All-New Diamondback Serios Triathlon Bike Proves Thinner Isn’t Always Faster

2015-diamondback-serios-tt-triathlon-bike

Teased just before all the top triathletes headed to Kona for Ironman World Championships, the new Diamondback Serios slipped some very interesting frame shapes in and out of focus with a short video. Now, we’ve got a very in-focus look at one of the sharpest looking tri bikes in recent memory and some Q&A with DB’s product manager to make sense of it all.

The story is they started with thinner and thinner tubes, thinking a more waif-like structure would slice through the air quicker and easier. What they found was some cross sections could be wider and provide better aerodynamics. And wider was better when it came to the range of riders it could fit, too. The project is a collaboration between Diamondback, HED Cycling and Kevin Quan Studios. The result is a wild looking TT/Triathlon bike that’s UCI legal and fits pros and age groupers both short and tall.

Here’s how they did it…

IB14: ISM Pads Their Saddles, Adds Triathlon Features & Recreation Models

ISM-PN1-1-and-PR2-0-triathlon-comfort-saddles

The Adamo Attack is ISM’s most popular road saddle, but some riders wanted something cushier. The new PN1.1 uses same shape but gets more padding and switches from titanium rails to steel. PN stands for Performance Narrow, and the PN1.1 will retail for $149.95. Width is 110mm, length is 270mm.

Not shown, the PN2.0 is a new triathlon version that gets a hook under the rear of the shell to hold the the bike in a ready-to-go position in transition racks. It gets the thinner, firmer padding of the Attack, making it more of a racer’s saddle.

PR is their Performance Recreation line. Shapes are similar to others but with more and softer padding. That’s what’s new, but we’ve got a look at Michellie Jones’ custom Felt race bike after the break…

First Impressions & Actual Weights: Recon’s 161g Titanium 11-Speed Road Cassette

Recon Titanium road bike cassette actual weight and early review

After testing the 120g alloy Recon race day cassette, we sent the link to Fair Wheel Bikes, not quite sure how they’d take it. After all, I snapped more than one tooth off that one and relegated it to use on the trainer. Fortunately, they appreciated the honesty and said it sounded about right, then offered up the more durable titanium version for review.

And here we are. Also made by Recon, the 6AL/4V titanium model uses two 3-cog clusters on the big end of the cassette -the largest of which sits on an alloy carrier- followed by individual cogs and spacer rings for the remainder. The 11-tooth cog is made from steel. It’s available in silver and gold, and the price is a whopping $320.

Here’s how that compares to SRAM, Shimano and Campy…

IB14: RPM2 Power Meter Shoe Insole Inserts Measure Force Everywhere

RPM2 cycling power meter shoe insole insert

While PowerTap may have experimented with insole-based power meters, RPM2 put their foot down and stepped into production.

They make versions for both cycling and running as well as a combo unit for triathlon/multisport use, and the cycling features make it fairly unique among power meter options. Garmin’s recent software update for its Vector pedals added a simple foot pressure balance measurement, showing if you were putting more pressure on the inside or outside edges of the pedal. Presumably, this data let you know if you’re feet could be better centered over the pedal for more efficient power transfer.

RPM2 takes this a step further (or closer?) by measuring both left/right and fore/after pressure, letting you see exactly where your feet are pressing the hardest against your shoe’s sole. This provides more specific and exact data that can be used to correct cleat placement, fit and alignment.

Of course, it also provides standard total power output for each leg, along with cadence and where in your pedal stroke your power is being applied…

Found: CyclingCeramic Bearings from the Pro Peloton – Bottom Brackets, Jockey Wheels & More!

cyclingceramic-premium-bearings-derailleur-jockey-wheels7

The pros are an interesting bunch, always looking for any little edge they can get. Sometimes it’s aero, sometimes it’s nutrition and sometimes it’s just making the parts they’re already using work better. For the latter, CyclingCeramic says half the pro peloton at this year’s Tour de France turned to their bearings for their wheels, bottom brackets and/or derailleur pulley wheels.

Shown above on official partner IAM Cycling’s team bikes, you’d also unofficially find them on at least four more of the largest, most well known teams’ bikes, too.

What makes them special? They start with high quality ceramic balls, then polish them for 45 days to enhance the smoothness and roundness, which minimizes surface contact area. Then, they use a tougher, lighter polyamide carrier to position the bearings between the races. For the bottom brackets, which see higher forces than the other parts, they developed a special hardening process for the races to improve durability, overall smoothness and resistance to corrosion. Lastly, they developed their own seals that maximize the “fluidity” of the balls’ movement inside while keeping contaminants out. It’s all hand assembled in France in their own facility, so they have control over the final product. Roll on for product pics and options…

Closeup: New FSA ITC Seatposts Offer Flip Flop, Independent Angle and Offset Adjustment

2015 FSA ITC seatpost design weights and specs

Introduced at Eurobike, FSA’s new ITC (Independent Top Clamp) seatposts are wrapping up production and first batches should be hitting FSA’s warehouses soon.

The design uses a rounded base for the top clamp section to adhere to, allowing it to rotate through a wide range of angles completely independent of your saddle rail position. Even better, the top clamps are available in two versions, giving you a total of four offsets: 0, 10, 15 and 20mm, and in any direction you want. If your seat angle’s not too steep, that’s effectively seven different positions from a single post!

They’ll be available in alloy and carbon versions with 27.2 and 31.6 diameters. Click through for full specs and weights…

EB14: Campagnolo Bora Wheels Gain Clincher Options

2015 Campagnolo Bora Ultra and Bora One carbon clincher road bike wheels specs and weights

This summer, Campagnolo’s top level Bora wheels were redesigned to be wider, lighter and have better braking performance. But they were still tubular only, as has always been the case for that model.

But even Campy admits not every top rider wants to deal with glue or the risk of being stranded (or carrying the spare and paraphernalia to use it). So, they’ve finally introduced a clincher version with the same options. Choose from 35mm or 50mm depths and Ultra or One trim levels. Both use a 24.2mm wide (UPDATE: 17.4mm internal width) rim with the 3Diamant braking surface they say offers equal stopping performance to alloy rims. Wheelset weights are around 200g more than the tubulars, and you can catch all the tech and closeups below…

EB14: Corima’s Full Carbon Spoked Wheels Get More Aero, Plus Updated Internals & More

2015 Corima MCC full carbon spoked road bike wheels

Corima’s MCC carbon spoked wheels get new hubs and the front wheel gets new, flatter spokes. That makes it a bit more aero at the leading edge of the bike, but the rear keeps round spokes to be stiffer since fewer gains were to be had there. The pic above shows the transition from round at the hub to flat for the majority of their length

The front hub is a little sleeker, without as much flare from the shell to the flanges, reducing the overall frontal footprint. They also switched it from woven to UD carbon, just like the rear…

Stage Race to Offer Custom GT Edition Scapin Ivor, Plus 2015 Ceepo Line

Scapin Ceepo Stage Race ivor etika mamba viper 2015 (5)

Ever ridden a production bike and wished you could just make a few tweaks that you felt would make it the perfect bike? Stage Race has. When you work closely with a bike company both distributing and selling their product, sometimes you have the opportunity to voice those desires and in the case of the Scapin Ivor, the result is the new GT Edition.

The crew at Stage Race loves fast bikes, but they are also fans of slightly larger tires and a bit more relaxed geometry. Situated as the high end bike in the Scapin line up, the Ivor previously offered only race ready geometry and fairly tight tire clearance. The new GT model provides a new option for the Italian carbon marque along side the standard and full custom options…
