Boo Bicycles Testing Carbon Fat Bike Rims for Alubooyah Upgrades

prototype boo bicycles fat bike rims for alubooyah

Spotted at the Philly Bike Expo aboard a team rider’s bike, these carbon fat bike rim prototypes are getting put through the paces for a Winter 2015/16 release.

The design comes from the supplier, not from Boo Bicycles, but CEO Nick Frey said there’s a lot to like about them, revealing a few interesting notes about fat bike carbon rims. For these in particular, he says they’re reasonably light, between 500g and 600g per rim, 80mm wide and set up tubeless very easy.

The have a double wall construction, so they’re stiff and strong, too. It’s here that some of the construction gets interesting. He said because the tires are so big and provide so much cushion between the ground and the rim, the carbon rims haven’t needed the same level of impact resistance as a carbon rim designed for normal mountain bike tires. So, they’re able to use less expensive, lower quality carbon to save cost without sacrificing performance or durability.

The plan is to offer them sometime next year as an upgrade option on complete bikes, but we see no reason they couldn’t be offered as a standalone aftermarket part for any fat bike you may own. Closeup pics below…

Review: Birzman Maha Apogee MTB High Volume Floor Pump

Birzman maha apogee MTB pump review fat bike high volume (2)

Earlier this year we started hearing about fat bike specific pumps. On the surface that sounds ridiculous, until you consider the mechanics. Bicycle tires offer a crazy range of volumes and pressures from 200 psi track tires to 5 psi fat bike tires. Yes, there are pumps that will do both, but if you’re the kind of person who wants the right tool for the job there are better options.

The Birzman Maha Apogee MTB is a mountain bike specific pump. What does that mean? It means the pump is purposely designed to push a lot of air as quickly as possible. Placing the focus on high volume instead of high pressure, the Maha Apogee MTB and pumps like it becoming more and more useful as tires continue to trend larger.

After getting our hands on the Maha at Eurobike and proceeding to inflate fat bike tires on the show floor, and even a flat tire on Cory’s car, we’ve had the pump long enough to give it a thorough review….

Kona Issues Recall of 2014 WO Fat Bike

wo

If you own a 2014 Kona Wo fat bike, the company is reporting that you should stop riding it immediately. The recall is due to the potential for the fork to break where the steerer tube and fork crown meet which could obviously cause a crash. There has only been a single incidence of failure without injury at this point, but that is enough for Kona to issue a recall which will affect around 531 bikes equipped with the Kona Fat Project Two Disc Fork.

Wo owner should stop riding the bikes and contact their local Kona dealer for instructions on obtaining a new fork.

Eurobike Awards 2014: Road, Tri, Mountain, City, and of course, E-Bikes

eurobike awards bike (10)

If there was one bike in the awards area at the show that epitomizes the idea of a design award, it would probably be the Rafael r-023 Ueberbike. From the driveside it may be easy to overlook if you’re not into tri bikes, but as soon as you take a glance at the non-drive side of the bike it stops you in your tracks…

Bike Check: Jeff Herrera’s La Ruta Winning Borealis Yampa, Courtesy of Dirtwire.TV

Borealis Yampa La Ruta

I bet you never expected to see a guy on fat bike wearing a leader’s jersey. That’s exactly what happened when Jeff Herrera tackled the 22nd edition of La Ruta De Los Conquistadores on his 22 lb Borealis Yampa. There was actually an entire fat bike class at La Ruta which Jeff won, but he also finished just outside of top 20 overall in 22nd place.

Our friend Thom Parsons was on hand in Costa Rica this year to ride some bikes in flip flops, take in some sun, and also provide coverage for Dirtwire.tv including more installments in his Wicked Pro Bikes video series (you have to say it with a Boston accent). After Jeff’s bike check, Thom says “This is the fat bike (and fat bike rider) who finally made me want a fat bike. ”

PBE14: Santana Goes Really, Really Big with Cirque Fat Bike Tandem!

Santana Cirque fat bike tandem prototype mountain bike

The great thing about smaller shows like Philly Bike Expo is the laid back atmosphere, where we have time to hear the stories behind more than just the latest and greatest. Last time, Santana’s owner, Bill McCready, gave us a fantastic materials science talk. This time, he had less to say, mainly because this monstrous bike was built in his absence.

Santana leads group tandem tours overseas. On their last trip, while they were nonchalantly letting participants play around on the BionX equipped e-tandem shown at the bottom of this post, his employees were busy welding together this prototype fat bike. The expo was the first time anyone else had really seen it, and it was hard to miss…

PBE14: Wild Paint & Graphics from Bells Bike Shop and Groovy Cycles

bells-bike-shop-hydrodipped-camouflage-alchemy-road-bike03

Bells Bike Shop is based in Philadelphia, PA, with a big presence on eBay, too. To corner their booth, they hung a custom made and custom “printed” camouflage Alchemy road bike.

The camo graphics are a water transfer process known as Hydro-Dip, which essentially coats the object in printed designs just like the stickers on model airplanes used to be, just bigger. Once dry, the frame was clear coated, which made any seams very hard to see and impossible to feel.

Slide past the break to heck it out close up, followed by an out of this world martian space scene on Groovy’s fat bike!

45NRTH Slaps Winter with a Sturmfist, Introduces New Extreme Winter Cycling Gloves

Sturmfist_4_GL1806-04

You’re familiar with the Cobrafist, now lay your eyes on the new 45NRTH Sturmfist line. Built to help you give old man Winter the finger while keeping said finger from getting frostbite, the Sturmfist gloves take a decidedly 45NRTH approach to winter gloves. The rise of fat bikes means a lot more people are braving the cold and are willing to pay for better cold weather cycling gear – as long as it works.

Many winter gloves are labeled as simply, winter gloves. The Sturmfist gloves are tiered based on what temperature ranges you expect to encounter, either 15-35ºF, or for the more robust winter pedalers, 0-15ºF. Labeled as the Sturmfist 4 or Sturmfist 5 based on the number of fingers, though both look to offer a good amount of dexterity considering their temperature ratings.

While these should be great for other winter activities as well, the Sturmfist gloves are purpose built for cycling thanks to a first among cycling gloves…
