Beone cx build

[J00P]

Hello,
I have just ordered a 2011 BEONE CX raw frame (cantilever) and hope to build it up over the coming weeks.
The idea is to keep this a "budget build". I will initially build it up using ultegra 6700 and Aksium wheels parts that I took of my Caad10.
In the mean time, I will look for bargains on lighter parts. Preferably with campagnolo.

I would like your feedback on:
- canti brakes ( weight, price, braking power)
- clinchers: are carbon wheels & canti brakes a good idea for CX? or just some standard fulcrum or campagnolo? (weight, price)
- light weight tires, with not too much profile, I am not going for "deep mud" should also be fast on road.
- suitable head set for CX
- 10 sp vs 11 sp (centaur vs athena or 2nd hand SRAM red?)

Thanks for advice,

IF you want to use Campagnolo in CX it won't be budget . Not becasue of equipment price, but levers ( TBP : lever body ) replacement.

Campy levers body brake after EVERY SINGLE ONE fail… in case of Chorus/ Record you can replace body ( 3 weeks waiting time , 70€ ) , all powershift ( veloce, Centaur, Athena ) - set of levers . After season you will have campy cables for life ( they come with levers set )

It's just case of design- it simply must brake.

10 vs 11 spd : generally 10 is easier to maintain and setup. Work better in frozen / muddy environment - but difference is not so big to "suffer" with 10 spd drivetrain vs 11 . Or opposite.

Brakes : FME, I would make ranking this way :

1.TRP Revox
2. Campagnolo canti
3.Avid Shorty Ultimate
4. TRP Eurox

and there's no nr 5.

Shorty Ultimate position will raise ( 1 place ) after yoke change - for type which you can clamp straddle.

If you won't go to nasty mud, consider Mini-V ( TRP cx 8.4 sram/ campalevers or /9 Shimano levers) - better power, tiny bit worse modulation and clearance.

Wheels : best are with easy to change / mainatin bearings. Fulcrum R5CX are very fine. LG even better. It dpends on budget, but it has to be big if you want to use carbon rims in cx and canti… Braking is not even half good comparing to good alu rims.

Buy wheels which you can afford to crash / damage .

Tires : Challenge Open Tubular - 300TPI, glued thread , good lifespan. I use Grifo & Grifo XS. More than happy. 1 season zero flats, 2nd season series ( 3 in 1 day !!! ) after change for butyl tubes , after come back to latex : Zero flats again.

Relatively good and very cheap ( and very fast ) are Conti Cyclocross Speed - u can buy them cheap on fleabay, cause it comes as OEM in many bikes. AVOID at any price Cyclocross Race- horrible tire : flat after flat after flat…. never ending story, however I should say that extremely short lifespan is good in this case : you will get rid of them faster / 1000-1500km is absolute max expectable /

I would echo stormurs' suggestions on brakes. For racing, right behind choosing the right pressure in the right tires, my opinion is brakes come in third in importance, and it is a good feeling knowing you have ample power to stop and do so consistently. My suggestion is you look at TRP CX9's for your Shimano levers.

Have fun with your build.

It's hard to believe in 1140g cx frame in this size …(scale issue ?). If I'm wrong, it seems that any S-Works, Giant Advanced, BMC CX are extremely heavy frames in comparison

10spd Ultegra for CX is very OK ( but I'm not a "fan" of Shimano… ) , chosen brakes are very not OK .

Don't go "light" for seatpost. Trust me 3T Limited is to fragile f.e. for cross, this knowledge cost me 220€ If you want your bike rideable and reliable, 200g for seatpost is OK, consider your weight !

Crank : I like Rotors, reasonably light, 3D24 fits everything on the market ( Shimano standard ) so fully future-proof. Chainrings : Miche Super11 ( I know it's "campy" but fits perfectly for any 5 bolt 110bcd crank wo hidden bolt ) or Stronglight CT . Same for BB : Rotor is far more smoother and longlasting than Shimano.

If you want cheaper and still good : Shimano CX70 or Ultegra 6800 36-46 - both under 200€ . And you'll have "homogenic" drivetrain.

Next Q is Why Aksium ? It's not most reliable and CX resistant wheelset for given money… Fulcrum Racing 5 cx LG ( wide rim ) is far far better choice. Basically any Fulcrum is better choice than Aksium ( no, I don't work for Campagnolo, but I'm opened for proposition , and no, I don't have Mavic trauma either )


Brakes : if you're "recreational", and won't go into deep ( really deep ) mud/ snow , go TRP mini-v's ( CX 9.0 for Shimano levers )


Tires : 2 sets for beginning : Conti CX Speed ( file thread for hardpack )or better : Michelin Jet , and Michelin Mud2 for soft ground( both are 33mm instead of marked 30mm ) . Both are very "tubeless ready" , long lasting, or work very very fine with latex tubes ( challenge cross weight about 75g only ( road 55g, but it's risky for 33mm tire ) . If you will have 1 set of wheels , tubes then, no sealant- no point, to often changes.

F.e. MUD 2 tubeless on Hed C2 rim being 85kg I rode 1.3 front, 1.5 bar rear. VERY risky ( start burping a little on roots ) but on gravel/ flat courses very OK, ) 1.5 -1.8 worked perfectly regardless conditions.


If you don't have seatpost, stem & bar , I would go all Fizik - carbon(R3) seapost and alu stem-bar. very good value for the money. Take more drop handle bar to have better hand position for braking and steering on drops.

Thanks for the advice! Unfortunately the brakes are already on their way...
We'll see how they perform. As I m a beginner, and not doing any races, it might not be that critical
The aksium wheel set came form my caad10 and it is economical to recycle it, but those wide fulcrum rims sound very promissing!
A used sram force crankset is on thr way!

Been doing racing cross and do cx off road training during the winter for 20 odd years on Campagnolo levers (8,9,10 speed versions) and have never broken a lever..........ever!! Currently using 10spd veloce levers which have been on the bike since 2010.

[stormur]

You are extraordinary lucky.

It's not opinion case , it's just Campy levers design, to fragile for side impacts : any side impact cause brake lever rotation , slip off holding pin and lever body break( brake lever work as big side leverage ) : it's just by it's design. Happened to me on Centaur, Chorus and Record lever bodies… Even very light mount doesn't help : force to move lever on the bar is still higher than required to brake lever body … .

FIRST side impact and it's broken.

So, maybe you have it broken, and even don't know that … (?). Or you never have not fallen ( hard to believe either ).

Building is done for now; used mostly parts that I had laying around.
Not the best WW choice, since I took them off the CAAD in the lightening-process of that bike.
For now, it will do. New (or used) parts that had to be bought were selected on weight.

Should add up to 8.2 kg

I have regular compact chain-rings, the 50T should probably be replaced by 44T at some point.
In the future handlebar, wheels and shifters might be replaced by lighter parts if I run into these.

Time for an update; inspired by Kevosinns Addict thread I ve scraped the frame



I won about 20 g on the fork and 40 g on the frame.

Also components were changed;
Zonda wheels (1550 g)
Ritchey evolution SL handlebar (185 g)
Campagnolo chorus crank (650 g)
Campagnolo Chorus shifters (344 g)
Campagnolo Chorus RD (...)
I just got hold of a barely used Red cassette 11-30 (185 g) it should arrive next week.

The frame is only sprayed at the bracket en the saddle joint and I applied some aerospace protectant303.
