Hypercat Bike Works has been building DI2 specific bikes since Shimano released the group. Master Mechanic Phil is a DI2 certified mechanic and through HBW has been involved with electronic shifting from early Suntour browning systems to Mavic’s Zap and Mektronic groups through the modern era of Shimano DI2, Campy and beyond.

This project was commissioned to take the original externally routed cabling and run all internal.  while many bikes are designed at the factory to have DI2 routed through the frame it is possible to modify most frames to accept the internal wiring with the correct choice of wiring harness.  for this bike the frame is rather large and a large kit was necessary.  Shimano offers many options and with a good amount of pre-planning and measuring the ideal wiring harness can be chosen. Due to the shape of the tubing around the front derailleur and the location of the water bottle mounts it was chosen to use a short battery mount to place on the left chainstay and an external junction box with all other elements routed internal.

For factory spec’d internal frames the Bottom bracket has capacity to route the cables around the main crank spindle.  In this case holes needed to be bored through the main BB shell.   The first hole was the main access hole from the outside of the frame through the BB shell. The second hole was the front derailleur hole mated to another port hole located at the front derailleur.   The final holes bored were the rear derailleur routing through the BB shell and through the right chainstay.  To keep the wires from tangling with the crank spindle I used two products: #1 – removed the FSA adapter sleeve and shimano BB and opted for the BB30 shell and Hawk Racing BB30.24 adapters.  This improves performance and gets the bearings further out.  #2 – added protective sleeve around crank spindle so that no moving parts are in contact with wiring if they should move around.

On the frame grommets were added to exit holes for wiring to maintain water tightness.

Front end controls were routed entirely through handlebars and stem.  Main controller mounted to top of stem and all other excess wiring tucked into available tubing.  No modifications were made to braking system other than routing cabling through stem.Hypercat Racing is a by-appointment Bike Fit studio and custom build boutique located in Ventura California specializing in aero and skinny tire bikes.

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)

If you are looking for a way to clean up your shifter position and save some weight in the process these are the product for you.  MSRP is $59.99. Hypercat December sale price $39.99 a set while supplies last, very limited quantity (black and Gold only).  Visit www.hypercat.com or this and other products, training plans or to schedule a bike fit appointment.

Get ready for Winter: 3 bike products under $10

Posted in Tips with tags , , , , , , , , on October 29, 2010 by hypercatracing

As winter looms on the horizon with cold and rainy days ahead, there is no need to hang up the bicycle, keep riding with three of my favorites products that won’t cost you more than a couple Latte’s.

  1. ProGold Voyager Chain Lube $7.99 – For nearly 12 years Progold Prolink has been my choice of chain lube.  Why, it simply works awesome.  But if you don’t believe me how about endoresments from almost every top race mechanic, Leanord Zinn, Years and years of best Lube awards from major mags and review sites, and on and on…  This year enter a new product designed to last longer through nastier environs such as winter.  built on the Prolink platform voyager is designed to not wash off with water and has a better adherence to metal too last longer between lubes.  How long,  try a rating of 100o miles between applications in normal conditions.  Talk about low maintenance.
  2. Rock and Roll Lubricants “Cable Magic” $4.00-$5.00 – This product was introduced to me a few years ago and quickly became a product I always had around.  During the winter, cables are prone to getting sticky and sluggish.  Little bits of dirt and grime and sometimes rust and make the friction between cable and housing increase and shifting/ braking performances decrease. Cable Magic reduces the friction and returns your cables to smooth operators.  After a rainy grit filled ride, drop a few drops of this into your cable housings and keep your cables running smoothly between overhauls or major services. 
  3. Jagwire Nosed Ferrules $2.99 – This seemingly small part plays a huge role in reducing the amount of maintenance neccessary throughout the winter months.  A nosed ferrule is quite simply a ferrule with a little tube added.  The little tube extends from the inside of the ferrule 1-2 cm down the length of the cable and serves as a barrier to dirt getting into the cable housing.  The picture below shows a typical application on the rear derailleur loop.  On cross and mountain bikes nosed ferrrules can be added at all housing ends to ward off dirt and contaminants and save on costly repairs down the road.  They are also available in many colors.
