To win this lovely P30 chain device all you have to do is tell us exactly how many products you think are in the Dirt 100? Sounds like a trick question doesn't it? But maybe there are 100, maybe there are more, maybe there are less?

So excluding adverts how many are there?

An easy way to find out is buy the thing and count them.

Send your acurately counted predictions into Billy@dirtmountainbike.com, oh and in the event of a tie break also tell me why you deserve the prize.

There are actually a limited number of these available to buy from www.madison.co.uk. Click here RRP is £99.99 on all 3 fitments (BB, ISCG, ISCG-05) and the spare bashguard is £34.99.
