[PICS] 2015 Felt IA Triathlon Bike - Design Features and Specs

"Whether you’re looking for an aero advantage on the road or your next Ironman leg, you gotta check out the new bikes from Felt." - Bikerumor.com



Last year, Felt introduced its top-end, brand new IA bike. The bike came in only one version, designated FRD. FRD of course stands for Felt Racing Devlolpment, and it is reserved for the highest level of technology that has been in development for the past 5-6 years. Labeled as a no holds barred approach to bicycle design, the first FRD product was the 9 hardtail which also was the fist use of Oxeon’s spread tow carbon fiber. Team Argos Shimano has been riding an F Series FRD, Sarah Hammer has been winning on her TK1 track bike, and the FRD F series has been raced in Paris Roubaix.

Felt Bikes Mountain Road 2014 (32)This year, Felt is releasing no fewer than three new builds, which use lower-grade carbon, but feature all of the same integration and features as the original. These are styled the IA2 (Di2 and Novatec carbon clinchers), IA3 (SRAM RED 22 and carbon clinchers), and IA4 (Shimano Ultegra and alloy clinchers). Finally, the frame that makes up those less-expensive builds will also be available separately, and is called the IA1. Personally, that one is my favorite, featuring an incredibly-slick black-and-nude paint scheme.

The "lower-grade" carbon in the new frames isn't exactly a pedestrian material. Felt is still using industry-standard materials, including medium and high-modulus unidirectional fabrics on interior layers, and a beautiful 3k weave on the surface layer. Personally, I actually prefer the look of the 3k surface layer of the new frames versus the very large weave pattern of the TeXtreme on the FRD frame. But what does the high-end FRD frame buy you? Basically, it saves a few grams. Felt tuned the layup of the new frames to match the performance of the FRD, but the spread-tow characteristics of TeXtreme allow that frame to use fewer layers of carbon to achieve them.

Possibly one of the most interesting features of the AR and IA is their newly patented seat post design. Aerodynamic seatposts can be big improvement in the performance of a frame, but they have a serious drawback – clamping.

Felt 2014 Launch080613_0895 Felt 2014 Launch080613_0896


Instead of clamping around the post, both the AR and the IA have a slit that runs up the middle of the post. Inside the seat post there are two plates that are threaded, and tightening the two seat clamp bolts pulls each clamp from the inside to expand the post against the inside of the frame. This accomplishes two things, it clamps the post effectively so it doesn’t slip, and it allows for the post to be constructed so that it actually improves the ride over a round seat post. To give you an idea of just how much different the construction of the post differs, you can actually squeeze the post with your hands and get to two sides to compress slightly. According to Felt, the previous seatpost design was 470 times stiffer! Each post has a silicone strip that is used to keep gunk out of the inside of the post, and there is also an adapter for securing a Shimano Di2 internal battery to the bottom of the clamp pieces.

The IA is a born-and-bred tri bike. It comes stock with 52-36t chainrings, slightly lower gearing than the average time trialist might use. Every version of the bike is smartly-equipped with an Adamo Attack, the most popular aftermarket saddle there is. The bike has slightly higher "effective" head tube height compared to the older DA and B2 frames, by which I mean that the minimum stack height to the pads is just slightly higher. It can still get very low, but not quite as low as the DA with the 0-rise stem. The higher stacks are trending throughout the industry, with Cervelo, Specialized, and others all increasing their tri-specific head tubes and minimum stack heights in general.

Another tri-specific feature on the IA is its integrated top tube storage. The rubber cover has been revised this year to make it a little easier to install, and also improves cable routing, introducing a cable port that is available with or without the cover installed. Check out our followup article from inside Felt HQ (in "Related Articles" below) for more on the evolution of the IA storage unit.

Felt 2014 Launch080613_1015To improve the aerodynamics on the AR, a new proprietary brake was designed which felt claims offers the same performance and feel as a Dura Ace brake. The stopper is hidden under a two piece cover, which is removable to easily work on the brake unlike integrated units. The brake will also be offered on the Bayonet 4 equipped DA which uses a one piece cover instead. The brake is a simple roller cam design, with a cable the pulls from the center to actuate the two arms which are equipped with TRP pads and pad holders.



Felt 2014 Launch080613_0882The rear brake is also covered in a shroud, though there are cut outs to adjust the pads without taking off the cover.

Designed primarily for electronic drivetrains, the IA hides the battery in a compartment just in front of the rear wheel in the seat tube.
 
Like most tri bikes, the IA has horizontal dropouts that are adjustable for different tire/wheel combos.

2015 BMC Bikes (3/3) Gran Fondo GF02 Carbon


BMC’s Endurance Series is topped by the cobble-bashing GF01 and GF01 disc, but the previously alloy GF02 has been superseded for 2015 by a new all-carbon frame and fork. 

 (article from BikeRadar.com/BikeRumor.com)

The same characteristics built in to help the GF01 carry pro racers from Paris to Roubaix – higher stack, shorter reach, longer chainstays, relaxed head angle for greater stability and control with less fatigue over time – are just as relevant to riders who like to challenge themselves, but want a bike to give them confidence and help them through long days.
Using GF01 moulds, identical shapes and geometry, the GF02 has a new carbon layup, with thicker carbon plies resulting in some added weight but reduced cost. Claimed weights for a painted 54cm frame and frameset with all hardware attached are :
  • GF01 : frame 995g / frameset 1,705g
  • GF02 : frame 1,250g / frameset 1,975g
The new model is UCI compliant, electronic compatible, includes an integral chain catcher and the same carbon seatpost as the GF01. BMC’s testing has shown comfort values, torsional stiffness and bottom bracket stiffness between the GF01 and new GF02 to be the same.

There are six frame sizes : 48, 51, 54, 56, 58 and 61cm, and three component specs – Shimano Ultegra, 105 and Tiagra, which also comes with 10-speed 105 levers. All come with compact cranks, Shimano wheels, 28mm Continental rubber and Selle Royal saddles.

Also offered are a 105 (left) and Tiagra builds. All come with their full carbon Compliancepost, which works in concert with the TCC frame and fork to improve overall comfort. It comes standard with an 18mm offset, but 3mm and 30mm offset posts are also available. Frames use their DTi cable routing, which means it works with both mechanical and electronic groups even though mechanical shifting cables are run externally. All three bikes spec durable Continental Ultra Sport 700×28 tires and have an integrated chain catcher, both of which should help keep you on the road and out of the shop.

Summer Is Here! Are You Hydrating Properly?

Depending upon you sweat rate and the weather, you lose anywhere from 1 to 2 quarts of perspiration an hour. 


On rides, you must replace this fluid loss with more than just water because you're not only losing H2O, but also vital nutrients. Energy drinks are best because they contain the electrolytes and nutrients lost through sweating


Energy drinks also provide carbohydrates to fuel the muscles. But it's got to be an energy drink you enjoy because if it tastes good, you'll drink more. And, if it tastes bad, you won't drink enough, if at all.


When you're carrying energy drink in both bottles, lower the concentration in your second bottle because as you fatigue and heat up, you'll likely prefer less flavor and sweetness. If you're riding hard, it's also important that your energy drink isn't too concentrated. Too rich a mixture can upset your stomach and even slow down or prevent water absorption.

Preparing for a cycling event or race? Be sure to experiment while training to find the drink that's most compatible with your system. That way, you'll be drinking something that works and you won't experience stomach aches or cramping during the important ride. Also, train with bottles and hydration packs to determine which works best. The latter are great for long rides because of their large capacity. Plus, the hose makes it much easier to drink enough. So on bumpy terrain such as in an off-road race/ride they can offer an advantage.


To make sure you're properly hydrated before an event, check your urine. It should be pale yellow or clear. Dark yellow and strong-smelling urine is a reminder to drink a few more glasses of water, although vitamin pills can have a coloring effect as well. Another key sign of proper hydration is having to get up during the night before the event to urinate.



When the temperatures start soaring, insulated bottles and hydration systems can keep your water cooler, which will help keep your body temperature lower. You can also freeze water in your bottles the night before. But, fill only half way so you can top it off with drink before the ride. The ice in the bottom will chill the liquid for a while. Ice in a hydration pack can also help cool your torso.

2015 BMC Bikes (2/3) Speedfox MTB

"Built for Riders Looking for a Light, Versatile Bike with a Relaxed Position"



With successful cross-country and all-mountain ranges already well established — and sponsored rider Julian Absalon seemingly addicted to winning and gunning for the 2016 Olympic title — BMC extended its investment in 29in wheels. Internally dubbed BWC for Big Wheel Concept, the concept employs short chainstays, slack head angles, generous top tube lengths, short stems and minimal stack height. For consistent ride feel, they even spec the same stem length on all bike sizes within each model.
The Speedfox defines BMC’s new Trail Series, pitching it at riders looking for a light, versatile bike with a relaxed position, that gives confidence without being unduly complicated to set up or maintain. The Speedfox, BMC says, is ideal for those who can’t ride every day, but want to make the most of precious weekend trail time with a bike they can just grab and go.

The Speedfox is a 130mm travel bike that occupies the chasm between Fourstroke and Trailfox. Borrowing the 435mm chainstays and 68.5 degree head angle of the Trailfox, the balanced geometry has 607mm stack and 435mm reach (size M), but is still slack, with an offset fork. Stem length is 70mm across the range, and the frame allows for up to six internal cables and hoses, entering the frame on either side of the head tube, covering all control options. The drive-side chainstay also incorporates a chain guide and protector plate to save the rear triangle from damage.

The range consists of three models — SF01, SF02 and SF03 — each available in five sizes, from XS to XL. The SF01 has a full carbon frame and comes in two specs : XTR or XX1. SF02 has a carbon frame and alloy rear triangle, with three specs : XO, XT or XT/SLX. SF03 is an all alloy frame, offered in two specs : XT/SLX or Deore.

2015 BMC Bikes: (1/3) Team Machine SLR03

Newest BMC Team Machine (SLR 03) Boasts Similar Tech To Higher-End SLR 02

(from roadcyclinguk.com, pictures from pelotonmagazine.com)

Like The SLR 01 and SLR 02 released in the last year, the design of the 2015 BMC SLR 03 has been developed with ACE (Advanced Composite Evolution) Software. Computer simulations generated 34,000 virtual frames in 355 days, from which fewer than five different configurations produced comparable figures for the stiffness of headtube and bottom bracket, and compliance. From these, prototype frames were built in Grenchen for testing by Evans, Gilbert, and Van Garderen.



The new design process resulted in an SLR01 frame that was 25-percent torsionally stiffer across the entire bike and 10-percent laterally stiffer at the bottom bracket. The frame also had 10-percent more vertical compliance. Overall the SLR01 saw a 50-percent improvement in its stiffness to weight ratio over the 2012 SLR 01. Once the SLR01 was complete BMC applied the ACE technology to the slighter heavier SLR02. For 2015 BMC has again trickled down the technology to the new SLR03.



The SLR03 is offered in three specifications, including the new 11-speed, 5800-series Shimano 105, Shimano Tiagra (with 10-speed, 5700-series 105 STI levers), and Sora.

Shimano wheels are specified with each machine, with the 105 model rolling on the Japanese component giant’s RS11 hoops, while its Tiagra and Sora-equipped siblings are equipped with the budget R501. All are shod with Continental’s Ultra Sport rubber, in a 23c profile that now looks dated, despite the SLR03’s intended application.

At the top of the three-strong SLR03 range is a machine partially equipped with the new 5800-series iteration of Shimano’s popular 105 groupset. The chainset, however, is the RS500, equipped with compact ratios, while the brake is the non-series R561- a dual pivot unit equipped with cartridge pads.

The Tiagra-equipped model lives up to the billing, and even exceeds it with the aforementioned, 5700-series Shimano 105 lever, while the Sora bike appears as advertised, with a full deployment of Shimano’s second-from-bottom group.

All three are finished with a Selle Royal Sirio saddle, and aluminium bars, stem, and seatpost branded with BMC logos.

Keep on the lookout this week for more information about other new BMC bikes!

New Zipp 404 Firestrike Carbon Clinchers

Zipp 404 Firestrike Carbon Clincher Wheels Review


Loaded with refinements, the 404 Firestrike sits above the Firecrest wheels, which remain in the range. As you might have guessed from the small name change, the Firestrike indicates a different rim profile but one that still uses Firecrest technology and is covered under Zipp’s existing patents. The re-profiled rim is now wider by roughly 1mm all round. Giving a total width of 26.4mm at the widest point of the brake.
This wider profile has further advantages in that as Zipp found with its original wider profile the rim is less susceptible to sidewind forces steering the wheel for you, part of the new profile aim was to reduce this still further – something Zipp claim to have done.


Sitting in parallel to this is that they’ve also reduced the side force the wheel experiences in cross winds by a whopping 34%. A good proportion is because of the wider rim but they also looked at the dimples that have come to characterise Zipp rims. By looking again at dimple size and spacing, the Indianapolis aerodynamicists have tuned the dimples to shed air vortices more frequently, which also contributes a worthwhile amount.
Thanks to the wider brake track, the tyre now sits more squarely on the wheel giving it a larger footprint and increasing grip but as there is less flex in the carcass of the tyre, rolling friction is reduced at the same time.
