Zipp Rolls Out New Wheels at Eurobike

By
The Indianapolis-based folks at Zipp have been very busy lately, and they are using the Eurobike exposition to introduce the fruits of their labor to the world. 
  • We talked a little bit about this one earlier in the week, but the new Sub-9 disc wheel is said to achieve negative drag when paired with Zipp's new dimpled tubular, the Tangente2. Zipp says that it produces a negative 80g of drag at a 15 degree yam angle, yielding 11 watts of forward power. 
  • Their updated 202 wheel is as light as ever, but has seen aerodynamic improvements in the form of a different cross section, a slightly deeper rim section (32mm) and Zipp's ABLC (Aerodynamic Boundary Layer Control) dimpling.
  • The 1080 is a deep, deep section wheel that is said to be 29 seconds faster than a 3 spoke wheel over 40km. It handles crosswinds just as well as a 3 spoke wheel while being 80g lighter. 
Zipp is best known for their wheels, but they have some other, equally amazing products.
  • The new VumaQuad crankset bests Zipp's already superlight 300 crankset by 86g. It offers a huge 30mm aluminum bottom bracket spindle with an external bearing layout AND a 4 arm chainring setup that is said to be stiffer than the competition.
  • The TT/Tri fans get some new shift extensions and brake levers to go along with the very sexy Vuka base bar.
As with previous posts, as pictures become available, I'll add them to the story.

Trek Rolls Out Their 2008 Line

By
The Trek web site has been updated and now features all of their new models for 2008. They are, of course, focusing on the new line of Madones. There are 13 bikes in the Madone line including 4 "Pro" models and 3 that are designed especially for women. There are 4 ranges of carbon that are being used on the Madones, ranging from OCLV Red Carbon in the Pro line to something called TCT Carbon at the low end. I'm curious to see what will happen with the Madone line now that they are not backing the Discovery Channel team.   I really like the Portland (above), a nifty looking commuter bike with fenders and disk brakes. If I start riding home more often, one of these may be in my future. A lot of the Madone technology, as well as lessons learned from the Pro Tour, Ironman competitions and wind tunnel testing goes into the updated Equinox Tri/TT series (below).

Product Review - Specialized Rim Strips

By
Several weeks ago, while out on a group ride, I had 3 flats within the space of less than 2 hours and 25 miles. I only had one tube on me, but was fortunate enough to be riding with some very generous people that not only shared tubes with me, but also helped me put them in. One of these individuals took a look at my wheels and theorized that my flats were likely being caused by tube to rim contact, as opposed to road debris or pinch flats.  When I got home, I took off the wheels, removed the tires and tubes and took a good hard look at the rim strips. Sure enough, the Velox strips were a bit narrow, and in places, just barely covered the spoke holes.  I knew that I had to find a solution. I was tired of buying new tubes every couple of weeks. After some research on the internet, I came across these Specialized brand rim strips . I made some phone calls to local bike shops to see if anyone carried them, with no luck. I ended up ordering them directly from Specialized.  When they arri...
