Have a look at www.tartybikes.co.uk, they have stems on there, you might be better with a longish 100-120mm stem with between 5 and 15 degrees rise, depending on your height obviously. Alternatively theres the F.S/wanted section on here but seeing as your a new member you'd have to get their msn/phone number and ask them really politely to sell one to you. Or you could look on ebay. Echos are good, as are onza stems, seen a couple of snapped viz ones and i've heard good things about the toxsin stems. choice is yours.
