Road bike racing basics,ways to increase energy in the morning,pay your debts clothing - Step 2

Rock Racing has finally unveiled their road bikes on their website, complete with specs and frame weights, but no pricing. To get that matchy-matchy look, Rock Racing collaborated with FSA and Lightweight to get some custom components.
Want to Contribute?We’re always looking for enthusiastic, positive and talented writers that know their way around both a bicycle and sentence structure. The Bura SL is a new pro-level road racing bike developed with feedback from the United Healthcare team. Other criteria were to be Di2 compatible, have a fork that was stiff enough for sprinters and without beating up the rider.
So, stiffness, comfort and lightweight were the three priorities, aerodynamics were left to the Alize, and the Diablo remains the stiffest bike, aimed at sprinters.
There are two frame models, a standard mechanical frame and a Bura SL Di2 that comes in at 760g. Where many builders use a silicone mandrel to form the tune junctions, Neilpryde uses polystyrene molds that are then burned out. This combines with the angular, ribbed headtube junction and squared off top tube to maximize steering stiffness and torsional rigidity when you’re cranking side to side. There’s a PFBB30 bottom bracket with an asymmetric seat tube to allow proper placement of the front derailleur. The chainstays are massive and designed with continuous fibers from where they meet the BB all the way through the dropouts and into the seatstays.
For the Di2 model, the battery was placed just below the lower water bottle mount, which uses the battery mount kit that bolts to the water bottle bosses. The Bayamo was first spotted at Interbike as a prototype and is designed to offer the dual package of aerodynamics and stiffness. Bike division manager Mike Pryde says the shape alone of the Bayamo does a lot to provide better stiffness numbers than those two bikes.
The lower bottle mount has three bolts, letting you run one single bottle in a lower position or two bottle in their regular positions with one on the seat tube.
From there, they improved it further by giving the seat tube a Kammtail trailing edge that carries through to the seatstays.


On the standard Bayamo, cables enter the headtube directly behind the stem, and all cables run full length housing with internal retainer to keep it from rattling.
The firm has an integrated nose cone that sits in front of the head tube and is built into the stem’s base. A TRP rear brake is integrated under the chainstays with a removable service port cover just in front of it. It has a brake plate for the rear brake, which makes removal quicker and easier. Both frames are Di2 compatible with small wiring ports and battery mounts under the chainstay, further back from the brake.
I have been following Neil Pryde’s FB page closely waiting for the Bayamo, but the build quality looks a little suspect on the Bura SL. I am not exactly a fan of the Cervelo R5 frameset, but compared to the Bura SL it looks like a beauty. The Bura doesn’t care about what people think how it looks because it only cares about winning the race.

This is a private listing and your identity will not be disclosed to anyone except the seller. Where the new Bayamo and their previous models, the Diablo and Alize (reviewed here), were designed in conjunction with BMW, the Bura SL was designed in house. They claim this allows more accurate wall thicknesses, and they place a layer of 3K carbon on the inside for additional stiffness. They say this saves a bit of weight versus adding metal inserts for battery mounting under the chainstay.
Comfort wasn’t as much of a consideration as with the Bura SL because, in most cases, triathletes and time trialists are on fairly smooth pavement. To create a fast and stiff bike, they benchmarked it against the Cervelo P3 and Trek Speed Concept.


Where most people think of the Kammtail as a flat slice through a teardrop shape, it actually refers to any truncated teardrop shape.
Riders said they wanted to be able to brake as late as possible, then accelerate hard out of the corners. This front end, including the fork, front brake and stem, could be added to the standard Bayamo anytime.
Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount.
The goal was a sub-750g frame that was stiff enough for competition yet comfortable enough for sportive riders.
Mike Pryde, bike division manager, says the bike can be ridden without the seatstays, that the chainstays are that strong.
The Bayamo ‘s trailing edge still goes to a point, but the point gets flatter as it nears the bottom bracket. The stem base will be in different lengths based on frame size, with options for people with unusual body proportions. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Throughout that process, Alumni’s Kevin Quan (a prior employee of Cervelo that worked on the P3 bike) fine tuned it using a unique take on the Kamm Tail design. Second, it creates a more aerodynamic tube shape when the wind has a higher yaw angle (ie., bigger crosswinds). Diagram above is a rough representation of the trailing edge of the tube at various points.
