Tektro USA/TRP is recalling about 2,000 Spyre and Spyre SLC dual-piston mechanical disc brake calipers because the brake cable actuator arm can over-rotate, dislocating parts, causing the brake calipers to fail.
Lack of brakes results in loss of control and a crash hazard, posing a risk of injury to the rider and others. Tektro USA/TRP has received one report of a brake caliper failing in this manner. There have been no reports of injuries or property damage.
The recalled products were sold as original and aftermarket equipment by bicycle shops nationwide and online at universalcycles.com, tektro-usa.com and trpbrakes.com from April 2013 to December 2013 for about $90 for the Spyre caliper (shown to the right) and about $110 for the Spyre SLC caliper. The recalled calipers, which were imported from Taiwan, were also sold as original equipment on bicycles manufactured or distributed by BTI, Diamond Back Bicycles, Giant Bicycles, Hans Johnson Co (HJC), Kona, Marin Bikes, Quality Bicycle Products, Raleigh America Inc. and Volagi Cycles. Both models were sold with 140 millimeter or 160 millimeter rotors
Spyre calipers have a black anodized caliper body and a silver actuator arm with “Spyre” on it. Spyre SLC calipers have a polished aluminum caliper body and a black composite actuator arm with “Spyre SLC” on it. Recalled calipers have a fastening screw with a hollow six-pointed star-shaped head with no markings on it and a 3-millimeter pad adjust screw on the outward side.
