Genetic chain tensioner review

All singlespeed and fixed wheel bikes will at some point suffer from the rear wheel creeping forwards, slackening the chain tension.

The simplest way to solve this is with chain tensioners: slot them over the axle and use the Allen head bolts to pull the wheel back equally and straight (and keep it there).

Genetic’s Track Chain Tensioners are the most ‘bling’ we’ve seen, available in gold, black, blue, red and white (£2 extra), and they work.
