I'm currently evaluating a Genesis Altitude in 853 variety (20 & 30 are the same frame), did the Temple Newsan ride on it but it wasn't really varied enough to get a proper taste so will hopefully be out this weekend and over Easter to give it a good varied run , initial impressions are good and it was about £100 >£150 less than a cotic Soul frame (2nd hand!), I'm using all the bits off my M5 Stumpy so the running gear is like for like in effect apart from I've removed the spacer from the forks to take them up to 100mm (Altitude frame asks for 100 >120 afaiaw). It's not got the bling factor of the Cotic but it seems to do the job for a lot less buck (Bit like Skoda and Audi , you pay a lot more for the 4 circle badge!, I've had both so can give an opinion). So far for a £130 853 frame I'm happy , the next few weeks will tell. I'm mainly XC btw.
