Wheelbuilding / Wheel Building / Wheel build help

I have a front wheel with (I think, it's destickered now) one of these rims (Rigida Zac 2000 'Dsic',

Some sellers seem to suggest this is a disc only rim, others say it can be used with a rim brake.

The cross section doesn't look much different to (Rigida Zac 2000),

So, other than that the braking surface on my rim being painted and not machined, any reason why using a rim brake with it is going to send me to a fiery death?

I understand the finish will deteriorate as I brake on it. In the long run I'd like to change to a black rim with a machined silver braking surface (Mavic A119 or something) but it would maybe be handy if I could use it with a rim brake for the time being.

I’ve used the Mavic Xm319&119 (disc) rims with rim brakes and it was fine. I did it because the rim looked identical to the A series that has machined side walls. I think it’s the same rim, with and without a machined side, and either way, those zac rims are pretty overbuilt so there’s plenty of material.

I would reconsider if it was a lightweight rim like pacentis, but I would really not worry about using a rim brake on the zac rims.

I have been building a 32h wheel with 8 groups of 4 spokes.

The eBay guy that sold me the rims told me that you can build it as "normal" with all spokes the same length.

I calculated them to be 289mm. I had 288mm at home so build then like that

I found out that when laced 3x, the 2 spokes on the outside of the group of 4 need to be 4mm shorter and the 2 spokes on the inside of the group of 4 need to be 2mm shorter.

So instead of 289mm, it should be 285mm + 287mm.

I hope this comes handy for people trying to build those!

You can, as long as your hub drilling is clustered the same way as the rim drilling. With your uniformly drilled hubs, the spoke lengths are obviously going to vary.

Pondering a relatively cheap and light road disc set

Pacenti SL25 24H (£20 each at PX)
Bitex BX106F / BX106R (£121 for the set at Spa)
Sapim D-Light spokes (~80p a spoke)

Should be around 1500g

So £200 for the parts, then someone to build them. Skewers, rim tape etc...
So... £300?

Or is it not worth the faff, and should I just look at something like the Hunt 4 seasons for £300 which are ~90g heavier but seem pretty well thought of

I'm 72kg, would be using them as an all weather set and would have something more fancy/aero for anything race related

What I wanted to hear! Will be seeing if I have some canti posts I can braze onto the fork of my Day One and ditching the disc then. #discbrakesaredead

Sapim D-Light spokes (~80p a spoke)

Save >£20 by using ACI, only 40-50g extra. I wouldn't use weight weenie spokes for 24H disc wheels. Actually, I wouldn't use weight weenie spokes at all, but that argument is well rehearsed.

I didn't think D-Light were particularly weight weenie (in spite of the name). Have a set of 55mm light-bicycle / Shimano CX75 wheels built by ugosantalucia and when I started talking about light spokes I was talked down by ugo.
Then again, the CX75 were only available in 28H I think - so guess that's a difference?

Cheapest place for CX rays? After 44 295mm spokes if anyone has spares. Cheers

I have only seen 294mm or 296mm not 295mm

Try bike24, starbike or george hall cycles

edit: or r2-bike are often "cheap"

Yeah, og for it

Yeah, go for it!

There's a guy on ebay called Ryan who cuts spokes to length so you should be able to get 295mm.

I have some forks I removed from my rim brake day one if you want..

Thanks for the offer but brazing the posts on would be half the fun!

Sounds it, I'd probably take that option too!

Unsure if this is the best place to ask, but best way to post some wheels from UK to France?

No idea but got a double wheel box you can have.

the r460's were not fiddley I just had a couple of unround ones and warranting them would have cost me £8 per box to send to TF tuned so I went off them (i.e it would cost me money to get my money back). That's was their problem. If madison could do the warranty I would not be annoyed by it all. Also, the rims that were fine were still not that round. The ADHN in comparison was difficult to get straight and the last two were not round at all. The Ryde Edge R13 rim in comparison is round straight and tubeless compatible. Everything the ADHN failed to be so my suggestion is use that rim instead.

A rim that gives a problem that is not easily rectified for me is a problem.

I have just received the Halo White Line rims from TREDZ.

Pleasantly surprised with them, much better feel than Kilin ADHN - the finish is better and the quality feels higher.

ERD is supposed to be 607mm, which requires 293.8mm spokes when laced 3x to "modern classic" track hubs.

I had 290mm and 294mm spokes leftover so laced them quickly.
290mm are too short, 294mm are too long.

292mm is what is needed so will order from CycleBasket.

I will report when I true / tension them to say if they are actually better than Kinlin ADHN

I could trim these (294) down for you if you're in the Walthamstow E17 area tomorrow. Have spoke cutting and threading tool at Racer Rosa shop. 10p a spoke.

Thank you very much for your kind offer - unfortunately it is slightly too far out for me otherwise I would have come over.

Thinking of getting some Chinese deep carbon tubular rims to build up shortly for indoor track use only but not sure what width to choose.

Given that 19mm Pista Evos are no longer manufactured is it best to go for wider 25mm rims for wider 23mm Pista Speed tyres or are 23mm wide rims still the ones to go for with these tyres? Or should I get the 23mm rims and stock up on 19mm tubs?

At the risk of being shot down... Re-using spokes, ok in the right circumstances...? Maybe?

I’ve ‘discovered’ some Sapim Lasers on an old wheel that just happen to be the perfect length for a new build. Virtually zero rim wear fwiw. The new wheel would be the same cross pattern/spoke count and I can replicate the placement of spokes, albeit a few mm of flange/rim difference.

It will be a front track wheel, so no brake strain. But... doable or death?!
