Looks like I'm off to a good start... on a bike that I'm don't really have spousal approval on for another 2 years
* WTB Laserdisc Lite hubs. WTB site has them for US$275 R, US$180 F. Velogear.com.au currently has them for A$99 /set. Would be rude not to, I figured. 32 hole... I like lots of spokes, so that's fine by me. Means I can use a lighter rim.
* Velocity Aerohead OC. Velocity store has them for US$72.99 each. Upfront Cycles (just out of Adelaide) has 32h purple ones for A$22.95 each if you buy 4. I really like purple, and I'm sure I'll find a use for the other two . Assym rims on disc hubs is a fundamentally good idea... and allows me to use equal length spokes both sides, front and rear! Which brings me to...
* DT Comp spokes. Two sets at A$23 /36 from c r c. Apparently that's 17% less than RRP, but it's certainly cheaper than the A$1.50/spoke my LBS used to charge for Comps. Did I mention that I can use 32 equal length spokes on each wheel? Couple of spares... shouldn't need them if I build properly, but whatever.
And that, boys and girls, is a couple of hours wheelbuild time short of a disturbingly light, rather blingy, ridiculously cheap wheelset for this disc brake road bike that I shouldn't be building until my next significant birthday in 2015.
Rear hub: 265g
Front hub: 155g
Rims: 418g each
Spokes: ~200g /wheel
Nipples: ~65g total
----------------------
TOTAL: 1721g... which is pretty reasonable for a 700c disc wheelset that cost $200
Oops again

I have 8000kms on my CX4 with the novatecs and haven't touched them. That includes a fair bit of wet riding too and some mud.JBark wrote:I see the Novatec disc hubs mentioned a few times in the thread, thought I'd give my impression after commuting on them (D812) with my Merida CX4 for the the past 5 months/4000km.
1) They seem to spin incredibly well. Yeah, totally subjective, but spin the wheels with the bike upside down and they go for ages and ages.
2) The freehub is completely knackered after the winter rains here in Perth. Not exactly what I was expecting with a CX bike, and quite disappointed. Been getting quite a bit of slipping for the past week or so, took it apart this weekend and the pawls and the spots they sit in are completely corroded. Bit better after cleaning, but still not perfect.
Not even sure I'm going to bother getting it replaced under warranty, if it's just going to fail that fast again. Even the 10 year old Alivio hub in my MTB handled last year's rain without a complaint. I'll probably just use a buffing wheel on my dremel to remove/smooth out the corrosion, clean it up spotless, and run it until it fails. Then replace it with a Shimano XT hub later on, or something that can actually handle some rain. Just looked up those Bitex hubs, seems like people are quite happy with them, and the prices look to be very good.

do you really need a higher spoke count than the como - I'm really hard on my bike/wheels and don't struggle with the spoke count (remembering heavy spokes/hub/rim on the como)Mulger bill wrote:YES PLEASE!!!jasonc wrote:we just need pro-lite to do a 700c disc wheelset

Great wheels but I wouldn't commute on them, not the way I jump gutters.

My wheel build will be 32 holes front and rear. No point in worrying about spoke count when looking for strength.
As an aside, I made a start on bolting bits together today. If anybody is interested, check out my build blog, link in my sig, for more.

I would suggest that the minimum spokes for road disc wheels would be 28H front and rear, with a "strong" wheelset being 32H.

Hey James, checked the blog and its looking impressive. Jealous that you get to start to build and I'm going to have to wait until I can secretly purchase required componentsJustJames wrote:I'm going to (having a go at) building my own wheels, as a way of combining Campagnolo with discs.

You went with a Veloce group set, 2 questions, why veloce? And was it cheaper to buy as a set and sell the brakes or could you have bought individual bits as cheap?
I'm struggling with that part only because if I buy an Athena group set I would have to flog the brakes (for avid road bb7s) and the brifters (for chorus ultra shift)

As this thread - which you started - led to my going down this route in the first place, you really do only have yourself to blame...so suck up that jealousy.
Why Veloce? Well, it had to be Campagnolo, and I'm trying to manage costs where I can. I looked at Centaur Red, for the black-and-red- bling but came back to Veloce, and got most of the bling courtesy of red chainring bolts from Cell.
Pricing the gruppo components is a minefield. Ribble had/have/may once again have good deals on groupsets where you pick the bits that you want, but when I wanted to buy, the groupset builder wasn't working. The cost saving by buying the full gruppo and selling the brakes wasn't huge but it was simple...and I'm a big believer in keeping life simple.
I'm hemming and hawing between BB7's and Bengal brakes from Pro-Lite. I know Deon from Pro-Lite is a regular on here, and seems to be a dependable guy, and it seems that the Bengals may be better than the BB7's, but the BB7's are the known option. Bengals may well win out with me as they may be less expensive, slightly, and may be available in black. I need to check whether I can run 140mm rear brake with the Bengals, as they are supplied with a 160mm rotor.
(Just checked c r c...and they are out of stock, but show BB7's at around $19...less than half the price of BB5's I guess it's easy to list a cheap price when you have no stock to sell!
Oh, and abandon your plan of buying bike bits in secret. Sooner or later you will want to wheel out n+1...and then you will be BUSTED!
If it's any consolation, I've been enjoying this process so much, I'm already pondering n+2, which may well turn out to be a single speed hard tail 69er.

I know I'll eventually have to wheel it out, but ATM I'm purchasing with my "own" money and Xmas is coming... Current build is running at $2,182, but unlike you I'm trying to defy the rules and make this the last N!
Currently the things I am still tossing up is if its worth going to Chorus Ultratorque cranks instead of power torque Athena (long term worth it), if I can justify a $250 3t team handlebar to match the red/black colour scheme (vs the white/black team version) and finally if I should go speedplay instead of m520 SPDs (probably not).

My build will prolly come in at around 2/3 of your total. And while I could have bought a Merida CX4 for that sort of money, this has been a much more interesting way of doing it, and a way of spreading the financial hurt a little.
I'd like to have the bike completed in time for the Sydney Spring Cycle, but I'm not sure whether I will make that, because I still need to get my rims (later this week I hope), measure up, order spokes (which I would get around mid Oct) and then build up wheels once the spokes arrive.
Roger Musson is very clear that I shouldn't be trusting manufacturer's measurements of ERD, so if anybody has a measured ERD for DT Swiss R520 rims, I'd be interested to hear from you!
Edited to Add: Red and black bars...no question about it.

I built my DT Swiss RR585s using the ERD from the DT Swiss website, and it worked out fine.

I tend to buy the whole box if I need new rotors or pads as it works out pretty cheap and you then have spare parts on hand
If you are mainly on roading, go the bb7 road( silver) and not the black ( mtn). You can also open up the road wide enough when you are on dirt to avoid dust/ gravel rub but the black/ mtn open even wider so these really suit if it is muddy

I would prefer the darker calipers for reasons of aesthetics. If I understand you correctly, there is no reason why I shouldn't use the MTB versions on a CX build - is that correct?

You'll find the MTB BB7's are compatible with V brake levers and the road ones are compatable with road levers, swapping them around will see poor brake performance ensue.JustJames wrote:@baabaa

I run mtn on the drop bar ss 29er and road on the cx with the same levers (Cane Creek SCR-5). Find no difference in the amount of pull, feel or the performance. Also worth noting the mtn do not come with inline adjusters in the box as they are built for flat bar levers with barrel adjusters. You really do need in line adjusters and worth getting some good ones like…

These seem to last longer than the avid in the box numbers.
I see you have gone down the on one planet x way. Nice bikes (I have a ss canti brake pomp I need to use more),any chance you can run full housing for the rear? For me this makes for a better overall smoother and easy care set up.

Ah, I see the ETA of the impossibly cheap BB7 road calipers has been pushed back to November 11.barefoot wrote:No stock.rjk wrote:might be a mistake on the c r c site but $26.67 ea for front and rear, grab them
http://www.this link is broken/Mode ... elID=87369
Or I would have grabbed them a few days ago
We'll see what happens to the price of that line when stock (supposedly) arrives on October 3.
But now they're down to A$18.66 each.
If we wait long enough, they'll be almost free... and out of stock until next week

One question I do have is have you actually tried V brake levers with the MTB BB7's, you would then find the braking superior. I've found the type of setup you use to have spongy brakes when tried with V-brakes, they do work but are spongy compared to the correct lever, haven't tried it with the discs though.baabaa wrote:Yes, you could go the mtn if you really must have the black.
