It's a 559M, for more details see here:
www.thorncycles.co.uk/thornpdf/ThornEnduroBroLoRes.pdfThe spec is as follows:
Forks - Magura Laurin 100mm (but could be Vanilla RLC 100 if you prefer!)
Bars - Easton Monkey Lite XC
Stem/Seatpost - Thompson
Rims - Mavic 717
Front Hub - Hope
Brakes - Hope Mono Mini F+R 160mm, Front floating rotor
Chainset - Middleburn Uno
Saddle - Flite SLR
Tyres - Conti Gravity (but could be Vertical or Blue Groove/Nevegal if you prefer!)
The hub has had a recent oil change and only about 500 miles on the clock in total. I think that's about it. Oh, apart from reason for selling. I don't use it enough and it's a shame not to be used. I'm afraid that I seem to use the singlespeed more these days. Lots of detailed pictures available just drop me an email if you want more info at:
