Jonathan Vaughters' Slipstream team continues to carry a heap of momentum
heading into next season. In addition to the recent run of high-profile
rider signings (which include David Millar, David Zabriskie, and Tom Danielson),
the team has just announced a new sponsorship agreement with recently
acquired Zipp Speed Weaponry to utilize the company's wheelsets through
the 2009 season.
The agreement will be old hat for Zabriskie, who rode Zipp wheelsets
during his stay at Team CSC, but will be a marked change for Millar and
Danielson, who most recently have used Mavic and Bontrager/Hed products
during their 2007 seasons with Saunier Duval-Prodir and Discovery Channel,
According to Zipp president Andy Ording, "Team Slipstream's approach
represents the future of professional cycling both in the U.S. and in
the European peloton. We are thrilled to be aligned with the team and
we are confident in their ability to represent Zipp well. Most importantly,
our relationship with the team will extend beyond sponsorship to provide
us with a constant stream of input that will help shape our product development
through technological innovation."
Slipstream Team Director Jonathan Vaughters added, "We're a team that
must search out every legal advantage we can find. Having wheels that
genuinely test faster in the wind tunnel and have been race proven give
us a legal edge, which is what this team is all about."
Trek slims down the TTX
Trek reportedly shaved 300g from
the standard Equinox TTX

Trek's new 2008 Equinox TTX 9.9SSL reportedly shaves a sizeable 300g
off of last year's standard Equinox TTX 9.9 model through the use of aggressively
machined aluminum fittings and a more advanced OCLV Red carbon fiber content
and lay-up schedule. A switch to SRAM's new Red componenty group is also
said to lop off an additional 150g as compared to the current version's
Shimano Dura-Ace package.
Thankfully, Trek has retained all of the aero trickery featured on the
TTX, though, including the wider fork leg spacing which is claimed
to save 0.1lb of drag in comparison to the narrower spacing of more typical
aero forks, internally run cables that enter the frame behind the stem,
and a sculpted fork crown which blends more seamlessly into the lowered
According to Trek, recent trips to the San Diego Low Speed Wind Tunnel
showed that its TTX frame design was more aerodynamic than other reference
machines in 'real world' conditions, utilizing fully built framesets and
identically positioned riders. In addition, Discovery Channel team captain
Levi Leipheimer supposedly posted the lowest total drag figure ever recorded
by a male athlete at SDLSWT back in February 2007.
Trek will offer the Equinox TTX 9.9SSL in three sizes as either a bare
frameset or a complete bike outfitted with a Bontrager Aeolus 5.0/6.5
wheelset, a SRAM Red drivetrain, and a plethora of Bontrager Race XXX
Lite components for US$8249.99. Other Equinox TTX frames will use either
OCLV Black or OCLV White carbon fiber blends and less expensive componentry
at price points down to US$3079.99.
Avanti Bicycle Company adds JetStream technology to its time trial frames
Avanti Bicycle Company claims its
new Chrono frameset

John Cobb's original
JetStream carbon aero fork admittedly looks a bit odd, but the unique
split-blade design supposedly diverts air away from the churning front
wheel, thus smoothing overall air flow and decreasing aerodynamic drag.
According to Oval Concepts, who currently markets and distributes the
JetStream, the design can shave a substantial 55 seconds per hour at 50km/h
as compared to conventional forks. That sort of time savings naturally
hasn't gone unnoticed by some top ProTour contenders, either, including
Gilbert Simoni, Damiano Cunego, and most recently, Cadel Evans, who used
it to help achieve his second-place finish at this year's Tour de France.
New Zealand bicycle company Avanti already equips its current Chrono
time trial/triathlon frame with a special version of the Oval Concepts
JetStream fork that places the brake caliper behind the crown, but has
now integrated the split-blade design into the carbon seat stays of the
2008 Chrono. According to Avanti, recent tests conducted at San Diego's
Low Speed Wind Tunnel have shown that the new split stays can save nearly
a full minute off of a one hour time trial, roughly doubling the advantage
of the fork alone. Avanti will also equip the new Chrono with an exclusive
version of the JetStream fork for even more time savings.
"We have a burning desire to make faster bikes and were looking for innovations
to enable that," said Avanti Group Product Manager Kim Struthers. "We
had the idea which we knew hadn't been tried before and consulted Morgan
[Nicol] at Oval who agreed there could be significant benefits of integrating

Respected British framebuilder Terry Dolan has seen riders claim Olympic,
National, and World titles aboard his frames (both under the Dolan livery
and otherwise) and will finally see his creations available on US soil.
DPM Sports, the US distributor for the Spanish Spiuks and Kuips lines,
plans to offer a comprehensive range of Dolan machines covering road,
TT/triathlon, track, and cyclocross disciplines.
Among the new offerings are the 2008 Scuro, a 920g frame which utilizes
a full Dedacciai carbon tubeset, the integrated seatmast-equipped full-carbon
Aeolus, and the slippery Aria TT machine which is reportedly favored by
none other than Cofidis star Bradley Wiggins. According to DPM Sports,
cyclocross frames will arrive the first week of November, just in time
for the season, while road frames will follow just a couple of weeks later.
The full Dolan inventory is reported to be available the following spring,
and interested dealers can contact DPM Sports directly at firstname.lastname@example.org.

Italian disc brake manufacturer Formula has issued a voluntary recall
on certain members of its Oro
brake family. All Oro brakes manufactured before July 2007 with master
cylinder serial numbers 295237 and lower are affected; some 2005-2006
Oro Puro models, however, may not be affected as they use a different
According to Formula, the recalled brakesets utilize a set screw to secure
the pin that affixes the brake lever. If the screws are not properly torqued,
the pin can fall out and the brake lever will become inoperable.
Affected owners are asked to immediately bring the affected brakes to
a Formula dealer for inspection and/or repair. Alternatively, users may
also follow the repair instructions posted on Formula's web site. Additional
information can be found at www.formulabrakeusa.com.
