Updated Shimano Acera Gets a Healthy Dose of Trickle Down Tech


Shimano just introduced a new reworked update to their budget Acera mountain bike groupset, which will now also be offered in a separate trekking-specific variant as it’s become quite a popular spec in that segment. Shifting stays with 9 speeds like the previous Alivio/Acera generations, but gets updated to a new Mega 9 Lite that sees some optimization. The big difference is of course the upgrade to a Shadow rear derailleur for the lower profile, which was developed with more aggressive riding in mind. The front derailleur cage also gets reshaped for better shifting and gets a slightly more compact clamp and link layout that could shed a tiny bit of weight, all while improving tire clearance.

If America ever decided to redesign their flag, I’d immediately nominate Troy Lee to draw the stripes.

You may then ride it anywhere and not have to return it to the spot where you originally got it. Visit the Spokefly site for details and how you can make money by putting one of your bikes into service.

  • We want to send our get well wishes to Debra Banks of Rivet Cycle Works. Several weeks ago Debra was out on a road ride with friends when she and some of the other riders were struck by a drunk driver. Unfortunately Debra suffered a severely busted ankle requiring 7 hours of surgery. She’ll be off the bike for a while and also won’t be able to make it to NAHBS as she cannot put weight on that ankle. Get well Debra, and we hope you’re back on the saddle real soon.

Giant DH Bikes Get Advanced with the new Carbon Fiber Glory 27.5

Glory Advanced _1

One look at the times from a World Cup should be all you need to know that DH races are won and lost by seconds – sometimes even less. As downhill bikes have evolved, the recent trends include the move to 27.5″ wheels and carbon fiber frames. Both technologies are an effort to squeeze every bit of performance out of the machine for an all out, mash on the pedals run to the bottom. Developed with Colombian DH phenom Marcelo Guttierez, Giant introduced 27.5″ wheels to the Glory line with the ALUXX SL frame last year. A continuation of that quest for speed, the new Advanced 27.5 Glory builds on the proven race pedigree of the aluminum model, but sheds a bit of weight in the process.

Calling it the lightest DH frame Giant has ever produced (as it should be), the Glory Advanced is poised for the podium…


Shredits: Farewell to the Post Office Jumps, SF Composite High School MTB, and an Inspiring Trials Clip

If you didn’t already know, the Post Office jumps are no more. The iconic dirt jumps located in Aptos, California have been featured in countless video parts and played host to sessions of the biggest names in freeride. Under constant threat of being torn down for the past few years, the sun has finally set on the Post Office Jumps. Hopefully they will be relocated and rebuilt, but before they were torn down riders including Jeff Herbertson got in one last session…


Asterion’s F-One Cross Country Wheelsets Roll Out at Sub 1200G

2015 Asterion F-One Wheelset, 29" wheel

F-1. A simple letter and a number combination that has garnered global recognition in the automotive racing world and become synonymous with speed, performance and technology. It’s a fitting name for competition or luxury level componentry, such as these ultralight, hand-built cross country wheels from France’s Asterion.

Asterion is a small operation that assembles about 10 wheelsets a day, but the company is growing with an impressively wide selection of high-end stock and custom wheels. Their new carbon F-One wheelset should catch the eye of weight-conscious cross-country riders. According to Asterion, the 27.5” F-One wheelset weighs in at 1137g, and the 29” set weighs 1184g, not including the tubeless valves or rim tape. There are a few options to choose that might change that number, but you’re still looking at some very svelte wheels.

Find out about Asterion’s rim options after the jump…


Intense teases custom, one-off “Spider” dual slalom full suspension for Shaun Palmer

prototype intense spider dual slalom full suspension mountain bike for shaun palmer

Put together just for their newest factory rider, Shaun Palmer, this one-of-a-kind dual slalom bike from Intense could be making its competitive debut at the Sea Otter Classic. But that’s not all they may introduce at the world’s largest consumer bike expo…we hear the junior development DH team will announcing the new team members, too!

First things first: The frame looks to be based on their mid-travel Spider full suspension mountain bike, but with geometry specified by Palmer. It was then fabricated by Jeff Steber and made into a frame by Rick the Welder. Wheel’s are 27.5″, with parts from sponsors DT Swiss, Maxxis, SRAM, Fox and Renthal. While’s pure speculation on our part, we’re thinking he might just be taking this thing out on the dirt on Sea Otter’s extremely spectator friendly slalom course.

In January, Intense opened up the application process for any licensed DH racer between ages 15-17 to earn a spot on their new team, which Palmer will help shepherd to podiums. Intense’s marketing manager told us “Palmer is sponsoring his own Junior team this year. Sponsors are Intense (of course) and many others. We plan to do a media launch and introduce the team and sponsors at Sea Otter.”

Reworked iSSi Pedals Offer Improved Release Angle, SPD Compatibility, and New Colors

Issi pedals trail xc new springs (5)

First introduced at Frostbike 2014, iSSi was back at Frostbike 2015 with a reworked line up offering better performance across the board. For the first go around, iSSi pedals would work with SPD cleats, but they weren’t a perfect match. Good news for anyone with multiple bikes that already have Shimano SPD pedals, the new iSSi pedals are all SPD compatible offering a much better feel when used with SPD cleats. The improvements don’t just apply to SPD cleats however, as the guts of the pedal have been redesigned to offer better function and feel with the included cleats from iSSi.

Of course color is a big part of the iSSi story as well and there are a few new options like the blingtastic gold pedal above…


Vee Tire Adds More 27.5+ Sizes, Introduces White Fat Bike Treads

Vee Tire Co 27+ white fat bike tires (1)

Just under a year ago, we caught wind of the first 27.5+ offering when Vee Tire Co. informed us that their Trax Fatty model would soon be available in a 27.5×3.25″ model. Looking around the show there were a few generic bikes fitted with the new tire size, but nothing that would have suggested it catching on in a big way. Now, headed into Taipei show and Sea Otter season there still aren’t a ton of options but it seems like the tide is swelling.

Originally planning just to offer the 27.5×3.25″ size, Vee is introducing two more widths to round out the line. Meant to fit better in smaller frames, Vee sees the Semi Fat market exploding in the coming year…
