The stem on my 'crosser is too long and steep so I'll take a punt on here and see if anybody would be interested in a swap deal.
Mine is a black Thomson X2 in 110mm length and +/-17 deg. rise. It has an O/S clamp and is in as-new condition.
I'd like to swap it for a shorter X2, 90mm length in either +/-10 or 17 deg., I'm not so fussy on the rise.
If there are no takers for the swap deal then I'll buy the stem I need from ebay and put the current one up for sale.
I'll try to get pics up later, when I get home from work.
