Taipei Show: American Classic Mags Make a Comeback, Sneak Peek at new Carbon MTB Wheels

American Classis Mag road wheels, new carbon mtb wheels (5)

Don’t call it a comeback. Or do, either way, American Classic is bringing back their lightweight magnesium race wheels. Thanks to a few vendor changes, the new Mags are completely reworked except for the extrusions and will offer an impressively light race ready wheelset. The Mags will have the roadies excited, but the promise of new carbon mountain bike wheels should be good news to those who prefer to ride offroad as well.

Details after the break.


Taipei Cycle Show: KS Hints Towards The Future Of Electronic Dropper Posts

Taipei Cycle Show: KS Hints Towards The Future Of Electronic Dropper Posts

What’s better than a dropper post? A dropper post with no cables or wires. We’ve heard of wireless options in the works from Thomson and TranzX and now it looks like KS can be added to the mix, at least with a proof of concept. Hidden in plain sight in the KS booth next to the waterfall, there was a working prototype which basically was just to show the remote working the post. Apparently, modifying the LEV post to work with the system was fairly easy since the post is actuated through a valve in the oil circuit. By replacing the mechanical switch with a piezoelectric valve, the seatpost can be controlled electronically.


Spy Shot: New Limited Edition TLD Specialized Enduro 29er (UPDATED)

TLD Specialized Enduro 29erAn anonymous shop wrench at a Specialized Dealer just shot over this picture of a the yet to be released S-Works Carbon Enduro 29er. We don’t have any details yet, but official word from Specialized is that the frames are already sold out! That doesn’t surprise, we had the opportunity to sneak one of the big wheeled brutes out for a ride before the official launch last year and fell in love

UPDATED: Official pics after the break


Frostbike First Look: TRP’s New Spyke Mountain Dual Piston Mechanical Disc Brake

Frostbike First Look: TRP's New Spyke Mountain Mechanical Disc Brake

After TRP introduced their Spyre dual piston mechanical disc brake for road and cross bikes, an interesting thing happened – they started getting a lot of requests to make a mountain bike model. Even with a number of excellent hydraulic brakes on the market, apparently fatbike riders especially were looking for a mechanical brake that was better than the current options and not susceptible to cold like many hydraulic brakes can be. In spite of the bumpy roll out of the Spyre, the performance of the brake is impressive and now after the recall new models are shipping to satisfied consumers. Enter the new TRP Spyke, a mechanical dual piston mountain bike disc brake.  Currently still in the prototype phase, it shouldn’t be long before these hit the shelves.

Thanks to TRP we got our hands on a prototype set after the break!


Spy Shot! Prototype 2015 Campagnolo Super Record “Light” Groupset

2015 campagnolo super record light prototype crankset derailleurs and shifters group

Submitted by an anonymous tipster and spotted aboard an Ag2r team’s Focus Izalco Max, these presumably prototype Campagnolo Super Record “Light” cranks, derailleurs and shifters could represent the next generation of the Italian brand’s top level mechanical groupset.

Technically, the “light” part of the name is the unknown. CyclingTipsFacebook shows other photos of them dubbed SRL, which we interpret at Super Record Light. However, S.r.l. is also the Italian equivalent of LLC, hence the company’s Campagnolo S.r.l. business name. But we doubt that’s it.

Inspecting these and CT’s photos, the rear derailleur does look a bit leaner, but all appear with the usual phone-cam fuzz, so hard to tell. Graphics are different than current gen, using all-white for now…


Nicolai Releases First Ever Pinion Gearbox Fat Bike, Laughs at Snowmeggedon

2014 Nicolai Argon Fat Pinion gear box fat bike with belt drive

If there were a weak link in fat bikes, particularly when they’re hitting the snow, it would be all that exposed drivetrain. So Nicolai created a Gates Belt driven model with the Pinion internal gear box, keeping all the moving metal bits out of snow’s way.

It’s not the first time Nicolai has messed around with their fat bikes – they showed off a full suspension prototype last spring. This one’s actually hitting production soon, though, and is a modified version of their standard (also belt driven) single speed Argon Fat. Besides the gears, it also adds front suspension via a 120mm Carver Trans Fat fork.

The result is something that makes the rest of us here want to hop on a fat bike. Well, the video of this thing shredding the Harz Mountains is what makes us wanna get out there – but if you’ve gotta choose a bike…

Drop in for all the action…


Trek World Racing Testing Prototype 650b Sessions for Down Hill


It looks like the Instagram “leak” from Brook Macdonald last week was a bit of a precursor to the official press release today from Trek World Racing. Not that anyone was doubting the merit of the bright red 650b prototype, but now it is official – the team will be starting the season on 650b prototypes of the Team Issue Session 9.9. Trek mentions that the goal is not to replace 26″ wheels in the gravity category, but to investigate the benefits that 650b wheels may provide in a World Cup level setting. Trek’s MTB Product Manager John Riley had this to say,  “After all of the research we’ve invested in wheel size performance characteristics at Trek, we believe 26” wheels absolutely still have a place in the gravity category. We’re keen on understanding the possibilities of 650b as well, so we’re evaluating that option with some of the world’s best riders on Trek World Racing.” All of the 26″ Sessions will still be available in the coming year including the Race Shop Limited Session Park.


Spy Shot: Trek Session 650B Downhill bike


While Americans where attempting to sleep, Trek World Racing’s Brook Macdonald was getting ready to race the New Zealand National Championships. His secret weapon? A beautiful new paint job that partially masks the contours of his prototype 650b Trek Session.

It’s hard to tell was kind of special trickery the engineers at Trek have employed on this new bike, but the frame looks a little leaner than Ye ol’ Session, and the front triangle has a decidedly carbon look to it.

Big in BMX, Box Continues to Hone in on Mountain – Shifter, Derailleur Closer to Production


If you haven’t heard of Box by now, chances are you’re not into BMX racing. While the company has been working on some very intriguing mountain bike parts, like the shifters above and some hydraulic disc brakes that we saw at Interbike, Box has introduced a number of new parts for BMX race bikes that make up some of the stiffest and lightest bikes out of the gate. As the high-end arm of Promax, Toby Henderson (formerly of T.H.E.) took over the Promax brand about 3 years ago and with the help of senior designer/brand manager Michael Gamstetter, and Engineering product developer Colin Esquibel, new products have been designed in California and are being produced with all new tooling. After the early focus on BMX, Box is on a mission to enter the world of mountain biking with some refreshingly innovative components like the push-push shifter.
