Symmetry

Bar none, the Symmetry has been a mainstay in our line for many years. It's a great sports bike; good for club rides, cause rides, fitness training and credit-card touring. The 2006 Symmetry comes in a new frame material (7005 triple-butted aluminum). We've added black carbon seatstays and fork for a comfortable ride. The 19" (48cm) bicycle without pedals weighs 18.3 lbs.

The base group is Shimano 105 10-speed triple componentry (deviations from the group include an Ultegra rear derailleur and a Sugino RD-7000 triple). The rims are Velocity Spartacus with 20 spokes front/24 spokes rear in the paired spoke configuration. Shimano has added an adjustable 10-speed STI lever to their line-up this year. Combine that with the Salsa Short & Shallow handlebar, and you have a very friendly cockpit.

Symmetry follows in Isis' footprints: the 19" (48cm) size features 650c wheels front and rear. (Smaller sizes have a 24" front/700C rear wheel.) By choosing the correct crankarm length (165mm) and stem length (105 degree, 65mm), we offer a shorter, more comfortable reach to the handlebars than any other "women specific design" in this size.

This is a good time to address some riders' concerns about 650c wheels: "Will I be able to keep up with friends with 700c rear wheels?" A good question, since a smaller drive wheel is somewhat akin to a smaller gear. If you are in your highest gear on Symmetry (or Isis, for that matter) which means you are using the largest chainring (50 teeth) and the smallest cassette cog (12 teeth) and you're pedaling at 90 rpm, your speed will be 27.1 mph. At 100 rpm, your speed will be 30.1 mph. If your friends ride regularly in excess of these speeds then you may want to change your gearing. Want to play with the numbers some more?
