD-2 touring crank. It’s very similar to older Ultegra FD’s and works well with smaller chain rings:
Finally here is one of the Compass Babyshoe Pass Extralight tires (650Bx42) that I’ve bought for the NFE. These should make for a cushy but fast ride. A friend of mine is using the 700Cx32 Stampede Pass tires and loves them.
