What To Try Next?

The slick cables, stronger springs, relocated adjuster, longer fenders, twisted pulley had  improved the braking, but it still wasn't anything that compared to the 105 side pulls on my wife's '88 Cannondale.  We discussed removing the V brakes and installing dual pivots, but sending the frame back to Green Gear to be refitted just didn't look like it would fit in the bicycle budget.
We discussed different V brake adapters.   Inline, bar mounted...All were expensive and bulky compared with the Travel Agents.  Maybe they would work better, or maybe they would just make our checking account lighter.
Then I caught sight of a full color add for a Burley Duet.  The bike had linear pull brakes and Shimano STI levers.  I pulled out my magnifying glass and I couldn't find V brake adapters anywhere on it!  This was worth investigating and I got right on it.
  • A quick trip to Burley's web site revealed that the bike was equipped with RSX levers and Tektro calipers (at least it was in 1999).
  • A slow trip to Tektro's (JavaScript infested) web site revealed that the brake they were using was probably a 917a short arm linear pull brake.
  • A phone call to Dave at Green Gear revealed that the 917A is used on the Burley tandem and the Green Gear Sat-R-Day.  They work with standard pull levers, but they offer very little tire clearance.  They had them in stock and could sell me some for $18 per wheel.

Unfortunately, Green Gear lost out on that sale.  While awaiting Dave's return call, I had jumped the gun and had already ordered two pairs from my LBS.  They arrived seven days later and I installed them 4 hours after that.

Tektro also now makes a 927a caliper which has a slightly different arm design.  I have bought a pair but have yet to install it on anything to see how it performs.  I have hopes that it will be a little stiffer than the 917a.
