I currently have a full suspension bike (Cannondale Jekyll 600), which I use for trail riding and local MTB races. I lock out the rear suspension 90% of the time, as it is unnecessary in most cases and saps power delivery to the rear wheel. It also weighs 30 lbs, which matters in races where there is a lot of climbing. I'm looking for a good quality, lightweight hardtail for under $1500 and would like some advice on brands and models. For example, I looked up the Trek 6700 Disc, which retails for $1370, but really don't know how it stacks up against other brands or models or if it represents a good value. I'd appreciate any advice on this matter. Thanks.
