TPE15: IRC Tire 27.5″ mountain bike treads weigh in, new tubeless cyclocross tire

IRC Serac CX Sand tubeless ready cyclocross tire

At Interbike last year, IRC added the Sera CX Mud for wetter conditions. Now, they’re completing the spread with the new Serac CX Sand, a file tread version for much, much drier conditions. It’s also suitable for grassy courses (that aren’t wet) and gravel sections. It’s sized at 700×32 and weighs in at a claimed 375g.

Also introduced at Interbike last year were the 27.5″ versions of their mountain bike tires, and now we’ve got weights and a few other new tires and goodies to show you…


Velocity USA Offers New High End Blunt SS Wheelset with Industry Nine Hubs



If you’ve decided you want to upgrade to some wider rims but aren’t looking for something of the carbon variety, Velocity USA has a new option worth checking out. Based on their latest mountain bike rim, the Blunt SS, Velocity is teaming up with another domestic manufacturer for a killer wheelset. Calling it their top shelf mountain bike build, the wheels use equally top shelf hubs in the Industry Nine Torch Series. Combined with DT Swiss Competition double butted spokes and alloy nipples, the wheels still build out to a respectable weight in spite of 32 spokes per wheel and the wide aluminum rims…

Brendan Fairclough Breaks it down on the Scott Sports Genius 700

What does a World Cup level downhiller grab when he goes out for a ride back home in Surrey? If we’re talking about Brendan Fairclough that would seem to be the Scott Genius 700. Contractual obligations aside, we’re also fans of the bike as it manages to blend a super pedal efficient ride with a bike that still wants to be rallied downhill. Of course, we only imagine we can ride the Genius like Fairclough, but it’s nice to dream right?


TPE15: American Classic gets fatter, wider and more tubeless for mountain, road

American Classic Sprint 350 wide road tubeless wheels

Whether it was rims or hubs, for road or mountain, American Classic’s offerings just keep getting wider and adding tubeless ready options, which should make just about everyone happy.

For the pavement, the Sprint 350 rims get a complete redesign to bring it up to modern standards. Inside width jumps from 16mm to 19mm (external is now 22mm), and it’s tubeless ready. The weight of the rim is spot on at 350g (claimed), and it’s built into a traditional road wheelset with 28/32 spokes (F/R) with double butted spokes and comes in at just 1,396g for the set. Retail is $899 USD. Their sponsored Pro Tour team, Bretagne, has been training on them and say they’re better than the race wheels they had last year.


TPE15: Kenda adds tubeless ready gravel, cyclocross & 27.5+ mountain bike tires, more!

kenda havok 27.5+ mountain bike tire

No tire collection would be complete these days without a mid-fat, plus-sized 3″ tire, and Kenda’s offering is the new Havok 27.5 x 3.0. It’s targeted to be around 900-950 grams and uses their DTC rubber compound that gets a softer rubber on the side knobs for better grip and former in the center for less rolling resistance. It’s tubeless ready, so stock up on sealant now.

OE tires will get a 30tpi at the beginning, aftermarket tires will have 60 and 120 tpi casing options. Might get a narrower 2.8-ish option if there’s demand, but will start with the 3.0.

For things that get lighter and narrower, keep reading…


TPE15: RST Teases inverted XC suspension fork, stealth dropper seatpost & more!

prototype RST inverted xc trail suspension fork

RST surprised us with a sneak peek at their prototype inverted suspension fork, which boasts a full magnesium one-piece upper. It’s aimed at the XC and trail crowd, but will get a 15×110 axle, the newer width being used for “boost” hubs. So it’ll likely work for the 27.5+ as well as 29er, though the latter is its primary target.

Internals are secret for now, but there’ll be measures to prevent the 32mm stanchions from turning independently. Expect a weight around 1,700g and travel options from 100mm to 140mm.

Head past the break for more details, pics and other new products…


RockShox Updates Sid, Reba, and Pike for Boost, Plus New Entry Level XC 30, Paragon Silver Trekking Forks

 MY15_RS_PIKE_RCT3_DP160_Front MY15_SID_RL_275_GLBLK_Front MY12_REBA_RL_2715_GLB_Front

With a new round of trade shows comes news of new products looking forward to 2016. For RockShox, the biggest news would have to be their new Boost technology which involves the widening of both the front and rear axles from 100 and 142 to 110 and 148mm. As previously discussed, the change allows engineers to add another level of stiffness for bigger wheels while simultaneously providing more clearance for tires and frame components. If you were concerned about the stiffness of 29″ wheels up until now, this could be your answer.

Released in conjunction with SRAM’s new Boost compatible ROAM 40 wheels, X0, and MTH 700 hubs, RockShox is starting into Boost compatible forks with three models for 2016. Starting in June of 2015, 29″ Boost compatible SID and Reba forks will be offered which will also fit 27.5×3.0″ tires. RockShox will follow up with a Pike 27.5 Boost and 29″/27.5+” Boost fork later in the Summer.

The forks will all have the wider axle spacing, but the engineers at RockShox have a little something extra up their sleeve for even more stiffness…


TPE15: Marzocchi Espresso Dropper Post drops in, plus new Enduro & XC Shocks, and more!

Marzocchi Espresso Dropper seatpost first look and tech details

Marzocchi’s new dropper post has been spotted on rare occasions over the past couple months, but now it’s springing forth with real details.

The EPD, or Espresso Push Dropper, will be available in standard and stealth versions, and in 31.6 and 30.9 diameters. Travel is 125mm at launch, and later this year they’ll have a 150mm version, too.

The name comes in part from their slick Espresso coating on the stanchion, which help it stay smooth through all manner of conditions. Inside the post there are three roller key guides to keep it sliding straight up and down and prevent rotation, which seemed to work pretty well…
