Good start! The first thing I bought for my next build project was the Q/R skewers . . .

Don't get Cobalt wheels! Get some DT240s on Light Bicycle carbon rims or something, be far nicer.

Got a link and rough price?

Only have around £3,000 to play with...

The Rookie

Lurcher looks like a good basis, will watch this with interest!

£3000 - I wish!

Rims

Rear hub

Front hub

XD freehub body

Do you want me to build them for you as well!?

badly_dubbed

Feel free! Cos I can't!

Cheers dude!

Can't or haven't tried yet?

I thought the same, now rolling on own built wheels - worries the heck out of me mind, keep thinking one will taco due to my incompittance!

badly_dubbed

Haven't tried...did you follow a guide?

badly_dubbed

XTR 2x10 is also something im considering,

anyone got a good idea on what gearing to use?

40/28 or 42/30 or 44/30 crank

with

11/34 or 11/36 cassette

any thoughts?

njee20

Just get XX1, the range isn't that far removed from XTR double frankly! Significantly lighter too.

badly_dubbed

its the replacement cost thats swaying me....ill get a season out a cassette that costs £300!

njee20

Sum total of the transmission (ie rings/chain/cassette) is bloody close though, you save a bit on the cassette, but XTR rings are big money.

Change chains and you'll get a couple of years out of a cassette, and shop around and it's a good chunk less than £300. It also costs less in the first place - the chainset is about £200 cheaper!

But yes, I do agree.

quite fancy those built on some king hubs..!(Cheers Al @ wheelcraft for putting that idea in my head!) are they reliable for mtb...ive only ever used carbon rims on the road...whats this light-bicycle company like? dealt with them before?

interesting stuff!

Yep a mate bought the well known online guide for a build and lent it to me!

badly_dubbed

so heres the build list, minus wheels and bars (not decided on them yet any ideas? carbon/flat bar preffered) which ill order from light-bike and the Chris King ISO hubs from Al @ wheelcraft in campsie den who will be building them....hopfeully arrive midweek

edhornby

have you checked merlin and the german places for prices of the full groupsets, as opposed to individual bits?

gonna be a very nice build

njee20

Not nearly enough XX1.

Ditch the Crank Bros stuff - Ritchey WCS stem, you don't need a QR seatclamp on a race bike, just adds weight.

XTR race brakes over the Hopes for my money, particularly as there were some good deals once they announced the new version. Braided hoses add weight too - I'd not bother (unless that's the only choice?).

If you must go XTR get an 11-36 cassette, no point bothering with 10 speed otherwise. What you have there has a pretty similar range to XX1 while costing more and being significantly heavier.

Chris King hubs are heavy and need quite a bit of maintenance, for me they were a huge disappointment frankly, DT all the way. King headsets are awesome though.

Don't buy it all from CRC either, bet you can save a chunk looking elsewhere.

badly_dubbed

cheers, have looked around and have got a few items cheaper saved around £90 so far

thing is im a vain bast and stuffs gotta match....no reds/blues in the build lol gold/black/silver only...hence some of the items ordered...obviously they have to be decent too.

deffo sticking with xtr, again purely for damage cost...as this isnt a sole race only bike...itll be used frequently.

good point on the seat clamp...!

njee20

X01 coming in the next few months. You'll easily get a couple of years out of an XX1 cassette, it's only about £80 more than an XTR one, and it'll cost you more than that in initial outlay. Honestly think that's a badly thought out decision, particularly with those ratios as you have a near identical range.

My XX cassette lasted longer than XTR, being all steel the sprockets don't wear as much.

badly_dubbed

nothing solidly groupset wise paid for yet so time for thinking about it....i do appreciate the opinions, great stuff thanks

njee20

I just think that cost is the wrong motivator between those two. Having had XX, XTR 2x10 and now running XTR 1x10 on a race bike I'd definitely get xx1 next time!

Just noticed the price of that seat collar... WTF?! Almost as bad as the Tune one.

badly_dubbed

haha swapped out for a hope bolt on

njee20

Much more sensible!

The Rookie

Bar suggestion - Easton EC90

badly_dubbed

Was thinking about the Thomson carbon flat bar....

njee20

Mt Zoom, fantastic for nice light finishing kit.

badly_dubbed

cool ill take a look

has anyone direct experience with the carbon rims from Light-Bicycle?

njee20

I don't, but a couple of friends have them (one 650b and one 29er), and have no issues. I'd definitely get a pair.

badly_dubbed

just ordered a set, worth a shot...not going to expect Enve like quality...but you never know!

3K, 32h, Matte finish....also went for the wider profile just to be on the safer side.

still gonna go for the King ISO hubs i think though... (yea a bit heavier, i know lol)

rough cost of the wheelset will be £770, not including spokes and building...not too bad i dont think for carbon..?

njee20

Wasn't so much the weight of the Kings that annoyed me, it was the fact they were heavier whilst needing more adjustment and not rolling as well. Pretty though.

The rims come out of the same factory as Spesh/Roval rims, just a whole chunk cheaper!
