Hi guys

let me show you my racing weapon for next season. Its a 2012 rocky mountain vertex 990 RSL.

Here is the actual build list:

frame: rocky mountain vertex RSL 29er medium
fork: rockshox sid RL 29er 15mm maxle with remote lockout
seatpost: KCNC Ti pro lite 27.2x400mm
saddle: fizik antares kium
stem: KCNC sc wing 100mm
handle bar: MT ZOOM XL 740mm cut to 680mm
seatpost collar: KCNC
headset: cane creek with carbon spacers and Tune carbon top cap with black aluminium bolt
brakes: sram XO
rotors: avid HS1 160mm front and rear
shifters: sram XX grip shift 10 speed
front derailleur: sram XO
rear derailleur: sram XO
cassette: sram XO
chain: sram
crankset: sram quarq 39/26 rings
grips: ESI racer edge cut to 80mm
bottle cages: ebay carbon with blue alloy bolts
computer: garmin edge 500
wheels: dt swiss x1,5 straight pull hubs, 28 spokes
tires: maxxis Ikon 2.2 tubeless
pedals: egg beater 2

The stock bike weighted 9,95kg without pedals

here are a few changes I made with the weight savings or weight additions:

cockpit
stock raceface turbine 700mm flat bar to MT ZOOM 680mm flat bar: -83g
stock raceface turbine 90mm stem to KCNC sc wing 100mm stem: -26g
stock raceface next SL carbon seatpost to KCNC Ti pro lite: -61g
stock fizik tundra 2 saddle to fizik antares: -39g
stock sram XO trigger shifters to sram XX grip shifters (including cables): -38g
stock grips to ESI cut to 80mm: -70g

braking
removed front rotor adapter: -13g
180mm avid HS1 to 160mm avid HS1 rotor: -38g
shorter brake caliper bolts: -4g

Misc
stock cane creek top cap/bolt to Tune carbon top cap and black alloy bolt: -11g
stock seatpost collar to KCNC collar: -3g
stock alloy spacers to carbon spacers: -7g
removed plastic pie plate behind cassette: -23g
carbon cages: +50g

wheels
stock continental raceking racesport 2.2 to maxxis Ikon exc exo 2.2: +74g
removing tubes: -416g
adding valves: +13g
adding stans latex: +208g

Drivetrain
stock sram s2210 carbon crankset to sram quarq 39/26: +52g

total saving: 435g

actual weight: 9,515 kg

The wheels are very heavy at 1913g. A proper racing wheelset/tire/cassette/rotor will drop at least 500g if not more. I have some american classic hubs here waiting to be built on stans crest and dt revolution spokes, with continental raceking racesport tires, sram XX cassette and KCNC rotor with Ti bolts, should be light.

I could also cut the seatpost and save something like 25-35g.

hope you like it!






Nice details on the brakes


And on the rear derailleur


Also on the brake caliper


12mm rear axle


internal cable routing


the routing exits a removable port near the BB. The routing is easily done removing the port which leaves a big hole to exit cables


press fit BB


the sid RL fork


blue bolts, small, subtle details

Like the short HT to keep the front low and the sloping TT so the bar will not hit the TT. Vertex should only be made in Easton tubing though

Like it mate!

Nice build, you have an eye for the small details.. Further to that will you be rotating the brake banjos on the calipers to smooth the transition to the fork and the seat stay? The brake lines also seem quite long a free bit of weight savings..

Well done!

Keep an eye on the KCNC post. I broke the Ti bolts on my... and was never happy with it.

Very nice !!!

Lots of attention to details. Agree on the low front end. Makes it look "racy"...

Also, looks like you have an appropriate playground for MTBing behind in your backyard ...

if I rotate the bango, do I need to adjust anything or its a simple operation?

thanks guys, looking foward to ride the bike for the first time soon...!

hi,
can you tell me the real weight of the handlebar, before and after being cut?

thanks

Loosen the 8 mm banjo bolt about 1/4 turn, rotate it into place and then re-tighten the banjo bolt. No other steps are required, very easy to do..

Hi,

Nice build!

But how does it ride? Is it indeed very comfy?

Beste regards Rolfo

@prendrefeu

thanks!

@rolfo

first ride yesterday, a bit over 1 hour on the trails and 2 hours on dirt roads. It does keep its speed a lot better over small to medium roots. There is obviously more traction when climbing and cornering. Unfortunately, I couldnt push it at its best in the corners cause the trails were covered in wet maple leafs, very very slippery. On dirt roads, it keeps its speed better and rolls smoother. Very nice bike, I cant wait to push it hard in the trails and get a racing wheelset!

after a few rides I can add a few comments

the bike is harder to bunnyhop/wheelie VS my 26in
im not used yet to the slightly slower sterring, which makes me miss the good lines in faster technical sections
harder to pump
the rollover hability is neglectable over medium to big roots
a bit harder to accelerate (heavy wheels)

the bike rolls fast and really keeps its speed, especially on flat parts and descents
there is more traction on climbs and corners

Overall I love the bike and cant wait to really get used to it, the trails are still covered in wet leafs so its hard to really hammer it.

I highly recommend wider bars on 29ers which helps the steering. I personally ride a 760mm bar on my GT (I am 187cm) and ride the bike more over the front like how I ride/rode my DH bike.
