Thanks for all the replies its very helpful to me because ive been out of it for too long. As for which bike to get im still undecided i really like the look of the gu but i dont know how it will feel with such a high bb if anyone has ridden one or can tell me why its so high (advantages disadvantages) it would be greatly appreciated. Also im pretty tall (6foot1) so i was wondering if ill look stupid on a bike with such a high bb. Another thing i wanted to ask is can anyone recomend any parts on both bikes which could do with upgrading i.e. freewheel because i had a very nasty habit of chewing them to bits on the koxx untill i got a profile rear hub which i never had a problem with. Ill be getting either one from tartybikes if you want to have a look at the specs to help. Thanks again for the replies and just out of intrest i sold the koxx on ebay a while ago and was wondering if anyone on here may have bought it it was a koxx marc cassio sprayed matt black converted to single speed with a black profile rear hub matt black koxx forks gold try-all bars gold front wheel and very well used LOL. Im not bothered about seeing it again or anything i just wanted to know if it is still going. vinny.
