PROPULSION IS POSSIBLE
Zipp is in the business of helping people win races, and some people use smaller
wheels. So Zipp scaled down their classic 900 to the Zipp 840 Disc Tubular
Bicycle Wheel to accommodate 650c riders who are just as worthy of a disc that's
wickedly fast, freakishly light and offers an incredibly smooth ride. Now that
you're on an even aero-playing field, the competition better look out.
Recommended and approved
These brake pads have been tested and approved by Zipp for use with their
tubular and all carbon clinchers. Failure to comply with these recommendations
could negate your warranty.

With the new Firecrest rim shape in Zipp’s 404 and 808 Tubulars and Carbon
Clinchers, Zipp wheels make a bigger difference in more ways than ever. Not only
is Firecrest more aerodynamic than any other rim design, it improves handling in
crosswinds, wheel strength, and overall ride quality.
Boundary Layer Control) - Advanced Boundary Layer Control (ABLC) refers to
the patented and instantly recognizable dimpled pattern found on most Zipp rims.
ABLC smoothes airflow across the rim's surface and is tailored to every model
from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up
to 4 times more dimples than before.
Constrained Layer Control) - Visco-Elastic Constrained Layer Control (VCLC)
uses a vibration-absorbing material sandwiched between layers of rigid carbon
laminate in the rim. When the wheel receives an impact from the road, much of
the shock is absorbed by the VCLC system, delivering a 10% reduction in
- Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets
of carbon to each other in Zipp’s tubular rims. Because Kevlar is 350% more
impact resistant than carbon, it can disperse shock more evenly throughout the
carbon laminate, making for a rim that is practically bulletproof. In
particular, Carbon Bridge reduces the vulnerability of the rim's tire bed, the
area most susceptible to damage from impact.
