Trek founder passes away at age of 73
Trek Bicycle Corporation founder Richard 'Dick' Burke passed away Monday
evening in a Milwaukee, Wisconsin hospital at the age of 73. Burke had
apparently been suffering from a heart ailment and died as a result of
complications after a recent heart surgery.
Trek is currently run by Burke's son, John. Cyclingnews would
like to extend its condolences to Burke's family and friends as well as
the rest of the Trek Bicycle Corporation.
Barloworld sets out on new Bianchi time trial bikes

In addition to its fleet of new Bianchi road machines, Barloworld riders
now have proper time trial rigs from the heralded Italian company as well.
According to Bianchi product development manager Lars Svalin, the all-new
D2 was conceived with a balance of rigidity, weight and aerodynamics in
As such, the head tube, down tube and chain stays are dramatically oversized
while the T-shaped top tube and spindly seat stays are pared down for
weight savings. The chain stays also bear unique pass-through ports that
supposedly further improve rigidity by adding surface area.
Up front, the bladed fork is equipped with a long trailing crown to help
ease airflow transition to the down tube and the deep-profile seat tube
includes a close-fitting cutout for the rear wheel. Bianchi specifies
the D2 with a 76 degree seat tube angle but an adjustable head for the
integrated design will allow for substantial fore-aft movement to accommodate
both time trial and triathlon applications.
Claimed frame weight is 1350g; the matching fork is said to be 450g.
Rock Shox set to debut revamped Reba; Avid expands color palette

The Sea Otter Classic is rapidly approaching and with it will come a
fresh crop of new gear. SRAM is already offering up a teaser of what's
to come which will apparently include a thoroughly revamped Rock Shox
Reba chassis. Among the new features is a new Maxle Lite 20mm thru-axle
system which will boast the same easy-to-operate functionality as the
original but 50g lighter courtesy of a slimmed-down aluminum axle, alloy
hardware and a pared-down lever. We'd imagine that Maxle Lite will be
an option on the new fork in addition to standard 9mm quick release dropouts.
SRAM MTB media/PR manager Eric Schutt was cagey on additional details
but did mention that we should expect to see some decidedly SID-like features
on this newest Reba. More significantly, though, Rock Shox currently has
no plans to adopt the 15mm thru-axle standard recently introduced by Fox
Avid will also expand its color palette a bit for the Juicy Ultimate
(and perhaps other models?) to better coordinate with its presumed SID
pairing. New colors will include the previously team-only white as well
as SID blue.
Karbona expands operations ahead of 2008 Taipei trade show

Taiwanese carbon components manufacturer Kabrbona has expanded its range
and reach for 2008 ahead of the Taipei Cycle Show. In addition to its
existing track frames and broad component range that includes bars, stems,
seatposts, saddles, cassettes and other items, Karbona now adds a range
of mountain bike, road and time trial frames and forks to its product
line. Karbona expects distribution throughout Europe initially and full
bikes expect to run US$3500 to US$4000.
Karbona is also adapting some carbon-and-aluminum component technology
to frame tubes. By wrapping a light and thin aluminum tube with carbon
layers, Karbona says the new tubing combines the benefits of both materials.
The handmade system supposedly yields high tensile strengths and Karbona
reports that it has already produced frames using the method.
Everti debuts new titanium 29er

After a full year of design work, British Columbia titanium specialist
Everti has added its first 29"-wheeled mountain bike to its stable. The
aptly named '29R' features a double butted top tube and seat tube for
reduced weight and a livelier ride while the rest of the frame utilizes
straight-gauge stock. The down tube is bi-ovalized for strength and rigidity.
In contrast to what many 29er builders are doing these days, Everti actually
chooses to go with a slightly longer head tube to better distribute
the stress of the longer fork. A small gusset adds further reinforcement.
A decision to use full-length housing shields the derailleur cables from
contaminants common to Everti's locale.
Claimed frame weight is 1500g and Everti will offer its new 29R in medium,
large and extra-large sizes to suit riders from approximately 1.7m (5'
8") to 1.9m (6' 4") tall. Other sizes will carry an additional US$200
custom fitting fee. Suggested retail price for the frame only is US$1595
and Everti will also offer complete builds.
Baum introduce Corretto model

Australian-based custom bike company Baum has introduced a new model
to its range of titanium frames, the Corretto. The bike was unveiled at
Melbourne's Motor Show, where it has spent the past two weeks on display
at the Volvo Cars Australia stand.
"Volvo have supported cycling over a long period, and have worked with
us over the last four years," said company owner Darren Baum. "Launching
the bike at the Motor Show seemed like the natural thing to do, and a
good way to say thank you to Volvo for their support."
The Corretto is one of the few titanium frames to feature individually
butted tubes throughout the frame. This includes the chain stays and seat
stays, and even the head tube and bottom bracket shell are CNC machined
to be thinner in the low stress areas, and thicker in the welded areas.
"It really came about because customers who already had one of our Ristretto
titanium frames were looking for that bit extra in terms of ride quality
and weight reduction," explained Baum. "As soon as the first frames were
delivered, we were amazed at the feedback we got in terms of ride quality
and overall performance. From that point onwards we've been pushing to
make the Corretto part of our regular model range."
Baum has continued its unique quirk of naming each model in its range
after a coffee recipe, with the Corretto being a short black coffee with
"If you've ever drunk grappa, you'll remember it for a while afterwards,"
explained Baum. "We wanted to make a frame that would be just as memorable,
but was a little easier on the legs, and on the head."
The Corretto frame and fork is priced at $6,995 AUD, including a Tune
Bobo headset. While each Baum is built to customer's individual requirements,
the complete 6.1 kg, SRAM Red-equipped model on display at the Melbourne
Motor Show was priced at $14,400 AUD.
3T to debut new seatpost head design at Taipei show

3T continues its return from the dead with a novel new seatpost design
dubbed Palladio. According to 3T, the Palladio's new DiffLock head offers
true rock-solid security while still delivering half-degree tilt increments.
DiffLock will also offer truly independent fore-aft and tilt settings.
The heart of the DiffLock head consists of two pairs of concentric and
interlocking toothed rings that are concurrently engaged within the toothed
inner surface of the top of the seatpost. It sounds more difficult than
it looks (at least on paper) and the design looks to be rock-solid as
promised. However, actually making those tilt adjustments requires one
to at least partially disassemble the head.
We'll work on getting a test sample in the near future but we're intrigued
for now. For those riders who have had issues with loosening posts in
the past, this may very well prove to be the solution but we'll let you
know for sure in due course.
Sportful unveils new Total Comfort shorts
Sportful aims for comfort

Italian cycling apparel maker Sportful says its new Total Comfort shorts
were designed with one major objective in mind (two guesses): comfort.
Ultrasonically welded seams are used throughout the Lycra Power body but
the bib straps are completely seamless and littered with laser perforations
for improved airflow. Mesh inserts are also used at the back and sides
while the leg openings are fitted with Sportful's elastic-free 'Paradise'
system in lieu of conventional grippers.
Sportful also outfits the new short with a seamless Total Comfort stretch
chamois. The new insert is fitted with triple density padding, an antibacterial
Meryl Skinlife microfiber topsheet and is perforated up front for airflow.
