Cervelo P5 Fairing = Disqualification

Posted in News, Uncategorized with tags , , , , , , , , , , on June 15, 2012 by hypercatracing

Well boys and girls it looks like our little discussion has paid off.  USAT officials and Cervelo management have met to discuss the issue chronicled here and thanks to Cervelo being made aware of the issue have stated their case with a positive verdict.  After discussion with Cervelo and a thorough review of the issue, USAT has been able to rule that this device does not fit the “functional definition of a ‘fairing’ and only as a dust/debris cover for the brake calipers.”

Below is the original posting of the rule violation.

 

 

Earlier this year Cervelo launched to much fan fare it’s hotly anticipated P5.  Among the numerous technological advancements are a new Magura brake system.  In the non UCI compliant version Cervelo has chosen to add a snap on cover that shrouds the front brakes and this is where the problem lies.

From a a communique sent out to USAT officials (which is how I found out) USAT officials are now to look at the Cervelo P5 and see if the cover is in place for the front brake.  If it is, they are sighting that rule 5.11 (3) – look below –  applies and the penalty if not removed is disqualification. fortunately for P5 owners the covers simply snap off, but it is still an issue that you cannot use all the bells and whistles when competing in an UCI, ITU, USAT or national championship cycling, triathlon or duathlon event. Hopefully when Cervelo goes into full production they will address the fairing issue, but for now it looks like the P5 will have a prominent feature that is unusable in most events.

 USAT rule 5.11 (e) reads: Aerodynamic carriers for food, water, and or cycling provisions may be attached to or be an integral part of the aero handlebars if they meet the following guidelines: (including There must be no protective shield, fairing, or other device on any part of the bicycle frame, wheels, handlebars, chain wheel, and accessories) which has the effect of reducing resistance.

Product Highlight – Jagwire Barcon 2.0 Shifter Mounts

Posted in New Products, Uncategorized with tags , , , , , , , , , , on December 13, 2010 by hypercatracing

  I was given my first set of Jagwire shifter mounts in 2007 as a beta set for testing.  These Originals only worked with Shimano shifters.  The concept of the shifter mounts was simple; create a mount that replaced the traditionally very heavy Shimano shifter base.  To lighten the load Jagwire took the internal expander wedge and threw it out and made the system an external mounting system.  This not only significantly reduced weight but had the side benefit of solving the problem of bars with different internal diameters and bars that had been modified beyond the ability to mount a shifter internally, safely.   Yes, I have cut quite a few bars down in the name of aerodynamics, only to later ponder how to mount the controls.  Oops.  Now I plan ahead before modifing.

Tech: BarCon 2.0      

  • SRAM® and Shimano® bar end shifting systems
  • Weight: 44 grams per pair
  • Housing: 4mm derailleur housing w/ L3 liner
  • Housing Length: 2100mm
  • Cables: Slick stainless, SRAM® & Shimano®
  • Cable Length: Front – 2300mm, Rear – 2300mm
  • Small Parts: 4mm sealed alloy ferrules, donuts & tips
  • Other: Shims for 22.2mm bars

Shimano’s traditional mount weighs ( 47 grams each ), while the Jagwire replacement weighs only ( 22 grams each ) That’s a savings of 52 grams, or basically one shifter.  Couple this with adjustiblity in mounting and you have a great bang for the buck at $59.99   with cables/ housing.  The current version, known as 2.0 allows the same bracket to be used with either Shimano or SRAM.  Currently there is no Campagnolo version.  With this simple adapter Jagwire’s engineers came up with an ingenious solution that solved the compatibility issues and made it possible to use the same mount with both SRAM® and Shimano Shifting Systems. I have tried both now, and they seem to work equally well.  Another side benefit because of the design these can work on road bikes as well, so for cyclo-crossers that use bar-end shifters or touring bikes this is a great way to shave some additional weight and add in some flexibility to shifter location. 

        

 From Jagwire’s description.

The BarCon’s sleek low profile design shaves precious grams off the weight of a bicycle and its external mounting is adjustment and service friendly. And the external mount makes the BarCon very versatile. While originally designed for triathlon bikes the mount can be used in a variety of applications including H-type handlebars, touring style drop bars and recumbent bike handlebars.

As a side note:  I recently broke a left (front) Sram lever on my TT bike and was able to slap on a Shimano shifter as a replacement without changing my set-up, pretty slick. 

Pro’s: 

  • The system is easy to install
  • Shifters can be placed at any angle regardless of bar angle/ positioning
  • Very lightweight
  • Comes in 3 anodized colors (Black, Gold. Silver)
  • Can be used to quickly convert a road bike to tri bike
  • Works great for Cross or Touring bikes

Con’s:

  • Only works on bars with round tubes
  • Does not work with shaped, integrated aerobars  
  • External routing

Overall, the Jagwire 2.0 Barcon mounts are simple, well constructed and easy to install.  They come with a new set of shifter cables (stainless) and Jagwire’s best L3 housing.  I ride with my bars sized so that when aero my shifters are in the palm of my hand, with this position I found the jagwire shifter mounts to be slightly more comfortable than the Shimano and even more comfortable when compared to the SRAM (not a huge fan of the step down center with SRAM). 

Bar compatibility:

  • Will work with any standard round metal handlebar
  • Will work with any round metal aerobar (all brands)
  • Will not work with some carbon round bars (ex. Profile Cobra)
  • Will not work with aeroshaped carbon bars (ex. Profile Viper, Volna)
