AbsoluteBlack Teases 40-Tooth Cassette Cog

AbsoluteBlack 40-tooth cog for converting to wide range 1x10 cassette

The OneUp 42t cog got quite a bit of attention, and seems to be working out pretty well for Zach after a few tweaks to the rear derailleur. But, AbsoluteBlack founder Marcin thinks he’s got a better solution.

In development for a couple months now, his 40-tooth cog works the same way as OneUp’s: You remove one of the middle cogs to make room for a larger one at the top. The most superficial difference is that it uses two less teeth, which he says eliminates the need to tweak the B-tension screw. In theory, this means the expanded gear range comes with no major adjustments outside of the cassette.

There’s more to it than that…


Factory Tour: Hero Bike’s DIY Bamboo Bicycle Workshops & Semester Carbon/’Boo Campaign

Hero Bike Factory Tour storefront

We’ve written about Hero Bike a couple times now, first to showcase their Semester bike Kickstarter campaign, then about their build-a-bamboo-bike workshops and kits. Over the Thanksgiving holiday, we took a detour from our Greensboro, NC, office to their Greensboro, AL, shop to see how they make the bikes and kits from locally sourced bamboo. And by local, we do mean local. All of their bamboo comes from within a five mile radius of the shop. They grow some on their own land and harvest it from locals’ properties.

Hero Bike was started by the HERO group, a community program originally developed to give at-risk youth something productive to do and, now, as a job training program. Indeed, Mike Gillis, the sole hero present on Thanksgiving Eve found out about the job but had to apply through AmeriCorps to get it. It’s one of several businesses under the Hero umbrella, and their neighbor business assists with the DIY bike building kits that ship out to home tinkerers.

The two bikes they build here -the pencil shaped Semester and the DIYers- couldn’t be more different, showcasing an entirely new way to make bamboo/carbon tubes…


FastDad and Cola Wheat are Back, This Time with a Stunning 80g SRAM Red Derailleur

FastDad SRAM Red 80g derailleur light weight tuned (1)

The duo responsible for turning ordinary derailleurs into highly functional, light weight works of art is back. This time with a tuned SRAM Red derailleur, ironically in all black. You may remember the team from our last post where we showed off their incredible 64g Shimano Dura Ace derailleur. While their latest Red creation isn’t as light, it is just as beautifully machined and tuned down to the last gram.

Curious how you remove 53g from an already impressively light rear derailleur? Check out the details after the break!


Student Creates Amazing Wooden Campagnolo Derailleur

Wooden Campagnolo Derailleur Front

Over the years we’ve showcased many components and frames crafted from an array of unusual materials, but nothing like this fully functioning wooden Campagnolo derailleur has ever graced our front page.

Created by woodworking student (or should we say artist) Max Hoffman, this wooden sculpture is one spring and some mounting hardware short of earning a handmade bamboo bicycle top honors at NAHBS.

Predator Cycles Takes One-Piece Majors Handlebar-Stem Combo to the Trails

Predator Cycles The Major one-piece carbon fiber handlebar and stem for mountain bikes and Cannondale Lefty fork

We first spotted Predator Cycles at NAHBS in Denver, where they showed The Major, a carbon fiber combination of FSA stem and road handlebars to create a massively stiff one-piece unit. Those are done by creating a huge triangle of carbon from the base of the stem that spreads about 3″ out either side.

The mountain bike version, however, eschews the huge triangulation in favor of a sleeker, more forgiving setup that realizes a good carbon bar assists in muting trail chatter. This particular one was made for Sergio Hernandez, one of Predator’s Pro riders that raced MTB in the off season. Founder and builder Aram Goganian says it comes in at just around 270 grams with the stem. Typically, he builds with FSA components, but the Lefty stem system is a little more custom.

Bikerumor’s Definitive Guide to Cycling Themed Halloween Costumes For Procrastinators

ET Halloween Costume

I’m a consummate procrastinator. In fact, I’m probably procrastinating something right now! If you fit the same bill, here are a few stupid Halloween costumes  that you can quickly put together in a pinch. We’ll start it off with the trickier costumes and get progressively easier.


Ignore how well put together this costume is. This girl had enough time to carefully craft E.T.s ugly dome out of paper mache but you’re on a tight schedule. To put this outfit together on the fly, substitute the alien with a hasty sketch done in sharpie on a poorly cut piece of cardboard. Swaddle in a white cloth and duct tape to a spare set of handlebars or basket…Just don’t use this Hail Satan Rack. It might prove dangerous in a confined setting.

Head past the break for the rest of our spook-tacular costume ideas…


Kickstarter: Store your Bikes in the Roost with the Bike-Nest

Whether you have 1 bike or are approaching S-1 (S being the number of bikes owned that would result in separation from your partner), bike storage is always at a premium. So California based engineer, Robert Ozarski, has created a slick new bicycle storage system which vastly improves upon existing pulley systems.

The Bike-Nest attaches to your ceiling via two bolts and uses a spring mechanism to raise your bike sky high. Much like a properly functioning set of window blinds, a slight tug on the cable brings your bike to ground level. You can also stop the bike in any position as it descends, which means the Bike-Nest could also double as light workstand.  READ MORE ->

IB13: Keener Cycle Works 36″ Mountain Bikes – Lefty Fork, Dual Front Disc Brakes & Legos!

Keener 36 inch wheel mountain bikes with Lefty fork

Found parked outside the XtraCycle tent were two 36″ wheeled monsters from Keener Cycle Works.

UPDATE: At present, there’s no website, just their Facebook page, so we made contact to get the scoop. Just got in touch with Bryan Keener Smith and updated the post with comments and info about the bikes. He’s been making frames for a bit more than 30 years, since he was about 19 years old. The first 36er started about seven years ago but took a while to reach completion. His full time job is building telescope assemblies – he says he can’t build bikes fast enough (he’s too meticulous) to make it a livable venture.

The bike above featured a custom integrated Lefty fork, and the other, which you’ll see further down, had dual front disc brake rotors, Legos and more. Roll through…


Hack! Retroshift x TRP = Drop Bar Hydraulic Disc Brakes w/ Friction Shifters

Retroshift friction shifters on TRP Hylex hydraulic drop bar road bike disc brakesClick that pic to see it full size you’ll notice something a bit off. It took us a few seconds to fully appreciate the hack.

See it? Yep, that’s the new TRP Hylex hydraulic disc brakes that are intended for singlespeed bikes mated to a Retroshift friction shifter, providing a geared setup and modern brakes for a fraction of what a dedicated SRAM or Shimano system would cost. Especially if you mate it to their BURD rear derailleur.

Nick’s been reviewing the Retroshift and likes it. And those brakes felt really good at Interbike’s outdoor demo.

Retroshift’s founder Adam Clement told us he’s been talking to TRP about it for a while, just been too busy to make it happen. He says it “requires brake lever disassembly, fixturing, drilling, etc.” This prototype’s been a work in progress for a while, with this bike being built up by Sellwood Cycles, and will be raced this weekend. Plans are to make it a stock offering for 2014.
