  • Industry Nine wheels are back

    The light, bright, stiff wheels from North Carolina are due back BACK NOW! in stock at JRA soon after 2 or 3 years away (that's why all our photos show old rims), sometime in December we hope now. As before we're building on Stan's NoTubes rims, with others to order if the spoke lengths match up.

    The first thing to notice about Industry Nine wheelsets is the bright colours and anodised aluminium spokes but there's a lot more to them than that. 120 engagement points in the hubs, unbelievable stiffness from the thick (but light) spokes, interchangeability between all the usual axle types...

    The wheels come in a few formats; Mountain bike wheels come with XC or Enduro hub options (details below), and 3 different spoke thicknesses. They are available in 26", 650b and 29er sizes, and with Shimano/Sram 9/10 speed or Sram XD (for XX1 11-speed) freehubs. Front hubs to fit the Cannondale Lefty forks are also available. Then there's a singlespeed rear hub too...basically there's an I9 hub to fit virtually any bike. Expected prices for standard colours (red, black, silver) is around £780 per pair of wheels, custom colours are extra (probably £60 - £80 per pair).

    I had a pair (the orange ones in the photos below) and loved riding them. The stiffness of the aluminium spokes and the Stan's Flow rims was like no other wheels I've ridden. They are strong too; I never broke a spoke or had the wheel go out of true even after a load of races and the Megavalanche.

    Then there are the "classic" hubs; same internals as the wheelsets but with conventional flanges for normal J-bend steel spokes.

    Finally the road hubs, these weren't available back when we first built Industry Nine wheels so we're still working out the options, but the hubs look every bit as good as the MTB hubs and come in at just 86g front, 240g rear with a 39(!) tooth drive ring and 3 pawls for low drag - road hubs just don't need the fast take-up of the MTB hubs.

  • 650b wheels on... Cotic Rocket

    The Cotic Rocket tries 650b wheels - fails

    Cy brought his latest bike the Cotic Rocket round to try with some 650b wheels, we really wanted it to work and at first it looked like there would be loads of clearance, but unfortunately the tyre bottoms out on the seat tube before full travel is reached so don't try this at home.

  • 650b wheels on... Intense Slopestyle

    We had to build up a pair of 650b wheels to try out but what to put them on... first up Jons Intense Slopestyle. The wheels do go round but as you can see from the photos only just.

  • 1st look as Singletrack try 650b wheelset

    "These wheels came from Just Riding Along, big fans of 650b, tubeless and anything slightly quirky!" say Singletrack World in their fresh good Friday page.

    wheelset here > DT Swiss 350 hubs laced to Pacenti TL-28 650b rims - £4

  • Prototype: Pacenti Mega-moto 650b


    Further proof that 650b is here to stay, Pacenti are working on an enormous DH dual ply 2.4" tyre. The one we have is a prototype, we are told the finished product will have more knobbles to improve the handling.

    What we know from the sample is that the tyre has an extremely rounded profile, much more so than most other tyres, for a smooth transition to the side knobbles. It will likely come in a lighter (well, 970g) kevlar single ply and the dual ply version shown here which weighs in at a fairly standard (for such a big brute) 1350g. The dual ply will be made in a tacky rubber compound.

  • bicycle wheel size comparison


    Curious to see how the 3 wheels sizes, 26", 650b and 29er/700c measured up against each other in real life with and without tyres so we got the tape measure out and wrote down some numbers.

  • Pacenti DL31 rim - and the elusive DT Swiss 240 Lefty hub

    A couple of long-awaited treats turned up just in time for Bespoked, the UK handmade bicycle show in Bristol last weekend (23rd-25th March 2012).

    We've been very impressed with Kirk Pacenti's TL28 rims so have been wanting to get our hands on the next rim from his lineup, the DL31. Weighing in at just over 500g for a 650b model (I think it was 505g but forgot to write it down and now we've built it up), it's got the same tubeless profile as its lightweight little brother and is impressively wide at 31mm. It's aimed at the hard-to-define AM - Enduro - light DH category and while I'm trying to avoid the comparison, it's probably a eyeletted, wider alternative to Stan's ZTR Flow.

    Just to make a really special wheel we laced the DL31 up to a DT Swiss 240 Lefty hub which we've been waiting months for. The hub is made to the usual DT Swiss standards, weighing in about 15g lighter than the standard Cannondale Lefty Si when you include the custom aluminium Lefty bolt. At £150 it's 4 times the price of the Cannondale hub but the bearings should be better and it will match up if you want a 240s on the rear.

  • Pacenti TL28 rims - first look

    We're pleased to announce that Just Riding Along have been chosen to import the new Pacenti tubeless-ready rims into the UK.

    First

     


    Kirk Pacenti is best known for pushing the 650b wheel size standard, and supplying frame builders with parts though his bikelugs.com business. However he's long had a desire to produce mountain bike rims to fill certain gaps in the market, the first was a collaboration with Velocity (the P35, which we featured in this article) but now he is developing his own range beginning with the TL28.

    The rim has an appealing combination of weight, width and strength and is fully eyeletted. At 28mm width (23mm internal), and just 360g (26"), 409g (650b) and 438g (29er), there is nothing else quite like it currently on the market which is why we were so keen to bring them in. It helps that it's designed to be tubeless compatible in the usual tape/valve way and the profiles we've seen look to be just the right shape for good tubeless performance.

    We are expecting  advance samples of the 26" and 29er rims in the next week. Production samples are expected in the UK around the end of November / beginning of December by which time we should have had a chance to give the samples a good testing in the Sheffield rocks and grime. The rims are aimed at normal trail riders, not big-air merchants; by his own admission Kirk is a wheels-on-the-ground kind of man. We, on the other hand, like to indulge ourselves occasionally with some inappropriate riding so we'll be sure to give the rims a good workout.

    Update: Prices now available. The rims will retail for £78.50 each, and are available to pre-order in the shop >
