We often get asked tyre weights around the mid-weight tyres where people don’t want to be dragging round a Dual Ply Maxxis DH tyre (always over 1kg) and are looking for something quicker for all-day use but still able to handle some rocky stuff.*

*Disclaimer: These are some weights of tyres that we’ve got in stock today (5 December 07, updated 4 April 2008/ 6 September 2008) and should be used as a rough guide only as tyre weights will vary from batch to batch.

At last they’re here – the NoTubes Alpha 340, Stan’s first foray into the world of road tubeless rims. The high pressures used on the road makes special high strength carbon beads essential to keep the tyres on the rim, but since Hutchinson solved that problem a Stan’s NoTubes road rim has been inevitable.

Despite all the work that’s gone in to the road rims it’s cyclocross riders who’ve been pestering us the most about these rims. The ability to reliably run normal CX tyres tyres as tubeless is something of a holy grail for ‘crossers and that’s where our test set of Alpha road rims will be heading – offroad.

We’ve built some onto some American Classic 105 and 205 hubs with Aerolite spokes and I’ll be fitting them with some Maxxis Raze CX tyres to start with. Price of wheelsets comes in at £637.20 with the American Classic Micro 58 front hub, or £677.70 with the 105 front hubs as shown here.

The samples we’ve weighed come in at just 357g each on average (4 weighed, 352g to 366g). The braking surfaces are machined flat for consistent braking and they’re tubeless compatible by running two layers of Stan’s 21mm yellow tape round and fitting the dedicated Alpha valve stem.

Finally we’ve got round to weighing the Maxxis XC tyres.

Dual ply as the name suggests are super tough, if you’ve a problem with single ply then these are the tyres you need, but there’s a catch – they’re heavy and over 1kg a wheel to drag around needs some thought and ideally an uplift. See the post on mid-tyre weights if you’re looking to ride the ups as well as downs.

all tyre weights were correct at 24 April 2008 and may vary from batch to batch.

It may seem strange but there are a lot of people out there whose bike will not be complete without carbon fibre jockey wheels.

We have been sent these by a chap in Hong Kong (or somewhere around there), they are very light, have nice bearings and we just might order some in for the shop if they survive our rigorous testing process.
