Speedplay originally intended its recently debuted Light
Action pedal for first-time clipless pedal users and cyclists that
generally fell more towards the recreational end of the spectrum. Surprising
sales figures, however, have prompted the company to actually expand the
range upscale with the introduction of stainless steel and even titanium-spindled
versions, all available in four different colors.
Based on rider feedback, Speedplay identified three key performance metrics
for clipless pedals: effortless engagement, secure attachment, and easy
exit. According to Speedplay president Sharon Worman, "When we introduced
the Light Action, people loved them because the pedals do these three
things. But then they told us they wanted two more things: stainless and
The new Light Action Titanium version will retail for US$305, while the
stainless steel model will draw US$175 from your coffers. Suggested retail
on the chrome-moly version will remain at a very reasonable US$115.

Although it still stands by fully integrated setups, Indiana-based Zipp
Speed Weaponry acknowledges that they don't always deliver the positioning
flexibility that some riders want or need (and often are out of reach
for many in terms of budget). In response, Zipp expands its aero arsenal
with the introduction of its newest Vuka Bull base bar which should offer
plenty of independent adjustability when paired with clip-on aero extensions.
The full-carbon Vuka Bull is built using similar layup schedules as on
Aero, along with a similarly minimal frontal area, surprisingly comfortable
end 'pods', and internal brake cable routing (although brake levers are
not integrated into the design as on the Vuka Aero). Claimed weight for
the sole 42cm-wide offering is just 195g, making it among the lightest
base bars on the market.
Suggested retail for the bare Vuka Bull is US$325, while a US$580 kit
will also include Zipp's Vuka
Clip and a pair of extensions.

Chris King debuted a new 150mm ISO rear hub at the recent Downieville
Classic in Downieville, CA. Specifically aimed at downhill and freeride
users, the new hub features Chris King's trademark micro-engaging RingDrive
internals, signature custom-made stainless steel sealed cartridge bearings,
a 19.5mm constant diameter axle, and an aluminum hub shell available in
either 32-hole or 36-hole drillings and the usual rainbow of colors.
The new hub will work with standard 12mm thru-axle frames, and stainless
steel drivers will be available as an option. As with all current ISO
hubs, bearing preload can be adjusted with a 2.5mm hex wrench without
wheel or rotor removal, and the hub will carry Chris King's usual 5-year
Claimed weight with an aluminum driver is 336g, and the suggested retail
is US$369.99. The stainless driver option raises the price slightly to

Italian helmet maker Limar joins the 200g helmet club with its new PRO
104, said to weigh as little as 180g for the medium size. Claimed to be
"The World's Lightest Helmet" (Specialized may have something to say about
that with its new sub-200g S-Works 2D), the PRO 104 is based on Limar's
now-classic F104 model with a sleek appearance and low-profile fit.
The PRO 104 also boasts an in-mold shell and Limar's Pro System retention
system. Twenty-two vents that promise good ventilation in hot conditions
(something the riders of the TdF are all-too familiar with currently),
and the new helmet will be offered in two sizes.

sports performance testing facility at its Austin, TX headquarters. The
impressive equipment list includes one of only five SRM ergometers, a

made in the lab, and the acquisition of equipment of the caliber of the
SRM, ParvoMedics and Woodway platforms underscores our commitment to providing
the finest tools and resources possible for facilitating the success of

of sophistication that we have deployed and we know that this level of
commitment is required to achieve the results we demand of ourselves in
