my trek superfly, its pretty stock as i've only had it a few months. i've added tioga carbo bar ends as i'm old skool rider and can't get on wit riser bars. have also fitted hope anodised red jockey wheels not for performance but purely for looks! was a little tentitive about buying a 29er but got this for bargain price and to be honest really glad i got it cause its awesome and i love it....... ;-)
