Are you still riding your R460 rims with T11 hubs? How are they holding up?


I settled on Boyd Altamont, wider, deeper and refined U shape. Fantastic wheelset!

Because they're not "U" shaped.

Mpulsiv, sounds interesting. How many km have you done on them? And how is the braketrack? The rim is light, wide and deep, is there enough braketrack? Or does it quickly wear off.

There are 2 versions of Altamont. I found it easy to mount tires on. My 25mm Continental 4000S II measure 28mm.
Lites: 435 grams for 25mm deep http://www.boydcycling.com/2016-altamon ... ront-wheel
Regular: 485 grams for 30mm deep http://www.boydcycling.com/2016-altamon ... ront-wheel
I wanted something to perform on par with Flo 30 and didn't care about weight penalty. As a matter of fact I wanted a stiffer and stronger wheel and chose more spokes 24/28. Some say it's an overkill for 74kg rider and some will say that extra spokes is the ticket to stronger and stiffer wheel that will stay true.

I don't know how many km I have put on them so far in last 4 months but wheels ride like a dream! Brake track is silver and it's standard 10mm unlike Pacenti SL23, where you have to fiddle with 8mm brake track. Also, I'm a big fan of Kool Stop salmon brake pads, whether it's dry or wet.
I wish they would sells rims like Flo. I would love to build these for velodrome track.

Maybe it is only the disc version available as a rim only? E
g. http://www.prowheelbuilder.com/catalog/ ... ategory/2/

I haven't looked for rim-brake version, as I was intrigued to try these for my next disc wheelset.

I am using a set of Flo3 rims currently and have been pretty happy with them. Especially after switching to Schwalbe Pro One tires which are easier to mount than the Contis. I think around 14k miles on those wheels now. I am trying to wear out my Hope Pro 2 hubs so I an justify a new build and 11sp; it might be awhile still :-)

Anyone checked these out? They sound pretty good and are a available with a black ceramic brake track. Maybe more expensive than some of the alternatives tho.

+1 to avoiding Pacenti sl rims btw.
Gp4000s/corsas/Veloflex masters are all really difficult on mine. Schwalb pro one tubeless were impossible (even with 4hands!!) without using a big bulky tyre jack, and who wants to cart one of those around in their pocket. I don't use those wheels anymore because I just don't trust that I can fix a tyre problem on tye roadside....time for another rebuild perhaps ;)

mrfox: there's already 6 pages of discussion on these rims here with the designer participating.

The Boyd Altamont rims (disc version) are marketed in the UK by dcrwheels under their own name I think. I did consider these but in the end choose the Kinlin XR31 because I like asymmetric rims. A local bikeshop having them at an attractive price was a nice bonus.

I have a set of the Flo 30s. They have been a great training wheelset. I haven't noticed any particular difficulty mounting tires. They're reasonably fast wheels for an aluminum rim, crosswinds are utterly unnoticeable.

I'm building up a new set of training wheels and I picked the Hed Belgium Plus. I've received rims but not hubs yet, so I can't offer ride impressions. The rim itself seems nice. The central point of the profile is quite a bit sharper than the Flo 30, but the transition from brake track to the rest of the rim is smooth with no ridge.


When I look on fairwheelbikes at the handbuild aloy clinchers wheels I see that HED Belgium (Plus) and Easton R90 SL rims are used.

Given the reputation and knowledge of hubs, wheels and spokes of fairwheel bikes, I don't think you can go wrong with both of these rims.

Why exactly are you against Pacenti SL23s, but plugging a preliminary design by an unknown entity that has little chance of ever being a success?

Granted the SL23s have had issues, but for a bleeding-edge light design I think it is sorted out pretty well at the present time. I'm still loving my Gen 1s after ~10k miles. No cracks, no truing needed, no problems, and the tight tire mounting is a bonus IMO.

Any word on why Boyd went away from the ribbed sidewall design in the Altamont rim?

Look at the rim profile of HED Belgium Plus. Its "V" shape.

No one is saying on this thread that they aren't. The market is shifting and we are starting to see deeper than 25mm as well as refined rim shape (e.g., U profile). Why wouldn't we invest into 30mm deep wheels with refined rim shape?
