Blackspire Twinty 2X chainguide review£89.99

Chainguide without rollers

BikeRadar score4/5

The excellent Blackspire Twinty 2X chainguide combines secure chain management with quiet-running durability in a refreshingly easy-to-install unit.

Blackspire score points straight away for a full range of ISCG, ISCG 05, SRAM and standard BB mounts in 32-36T or 36-40T big ring sizes, plus red, blue, white or black colours. Included washers make spacing easy and the lower tensioning guide is a trough design, not so dependent on perfect alignment. 

A lack of rollers means nothing to squeal or jam, but the ‘proprietary polymer’ has proved impressively tough and mud-proof so far. Chain noise is a minimal mumble with no obvious drag through the pedals. 

It works with or without a bashguard, with only one chain loss incident so far, and the skid plate on the single-piece 6061 alloy frame shrugs off sumping incidents. The whole 164g unit is made in Canada, too, if that sort of thing interests you.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
