nick_the_wheelbuilder Posted August 19, 2023 Share Does anyone know what the lightest alloy 29er wheelset for mountain biking is? I'm busy with a very special wheelbuild (details once I have photos) and it's going to be very light for an alloy set. Carbon-light, in fact. Any info on any really light all-alloy MTB wheelsets (that don't cost more than a carbon set)? Spoiler alert: the set I'm building uses Stan's Crest Mk4 rims....

RobertWhitehead Posted August 19, 2023 Share American Classic is lighter than Stans . Me rida my bicycle and dasilvarsa 2 Link to comment Share on other sites More sharing options...
Me rida my bicycle Posted August 19, 2023 Share Yes the American classic race 29ers with light spokes where around 1300g built for/by a LBS owner years ago. I used to love AC wheels but they where soft so no low pressure, as with anything you can't have it all. Cappi and dasilvarsa 2 Link to comment Share on other sites More sharing options...
michaelbiker Posted August 19, 2023 Share Not sure if these are the lightest but they come in under 1400g https://bikeonline.it/en/ruote-29/1732-drc-3xl-wide-29er-carbon-ti-x-hub-mtb-sp-wheelset-from-1395g-2000000000000.html#/182-nipple_colour-black/192-number_of_spokes-28_ant_28_post/131-front_hub_standard-qr9_quick_release/133-rear_hub_standard-qr_135mm_quick_release/168-hub_colour-black/457-rear_wheel_dish-standard/562-spoke_type-alpina_blade_superlite/37-compatibility-shimano_sram_mtb_10_11s Link to comment Share on other sites More sharing options...

Prince Albert Cycles Posted August 19, 2023 Share In about 2013 I bought a set of Stan’s Race Gold for my Cannondale Flash carbon . They were just over 1300g and is still running albeit with a spoke and nipple rebuild and bearing replacement after 40,000 km. I weigh 80 kg.

nick_the_wheelbuilder Posted August 19, 2023 Share Oh, forgot to mention. Also BOOST. Link to comment Share on other sites More sharing options...

Not to come across like a box Nick but you mentioned that you're busy with a wheel build, therefore the BOOST part sits with the hubs and doesn't matter .

Well boost hubs are wider and theoretically heavier. In the past, stuff was often lighter. Narrower rims, QR hubs. So much focus is now on carbon parts, so it’s interesting to see what is possible with affordable alloy stuff.

nick_the_wheelbuilder Posted August 23, 2023 Share Ok, so admittedly this wheelset I've been working on may not be close to lightest alloy wheelset ever, but it came out nicely. Stan's Crest Mk4 rims laced to H-Works straightpull BOOST hubs with 54t star-ratchet freehub mechanism and xD driver. Pillar PSR Xtra1420 bladed spokes and black brass Sapim Securelock DSN nipples. 1470g before tape and valves. This wheelset is squarely in carbon territory, at about R10k less money. I'd love to know what you think! MajG, Prince Albert Cycles, Me rida my bicycle and 7 others 8 2 Link to comment Share on other sites More sharing options...
Hilton. Posted August 23, 2023 Share Very nice! How do you find the durability with the Crest Mk4's ? Rapunzel 1 Link to comment Share on other sites More sharing options...

Obviously they're not meant for big jumps and really heavy riders, but for average riders wanting a light wheelset for marathon-type riding and gravel, they're superb.

David Marshall Posted August 24, 2023 Share I once had a customer bring me parts to build the lightest alloy wheelset around. I can't for the life of me remember the rim brand but it was German and they had built very light 26" rims. Unfortunately they didn't transition to 29" well. It was the only time that I've had a wheel pretzel while building (at around 80 kgf). Needless to say they didn't last well. After that I threw out the workshop scale and all the aluminium nipples. Talking of light I see that Light Bicycle have built a carbon wheelset (road) at 718g. Disc and tubular. Rim is 180g Link to comment Share on other sites More sharing options...

If I turned the nipples more than half a turn each, it went all wonky. Took me about 4 hours to tension and true. There's light and then there's stupid. I'm convinced that once you go too light the wheels become so fragile that they're really impractical. Link to comment Share on other sites More sharing options...
