im 1,70m weighting 78kg, so for a cyclist, im a heavy guy. I ride mostly single tracks, love to jump, and my 1 year old cs-041 is flawless, I've actually ordered a new 15" cs-041 frame, because the 17" feel a bit big, with the seat being on the same height as the bars.

I've got zero issues on my 041. The frame doesnt rub my legs- maybe a question of bike fit.

How much does your wife heights? im 1,70m, and im running a M size frame, but sometimes it seems a bit too large.

seat post is Hylix from eBay around 50€, trimed to 300mm (120gr), seat clamp carbonice from r2 around 35€ (5gr.)

ill test the seat post tomorrow, let hope for the better, it flexes a lot though

updates:






Does anyone know where can i find a threaded rear mech hanger, that will fit this frame? Peter don't have any.

I've just bought a helix seat post to cut and fit to my 29er. The seller says it weights 152gr in 400mm length, but im planning cutting it to somewhere between 250-300mm. Since the isp weights around 30gr (kcnc parts) the post should be around 120gr, and im cutting maybe some 50gr of it out.

100gr seat post looks nice for 60€.

Im also thinking about hanging my 100mm stem for a same model 80mm, sometimes i feel a bit uncomfortable with my ridding position, a bit too stretched, which give me numb hand in long rides. Im only afraid of losing my very good climbing geometry (tested it last weekend on 20º+++ climbs offroad, and im very satisfied with it.

Since the bolts on the stem are steel, ill change it by some ti bolts (12gr savings). talking about ti, the crank brothers eggbeater ti spindles will also be ordered shortly, as they are starting to need some service.

Ive been looking for ashima rotors, and they are a bargain, but my ice tech are barely used. ill think about that for my next race.

the 8.5kg (2x10) bike is becoming a reality.

cheers guys!

From what I've been reading is that the 10sp derailleur will work with a 11sp shifter and cassette. The 40/42T cog is what the Shimano 10sp derailleur does not play well with. Shimano 10sp RD's do not like being adjusted for anything above the 36T it was designed for. There are workarounds like the OneUp RAD cage to get the 10sp RD to work with the 42T. With the added cost of the RAD cage...I think you're better off just getting the 11sp derailleur.

Be cautious with Ti pedal spindles. Most have weight limits. If you're above 86kg...keep that in mind.

thank you for your reply. For the time being, ill just use 2x10 until it worns out. Then ill change to 1x11. Regarding weight, im 75kg, no way i can make it to 86kg... and if i make it, i won't be capable of riding hard, as ill be fat.

my rear hub doesn't take sram cassettes.

In order to go 11sp, i need a shimano cassete, and a new rear mech, since the rear mech ratio isn't made for the 11p separation between cogs, and will misshift. this means a complete 11sp system. It was my fault, i went 2x10 because i feared the gear ratio was not wide enough for me, but it actually is, what leaves me with a very good, brand new, 2x10 system. is there any buyer? LOL

with the ti spindles, new ti axles, and ashima rotor, i can save around 200gr, taking it to 9kg, and with a 11sp i can save some extra 500gr. 8,5 is a world cup bike... even maintaining Ritchey wcs 120gr stem and a 170gr 710mm handlebar, and a reba... not going to mcfk, ultralite, and tune $tuff.

That's what I was talking about 

Hi mate, thank you for the reply, and the suggestions.

Presently im getting to know the bike better. It already suits me very well. Im happy with it. Anyway i would love to have it lighter. The fork option is something that im hopping to achieve at less cost, as i have a refund pending form CRC.com and i can still make good money on the reba sale.

Changing to 1x, has made most of my thought. Ive reached the conclusion that in order to use 1x, i need a wider transmission rate out back. This way im looking for feedback in 42 teeth cogs vs shimano xtr 11sp 9000. I don't want do walk instead of pedal on "wall"climbs,  and i don't want my top speed to be limited to 28/30 km/h. Therefore im thinking about it.

Ill check about the rotors and the skewers.

the bike now mounts a pair of schwalbe thunder burt 29x2.1, tl ready, 400gr each, making the final weight 9,2 kg. yet, a bit heavy for what i wanted.

im thinking about some way to shed some weight, im thinking about a new suspension fork sid xx sc (-100gr), Ti pedal spindles (-100gr) , changing to a 1x system (-500gr). But as it could be very expensive, it ll take its time.

By now im breaking some KOM and PRs.

at the end it ended with a shimano bb92.

unlike the fsa (spindle too short) the race face don't come with a bb.

the bike is finally assembled and tested. I really like the bike. every pedal stroke really propels the bike forward. very stiff pedal wise, but flexible enough to soften some rough terrain, as expected in a carbon frame. The build is around xt an xtr components, Next SL crankset 2x10, and a xtr rear train, cassete and rd.

the low on all this is the weight. I know im using my old tires, around 800gr each, but even with out this, the weight is pretty high, sitting around 10kg right now.

I was hopping to reach a 8kg bike build with 2x10 crankset (as i run some marathons, i need more than 1x11... at least till now).

Next week i should be changing to schwalbe thunder burt tires, tubeless mount.

I can see that in order to lower the weight ill have to spent some real serious money, in some periferics, and a 1x crankset.

im very happy with my saddle, was not cheap, but is though. Maybe a little too much. I weight 75kg, and it have never had a issue with it. You can search reviews on web.

my pics are huge, i have to upload it later
