Anyone had any experience with this wheelset in terms of stiffness and durability? It's only 1250g without skewers.

Unfortunately there wasn't much review on this wheelset except from bikeradar. Below is an extract:

"Looking like a great wheel for climbing or the northern Spring Classics, the Trimax Carbon TC24 has an ultralight 24mm deep tubular rim, which is 23mm wide and offers a great platform to make the most of the available grip. With PRA hubs and 20 front and 24 rear aero spokes, the TC24s tip the scales at 1,250g and the 3K carbon used means they're very strong. In use they instantly feel incredibly surefooted because of the wide rims, and the lack of mass makes for very lively, agile wheels that accelerate rapidly.

Still laterally stiff but offering more comfort than the deeper section rims, the TC24s are very versatile wheels that could also excel at cyclo-cross. They were so much fun that they brought out the hooligan in us, encouraging us to flick the bike left and right, surging, braking and trying to upset them. We couldn’t, but we enjoyed trying."

And the marketing on the PRA hubs

"The rear hub now boasts a wider stance following feedback from professional riders who asked for more lateral stiffness. By moving the non-driveside flange outwards by 10mm, wheel stiffness has been increased by up to 26 percent. A redesign of the hub internals has banished steel for a totally alloy freehub body, saving 20g and reducing inertia. Super-smooth running is taken care of by four easily replaceable sealed cartridge bearings in the rear hubs and two at the front, all mounted on 17mm diameter axles."

Pretty tempting to purchase to try it out since I have plenty of 20-30% hills to tackle in my neighbourhood.

Well bikeradar is a real reviewing authority
