has anybody used one of these? thinking of getting one instead of using a BB mounted guide? looks really really small and neat, just wondered if/how it works when out and about?

Looks identical to this: http://superstar.tibolts.co.uk/product_info.php?cPath=56&products_id=495

Except it’s 10 quid more expensive than the SSC one.

I have one, fiddly to set up and could be better imo, but does the job. OK for the money and XC use.

was thinking of this or a e13 xcx – but have heard some people with the BB ones saying they can get knocked and work loose the BB Cups, which is a bit worrying if it de-threads your bb threads whilst its loosening?
