EB14: Saris Powertap Adds Disc Hub, Plus New Complete Alloy Wheels and a Look at Past Prototypes (Updated)

Saris Powertap Disc brake power meter hubs

Last year, Wheelbuilder.com introduced a titanium XD Driver Body for the Powertap Mountain Bike hub, which was something they helped develop. The issue was decoupling the braking forces from the drive forces to get an accurate power reading and not mess up the strain gauges.

What’s new is that the G3-based disc brake Powertap hubs are now available in either 24 or 28 spoke drillings, down from the original 32-hole MTB versions. They recommend 24 count for road and cross, and 28 count for mountain bike builds.

UPDATED: More tech and weight info added for new disc brake hub below, plus specs for DT Swiss rim wheels.

The disc brake rotor is proprietary, necessary to mount a disc where their electronics typically sit. They say heat from the rotor won’t affect the power reading since the strain gauges are totally isolated from the outside hub shell. READ MORE ->

EB14: New Ritchey WCS Trail Wheels, 35mm Bar & Stem, Lightweight Carbon Road Components, Teasers & More!

2015-Ritchey-WCS-Trail-650B-mountain-bike-wheels

As usual, Ritchey’s tradeshow booth was littered with new products for both road and mountain bikes, along with a prototype part. Technically, it’s a teaser to a possible prototype, but we’ve put the pieces together and it’s looking good.

As for production parts, the new WCS Trail 650B mountain bike wheels bring their wider, tougher component line to the middle sized wheel market. The hubs are convertible between QR and thru axles front and rear -including 20mm for the front- and the freehub can be standard or XD Driver. Disc mounts are Centerlock, sitting on forged hubs rolling on oversized sealed bearings. Inside width is 25mm.

IB14: SportCrafters HardDrive Prototype Reinvents the Magnetic Trainer

Sport Crafters trainer magnetic non slip ste box training  (4)

Since the lowly mag trainer was first introduced, there hasn’t been a whole lot of new developments to the tech. SportCrafters’ prototype trainer is set to change that. While the SportCrafters proto isn’t the first to offer progressive resistance, it’s appears to be one of the first mag trainers to offer fluid like feel without the, uh, fluid. Not only is the resistance improved, but the way the resistance is applied to the rear wheel creates a system that is both easy on tires, and nearly impossible to get it to slip.

With the goal of making the trainer competitive with the top models on the market, SportCrafters is honing in on the new design with plans for production by 2015.

Details plus a video of it in action after the break…

IB14: Speedplay Goes Aero with Zero System, Syzr Nears Production, New Walkable Cleats and more!

IMG_3073.JPG

At this point many have been expecting the Speedplay Syzr mountain bike pedal to make it to production. The good news is that according to Speedplay it has.What is perhaps more interesting though is an impressive number of new designs for the road side including the Zero Aero System. Richard Bryne told us that the starting point for the aero project was being told that their standard Zero pedal system provided the same aero advantage as a deep dish front wheel. That was the point that Richard decided to pursue a full aero pedal system which gave birth to the Zero Aero System.

Designed specifically for TT and Triathlon applications, the new pedal design claims to be the most aerodynamic available.

Aero is great and all, but we think the new cleat is what most riders will be really excited about.

IB14: Felt Shows Concept Hunting Fat Bike & Beer Hauling e-Cargo Bike

felt outfitter fat bike for hunting

The Felt Outfitter has been a pet project of Jim Felt for about 5 years. He’s a fly fisher and bow hunter and he and his son always carry in all their gear for days in the woods at a time. They set up a base camp and hunt and fish from those remote wilderness locations. When Felt started making fat bikes and e-bikes, a lightbulb went off.

The Outfitter can haul a trailer with 60-100 pounds of gear (this one’s a modified BOB trailer made to fit a bigger wheel and work with fat bikes). They’re working on their own trailer, though, they’re just not ready to show it. Look for that sometime later next year.

In the meantime, check out the details below…

EB14: Centurion bringing Discs to German Speaking Cross and Road Bikes

Centurion_Crossdrive_carbon_disc-brake_cyclocross_bike_prototype_complete

Centurion apparently has strong cyclocross ties rooted in the racing career of its founder Wolfgang Renner, and their focus shows in the development of this carbon cross prototype which is expected to be available for cross season a year from now. They have a carry-over aluminum cross range available now, but our readers outside of the German-speaking markets of Centurion can still drool over this nice looking bike from what is a typically affordable company and a development partner with the much bigger Merida.

Read on for a bunch of detail images of the Crossdrive prototype, plus a nice line of disc road bikes that are available now…
