Probably against my better judgement but I'm thinking of selling my 2010 Nicolai Helius CC as I pretty much exclusively ride my hardtail these days.
It's a size large and is fitted with a 200x57 RP23 giving adjustable rear travel between 100mm and 137mm or thereabouts. Nicolai frames have a 5 year transferrable warranty so this is still valid for another 18 months. It's on the small side for a large and I'd say it would be suitable for riders from 5'9" - 6'1" (I'm 6'1" and have always felt I'm at the upper limit of the range). Its in great nick with just a some cable rub to the underside of the top tube.
I'm looking for offers around £550 for the frame, £700 with the Acros deep set headset and Fox Floats shown in the pic but I am prepared to listen to reasonable offers. I've not stripped the bike as yet but will try to get more pics in the next day or so if I get any interest.
