Depends how serious you want to take your racing. I raced one all last season but it's now been relegated to back-up race bike. No complaints, really, except:
1) the rear spacing was 135mm which meant 'pinching-up' a standard 120mm rear wheel, which made rear wheel puncture swaps a tad more tricky during a race;
2) semi-sloping geometry made it a little more difficult to shoulder (smaller front triangle);
3) there's too many 'extra bits' for it on to be a 'proper' CX racing bike (mudguard and rack eyelets, disk brake mounts, bottle bosses). Bottle cage bolts were removed from mine for races and holes taped over (bolt heads painful when shouldering);
4) the paint's made of cheese. Insulation tape will pull it off :O)
Apart from those niggles, they're truly excellent bikes. Obviously better suited as 'all-rounders' rather than thoroughbred race bikes.
