Here's a bonus video to accompany the 26" vs 29" bike test that we featured in issue #126.

This video might not make full sense unless you've read the article Steve Jones wrote in last months mag but, basically, Jones set out to test if 29"x140mm bikes are faster than 26"x160mm bikes on the harder side of UK trail riding terrain.

I nipped over to the Forest of Dean in the afternoon to grab a few words with Jones, Rob Cooksley and James Richards (the two test pilots), the video chat ends a bit suddenly but you should get the idea that the big wheeled bike is faster in certain trail centre situations against the clock, but maybe not as exciting to ride as a 26 incher.

Have a watch then tell us your thoughts in the comments below and let us know as well if you read the magazine article too.
