i'm planning to upgrade some of my parts on my current GT avalanche to do XC. this is the spec that it will be after upgrade.

Fork - 08 rockshox SID race (have not get)
stem - Truvativ XR oversized
handlebar - ABR oversized
seatpost - ABR
seatclamp - GT quick release
grip - GT
saddle - Velo Cr-Mo, 200gram
shifter - shimano deore rapidfire
derailleur - front shimano acera, rear shimano deore
cassette - shimano deore
chain - KMC z9000
crankset - truvativ isoflow
BB - truvativ powersline
pedal - VP197, 250gram
brakes - tektro aquila with avid 160mm front, tektro 160mm rear rotor and avid FR-5 brake lever
shifter cables - shimano XTR cable with jagwire housing
brake cable - shimano M system
wheelset (have not get) - mavic 717 rims, DT swiss competition spokes, 08 deore XT hub
tires - kenda kozmik lite II (have not get)
those which i did not state have not get, meats its on my bike already. feel free to comment on anything. building for XC. trying to make my bike as light as possibel. please comment if you think what is heavy. thanks. light isnt everything man. i would also train. looks ok, id get some good hyd. brakes if you plan on riding hard. It is a very strange mix. They call a spec like this a "Frankenbike" because it looks like things were replaced with whatever you had laying around.
You don't need the SID... get a Reba Air; kill the derailleurs and get either BOTH Deore or BOTH Deore LX. The Truvativ crank is iffy, get an FSA Gossamer Exo. The wheelset is WAY overkill compared to everything else except the fork- use Mavic 317 rims and Deore hubs. The pedals are cheap cheap cheap- it looks like you are going just for weight savings without thinking of bearing quality and service. |
