Product Highlight – Jagwire Barcon 2.0 Shifter Mounts

  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.

    Hello, I am working on making a pair of these work for my bike. For Shimano style lever shifters do I need a flat spacer in-between the lever and the Barcon or does the lever mount right next to the Barcon with the little plastic thing that comes with Barcon? If you have any photos showing better interface of system I would be super in debt. I also realize this post is kinda old… Thanks!

      Hi Devin!
      These are really cool looking, aren’t they!
      (…I’ve been eyeing them, too!!)

      Although I have not actually handled the these Jagwire barcons, (based on these photos) I certainly believe they are exactly the same shape as the Shimano Dura-Ace bar end shifters (SL-BS77, SL-BS78, SL-BS79). Therefore, you would NOT need additional hardware, and you could simply transfer your standard levers, bosses, and bolts.

      Also, remember to shift your levers into the down (shortest cable) position before removing them. It will insure all the internal bits remain aligned & properly synchronised, plus your cables will correctly set when you are reconnecting your derailleurs

      Good luck, and HAPPY CYCLING!!
