I’m still new to tandeming, my wife and I bought a new Trek T2000 a couple of months ago. I have never been happy with the Avid center pull brakes that came on the bike. I suppose my largest complaint has to do with the “mushy” feel of the rear brake. This complaint is of course in addition to an overall feeling that the bike has a total lack of braking power. My last posting on this forum was also related to my dissatisfaction with tandem brakes, as I was looking into disc brakes. However, at this time I’m not ready to spend the money experimenting with disc brake systems.
In the mean time, my ideas to help the mushy feel problem are to do the following:
Replace the brake cable housing with Odysey “compression-less” housing to eliminate housing compression. The Downhill mountain bikers use this cable on mechanical discs. The strands in this cable housing are not spiral wound, but are run linear like a shift cable. The housing is wrapped with Kevlar.
Eliminate cable stretch by sliding a length of brass tubing over the brake cable as it runs the length of the top tube. Silver soldering the ends of the tube to the cable. Although the cable has basically been bypassed with the "solid" tubing, it remains intact
I welcome your thoughts and comments.
