Classic looking 24h rims

asprilla

Can anyone recommend some classic looking 24h rims?

I was hoping to use TB14s but they only go down to 28, as to Ambrioso Excellight SSCs. 23mm wide would be a bonus.

Unfortunately, if you try googling classic rims you just get loads of pages about American Classics.

That's because a box type rim at 24 holes won't be particularly stiff... low spoke count and V shaped rims came together

Looks like its Velocity A23s then....

Unless anyone has any other ideas? Not the Archetypes, I've got enough pairs of them.

DT Swiss RR440 is you can get them. I keep on reminding Madison they exist and that they would sell if only they would import them.

I suspect they are not very good... I don't like single eyelets rims, you either have a strong V or you have double eyelets, single ones crack far too easily... I had a DT 415 (at the time called RR 1.1) that cracked as soon as I rebuilt it at 120 KgF... that's not exactly high tension... it's just right to avoid the NDS being floppy... every single DS eyelet developed a tiny crack... never ever used them again.

Also, box rims at low spoke counts are inherently bound to be disappointing... can be used for a front wheel, end of...

For reference these are to go on some 80s 7 speed C Record hubs I've got hold of;



They are 28/24 (would prefer 36/36 but it is what it is). So I'm looking for something in keeping with the look / era.

Absolutely beautiful... my advice is to grab (if possible) the last Velocity Aerohead rims... phone Brick Lane Bikes and ask them if they still have any (you might get a deal on them too). These are mini V, same shape as the A 23 but narrower, light at 410 grams yet at 28 will build stiff enough for a rear. They do look quite classic in my view.
Box type rims like Open PRO etc don't look particularly in keep with the era, as believe it or not they are quite modern

Done. Thank you.

Do they have them?

asprilla

According to the website, yes.

Fingers crossed then...
They are really nice rims... I have only built three sets of those before they disappeared and the Archetype wiped away any other rim

Just had a text to confirm delivery of my order for tomorrow.

They appear to have almost the full range in stock.

That clashes with the conversation I had last year... when they told me the rim was due to be decommissioned... suppose it's good news, it is a good rim, the only good clincher at that weight in my view

I built a pair of wheels using some 24h Aeroheads with bladed spokes and some AC classic hubs a few years ago - boy did they fly, about as fast as you'd get with some shallow rims and they made Ksyrium SSCs feel like air brakes. Rims were quite soft though, so build quality is critical.

Ugo, I use DT Swiss RR415 (front and rear) but I respect the tension limit of 1100N, they have been fine for me (I have put serval thousand of miles on my set) and I use them alot i builds and have not had any issues and I won't as I repect the weight limit and tension limits of the rim. If I use them on rear the rider should be no more than 80kg and if used on the front ( with the rear being a RR465) I have riders up 93kg are fine. This particlar rider does alot miles so if issues where going to happen they would have happened by now. 1200N is way too much for the RR415 it says so on the sticker on the rim which says max tension 1100N!

The aerohead the last time I talked to Big Mama distribtion was still in production then not then back in so Velovity has not decided to drop it yet but they have not decided to keep it either. I hope the keep making it but it is not a rim I have used yet. However the DT Swiss RR415 is better made rim than any velocity I have used or seen the evenness of the tension you get in build is only matched by the Archetype, a good thing as NDS spoke tension is so low with this rim you cannot afford variation.

Note to self build my self a set of aerohead wheels in purple before it too late.

Open PRO says 900 N, yet it can be built at 1200 and last for many thousand miles.... if a rim has a maximum declared tension of 1100 N and it can't be built at 1200, then it is a censored rim, I am afraid... you need to have a fair bit of tolerance, also because calibrations are what they are.
A rim in that price range should be built properly and have double eyelets... single eyelets are a cheap solution to cut a few grams... they can be found in many bottom end rims.

cycleclinic

Well we will have to disagree on that, If used properly the rim is fine. As I say I have not had a failure with one yet and I have used dozens. The whole point of the RR415 is to save grams. If you want double euleyts there is the RR465. There are many rims without eyelets too.

I am sure ugo you can ensure your spoke tensions are even and pegged to 1100N. If you can give the RR415 another go, it is a reliable tough rim. I have put thousand of miles on mine without incident.

All the problems with this rim I am sure are due to spoke tension beyond what it can take and being used for riders that are too heavy for it. If you prefer using other rims then fine but don't call it censored because you built the wheel with spokes tension it was never designed for. Chalk that one up to experinence.

Yes some rims like the Mavic OP you can exceed the recomended spoke tensions on. The RR415 is not one of those rims. There are others as well and you ust have to be sure about the best place to use them.

Which is what I call a censored rim... if a rim cannot tolerate a 10% excess tension over the recommended one, in my books it is a censored rim. Your/my tension meters rely on a spring... it is not exactly the latest technology in terms of accuracy and 10% is well within the margin of error of a freshly calibrated one... imagine one that has been used for 5 years...

Let's agree to disagree, there is nothing wrong in that... and I don't expect to be right... I just have my ideas
