hi there mate, well i bought it myself about 5 years ago on ebay and i've never suspected that it wasn't and never had any reason to question the actual make of the bike, its been a pretty awesome bike for me. The man i bought it from showed me receipts of all the work he had done to it which typically i cant find now, they showed all the custom work the shop did for him (upgraded wheels, suspension etc) and they checked out. Thanks for your concern, but i've taken it to a couple of different bike shops since i've owned it and nothing has ever been doubted, in fact it has been quite admired. The last thing i want to do is con anyone but i bought it fairly from ebay under that description so i think im within my rights to sell it the same way. Again thanks for your concern, cheers.
what a noob... I asked him what model and year it is.
