from me :)

how many?

Only broken 1, but probably worth having a couple of spares. Where are you?

Hey guys I've used some spoke calculators and they're telling me that I meed.

36x291.6mm spokes.
18x292.4mm spokes.
18x291.1mm spokes.

So which spoke size should I purchase?

Sounds like you should be able to get away with 72x 292mm?

I'd certainly round down from 291.1 to 290, and 292.4 to 292.
I'm a bit unsure, but I'd probably round down from 291.6 to 290 as well.
Or, you could try to get 291 spokes? Most shops tend to just carry them in even numbers (290,292,294...), but odd numbers are manufactured.

Yeah that's what I assumed. Unless people think differently?
Thanks for your help!

Does anyone have any experience of the AL33 rims from AForce? I need a new set of wheels for my Enigma, as I ended up having to make an emergency new front wheel purchase halfway through Transalp. One more decent descent and the front rim was going to fall apart. After having had to chop a Dura Ace C35 to rescue the hub, I'm definitely not getting another factory wheelset, but I definitely do want aluminium braking surfaces. And the emergency purchase RS11 front wheel, while no doubt functional in its own way, is not staying on the bike.

I know the XR31t is the sensible choice, being cheaper and more aero at sensible yaw angles, but I keep on being tempted by the smoothly rounded curves of the AL33.

Flo30?

Got some already, natch. Too heavy for this bike. It's the one I keep in southern Switzerland, so it goes up and down a lot. I try not to be too much of a weight weenie, but 100g a rim is more than I can bear.

So hoping to hit the buy button on 650b wheel components for the Isen lol biek

Hope RS4 hubs (I have hope service tools and like their stuff and want shimano rotors)

Planning on using Schwalbe G One 40 mm tyres and possibly WTB resolute 42mm tyres.

Rim options narrowing down to probably one of these two (both can take up to 70psi)

hookless, tubeless, 320g 22mm internal width

or

hookless, tubeless, 370g, 24mm internal width

which rim, and what spokes should i go for? currently thinking sapim d-light spokes

The weight penalty between Zipp's hubs o' cheese and DA 9000 that you will leave to your children is exactly one gramme. How did that happen. From @noblewheels Instagram

The rear wheel I built with Dura Ace 7600 hub and Mavic A119 has snapped 2 spokes in as many weeks.

The bike is a brakeless fixie and sees some 'spirited' riding but the brakages haven't been during heavy riding, rather the first snapped when I was giving it a wee true, the 2nd, today, while just riding along. And it really was just riding along!

The spokes are from 'Spokesave' on ebay so probably aren't the best but I've used them before for quite a few wheels without any problems. I do notice the heads are sitting a bit funny though. Almost as if the bend is in the wrong place making too deep a shoulder? Both breakages have been at or around the bend/shoulder.

I'm thinking I just need to rebuild with some decent spokes and it should all be ok? If so, what's the forum recommendation on decent budget spokes and where can I get a wheel's worth at a time?

Cheers.

£6 shipping is bare jokes though.

£6 shipping is bare jokes

It's a realistic shipping and handling charge, everybody else is just rolling it, at least in part, into their general mark up.

I'd be £3.90 to send 40 spokes and a pack of chainring bolts 2nd class signed for. 1st class signed for would be £4.40.

£1.60 would buy a hell of a fancy Jiffy bag.

Also, I don't have an internet retail business and so do not benefit from any kind of bulk discounts on shipping, and I'll be surprised if I do actually have to sign for the parcel when it comes.

As much as I might moan though, I've ordered from them as their price on the spokes is more than good enough to make up for the shipping charges.

It buys 20 jiffy bags if you buy in bulk, but that doesn't help much unless you can find a picker/packer who will work for nothing, from a packing station you can occupy rent free.

Point taken.

In the absence of any responses about Al33 rims, I've ordered some. 16:8 triplet rear, 20 hole front. Thinking of using Tune Mag150 and Mig45 hubs for the full moneygun.gif approach. CX-Ray spokes with CX-Sprints on the rear DS.

CX-Sprints on the rear DS

Seems unnecessary with 16:8, CX-Rays work fine for most people on 32-spoke wheels.

Where did you get them from? Also do you know the ERD?

Probably is unnecessary. But it's only 16g extra weight, and I'm not that much of a weight weenie.

Bikehubstore.com, and I think the ERD is 564mm.
