Your ideal bike is always going to be one you hand-picked every component yourself, and built. Two years ago, I started this sport and quickly got hooked. I rode a ton of bikes and realized my ideal, dream bike is NOT an LBS purchase already assembled.
I too, lusted after the SC Blur XC.....until I realized it was financially out of reach. So what did I do? I went with second best- a 2005 Cannondale F2000SL Optimo hardtail. I found out my Cannondale(after I built it) is way better than that Santa Cruz, after all. Not only does my Cdale weigh almost four pounds lighter- but it climbs like a rocket......compared to the SC Blur, and shreds singletrack much better than the Blur just because it feels like it weighs nothing.
Here are my build specs:
2005 Cannondale F2000SL Optimo HT
Suspension: Ultra Fatty DLR 80mm
Bars: Ritchey WCS Carbon flat 580mm
Wheelset: Mavic XC717 Disc/DT Swiss 240s
Shifters: SRAM X.0 twisters
Rear Derailleur: SRAM X.0 long cage
Crankset: Shimano XTR M960
Pedals: Crank Bros. Candy 4ti
Chain: Avid PC991 Hollowpin
Saddle: Specialized Phenom SL
Seatpost: Thomson Elite
Cassette: Shimano Dura Ace 11-25
Tires: Kenda Klimax Lite 345G
Basically, I built myself(w/ no prior experience) a 19-lb XC race bike, for under $1000. It took almost six months to do- but I was patient, and the results exceeded all my expectations. Thanks to eBay, Craigslist, the internet, and buying everything slightly used- I built my own dream bike......and did not know it, until I finally rode it. Do I still want that SC Blur now? Nope.....and what a relief, too.
Your ideal bike will alwyas be one only you can be proud of building. It will fit you like a glove, and just won't feel right to anyone else......but to you!!!!
