Brake Technology

WHAT ABOUT AVID?

Santana has worked with the good folks at Avid for many years. Their powerful rim brakes are standard equipment on every tandem we sell. After Avid introduced an 8-inch disk brake, many tandem owners ( and a few builders ) attached this cheap single-bike component to their tandems. Because these brakes looked pretty cool, other builders ignored Avid ’ mho published warnings against installing this brake on a tandem. meanwhile, Santana had tested Avid ’ s mechanical disk against our tandem-specific brake protocol ( published and disseminated since 1998 ), and immediately agreed with Avid that their bracken was only adequate for singles. specifically, in repeated real-world testing not one Avid brake survived a 500-foot origin on our inadequate ( .7 nautical mile ) and exorbitant ( 15 % ) test course. even when upgraded with a 10-inch rotor, Avid ’ s most mighty cable-operated disk faded into ineffectiveness after good over half a mile. Further—after a backing brake was used to rein-in the runaway tandem—we found that the Avid ’ s fictile pad-adjustment knob and a non-replaceable internal nylon bushing had melted, which forestalled further use. While Santana continues to encourage our friends at Avid ( now owned by SRAM ) to produce a disk brake adequate for tandems, their “ Ball Bearing ” mechanical disk ( an effective brake for individual bikes ) is not a safe choice for tandems.

warn – While many builders and dealers have installed Avid ’ s disk brake on a tandem, this habit is not sanctioned or recommended by Avid, and voids the manufacturer ’ s waranty.WHAT ABOUT AVID ?
Santana has worked with the dear folks at Avid for many years. Their knock-down rim brakes are standard equipment on every tandem we sell. After Avid introduced an 8-inch disk brake, many tandem owners ( and a few builders ) attached this cheap single-bike part to their tandems. Because these brakes looked pretty cool, other builders ignored Avid ’ south published warnings against installing this brake on a tandem. meanwhile, Santana had tested Avid ’ s mechanical disk against our tandem-specific brake protocol ( published and disseminated since 1998 ), and immediately agreed with Avid that their brake was only adequate for singles. specifically, in repeated real-world testing not one Avid brake survived a 500-foot descent on our short ( .7 nautical mile ) and steep ( 15 % ) test course. even when upgraded with a 10-inch rotor, Avid ’ s most potent cable-operated disk faded into ineffectiveness after just over half a nautical mile. Further—after a backing brake was used to rein-in the fugitive tandem—we found that the Avid ’ s plastic pad-adjustment knob and a non-replaceable internal nylon bushing had melted, which forestalled further use. While Santana continues to encourage our friends at Avid ( nowadays owned by SRAM ) to produce a disk brake adequate for tandems, their “ Ball Bearing ” mechanical disk ( an effective brake for single bikes ) is not a safe choice for tandems.

WARNING – While many builders and dealers have installed Avid ’ s magnetic disk brake on a tandem, this use is not sanctioned or recommended by Avid, and voids the manufacturer ’ s waranty.
