Pedal into new Absoluteblack Ovals for the road to improve pedaling and shifting

absoluteblack-road-Oval-chainring-Ultegra-6800-Dura-ace-9000-qrings-2

With a couple exceptions around the Bikerumor crew, we’ve become oval chainring converts. While Rotor’s been at it for quite a while, Absolute Black has been pushing the aftermarket harder than anyone. And not just by machining drool-worthy components, but by making sure they have as many crankset fitting options as possible. Fortunately for all of us, they keep finding ways to improve their product’s performance.

Or, in this case, bring that performance to new segments. The new Absoluteblack Oval Road Premium chainrings follow their narrow/wide mountain and cyclocross single rings, but take a whole new approach by offering smooth shifting across double chainrings for the road…

Shimano patent shows silent ring drive hub internals that could be the next Dura-Ace

shimano scylence freehub ring drive ratchet design delivers silent drag free performance - prototype patent drawings

shimano scylence freehub ring drive ratchet design delivers silent drag free performance - prototype patent drawings

Thanks to rumor and hearsay from a Bikerumor fan and our own digging, we hear Shimano’s working on all-new hub designs. one that could offer quick engagement, more durable freehub bodies and nearly silent, drag-free coasting. And we found a few patents to back it all up.

The biggest update to their current designs is the switch to a ring drive ratchet system. DT Swiss has proven it with their Star Ratchet, but Shimano’s filing actually references Chris King’s RingDrive patent, but there’s a major difference in the way Shimano’s design moves the ratchet rings. And that difference is what eliminates the buzzing bee sound during coasting, creating quiet, fast hub that might just be the heart of XTR and Dura-Ace’s next generation hubs…

CeramicSpeed Drops in Ceramic upgrade for Cervelo

CeramicSpeed Cervelo Headset2

Do you own a Cervelo? Have you been suffering headset envy after your friends upgraded their Specialized bikes to the new CeramicSpeed? Well, suffer no more. The Cervelo compatible CeramicSpeed model is finally available. Aside from offering a more corrosion resistant headset with ceramic balls and steel races, CeramicSpeed makes big claims to the headset’s impact on front end stiffness and handling. While we’re not sure if you’ll actually be able to detect the difference in stiffness (even though they claim a whopping 128% improvement), you will probably notice headset perfection. At least, you should, given the price…

Lapierre introduces all-new Aerostorm DRS time trial bike for FDJ

Lapierre_areo-time-trial-bike_aerostorm-drs-plage

Working together with long-term sponsored French pro team FDJ, Lapierre bikes has developed an all-new version of their Aerostorm DRS. Named for the Drag Reduction System,  the bike has the singular goal of getting as fast as possible within the UCI regulations. We got a close-up look at the previous generation of the bike at last year’s Tour de France, and the new bike looks to take a big step forward in the integration game. Slip past the fold to get a closer look at how the bike gets faster, while also improving handling and braking…

SRAM RED eTap – Close up look, more rides & actual weights!

SRAM Red eTAP first rides and actual weights

SRAM Red eTAP first rides and actual weights

When we attended the official SRAM Red eTap launch last fall, we provided an in-depth look at the design and development process and first impressions.

Now, they’re closer to production, with an initial run of “P1” units ready for use in the wild. The “P1” designation, as explained by SRAM’s technical marketing manager Nate Newton, means they’re “the final preproduction run”. The idea with the P1 run is that everything: tooling, production lines, parts, are identical to production, but everything gets checked over and allocated internally rather than sold to customers.”

So, that’s what we’ve got here, in for long term testing and mounted to a Cannondale SuperSix EVO with SRAM Red 22, a Quarq power meter and Zipp 202 wheels and tires. Of course, we promptly pulled the eTap bits off and threw ’em on the scale…

PF30A to 24mm cranks – Kogel Provides Options for (even more) BB Standards, Plus Install Tools, and Narrow Wide Pulleys

Kogel Bearing Ceramic pulley 1x SRAM PF30a pf30 bottom bracket bearing drift set (3)

Kogel Bearing Ceramic pulley 1x SRAM PF30a pf30 bottom bracket bearing drift set (6)

In the pursuit of frame perfection (or perhaps patent avoidance), manufacturers are still introducing new bottom bracket “standards.” After introducing BB30A a while back, Cannondale is now selling bikes like the 2015 Slice tri bike, and the 2016 SuperSix EVO with PF30A (we’re double checking the models). That A stands for asymmetric and requires a different bottom bracket and either a Cannondale Hollowgram crank or one of the compatible FSA cranks or BB386 cranksets.

If you want to run a Shimano crank though (or any other 24mm spindle), your options are fairly limited. To address the issue, Kogel Bearings is stepping up with another version of their bottom brackets that serve as an adapter and as an improvement over the stock BB…

Review: Ceepo Mamba May Fill the Void between Road and Tri

IMG_6278

IMG_6271

One of the first real gear purchases many aspiring triathletes make is a set of clip on aero bars. Provided that they are set up correctly to fit the bike, clip ons transform your average road bike to your average road bike with an aero position. However the geometry doesn’t change along with them creating a less than ideal set up before getting into replacement seatposts and saddles.

Along those lines, something like the Ceepo Mamba could be considered the next step to Tri-dom. Finishing up the review on the 2014/2015 Mamba, it turns out to be an interesting bike that may or may not take you to your next transition…

PowerTap drops G3, GS power meter hub prices, expands Bluetooth & ANT+ connectivity

Saris Powertap Disc brake power meter hubs

2015 was a big year for PowerTap, having introduced a power measurement device for all parts of the bike. In addition to their original hubs, they introduced the P1 Power Meter Pedals and C1 Power Meter Chainring-and-Spider combo early in the year. Then they added a new disc brake version of the G3 in the summer.

Now, the G3 and GS hubs will start at just $599 beginning January 1, 2016. That’s a $190 discount off the hub itself, and similar savings should be seen on complete wheels, too. Virtually all hubs will now ship with their updated dual-band transmitter, which connects to both ANT+ and Bluetooth cycling computers or smartphones. The Dual Band end cap is also available separately as an upgrade for existing G3 and GS hub owners.

PowerTap claims a +/-1.5% accuracy rate on their hubs and, with last year’s gram reduction, a very competitively weighted way to add power measurement to your bike.

BBinfinite adding one-piece GXP bottom brackets for road & mountain bikes, explains BB tech in glorious overkill

BBinfinite-one-piece-pressfit-GXP-bottom-bracket

Look around and you might notice that more and more bikes are using the BB86 and BB92 bottom bracket shell. That’s a boon for Shimano since they’ve resisted going to a 30mm spindle, and it makes using that larger spindle that SRAM, FSA and others love more difficult to use.

BBinfinite founder Wes Wolfenbarger noticed that trend and saw another issue – bearing placement. Fortunately for him, his one-piece design solved that issue if you were running a straight 24mm spindle. But if you had a GXP crankset, which steps down to 22mm on the non-drive side, you’d have to stick with a traditional two-piece, pressfit bottom bracket. And that simply wouldn’t do.

So, not only did Wes create a complete line of GXP BB’s, increasing his SKU count by a full third, he wrote one heck of a story about how bottom bracket shells, bearings and spindles work together. Or don’t…
