Transition TR500
The TR500 is the successor to both the TR250 and the
TR450, and features adjustable geometry that lets riders build it up in
multiple configurations. Everything from a mini-DH / bike park ripper with 180 mm
of travel all the way to a downhill race bike with 203 mm of travel is possible, and adjustable
chainstays allow the bike to accommodate 26” wheels.

Constructed from hydroformed 6.061 aluminum, the TR500's frame has a modern, low slung look, aided by the fact that the linkage that drives the rear shock is hidden inside the split seat tube. In addition to the two shock travel positions, there are chips in the rear dropouts that can be flipped to set the bike up with either 434 or 442 mm chainstays, although 27.5” wheels can only be run in the 442 mm position. The bike's head angle and bottom bracket height can also be altered by flipping the chip that's located where the seatstays mount to the rear shock linkage, giving riders the option of choosing between a 63 or 63.5° head angle and the corresponding -10 or -4 mm of bottom bracket drop.
Like its predecessors in the TR range, the TR500 uses a
link driven single pivot suspension layout. The Whistler Bike Park is the ideal
place to rack up the vertical while testing a downhill bike, containing a wide
variety of runs featuring everything from seemingly endless jump lines to
trails brimming with roots and rocks that are challenging aboard any bike. Even
at slower speeds on tighter, twistier trails the bike was quick and lively,
diving in and out of corners without any sluggishness.
Geometry and frame design play a large role in how a bike
feels on the trails, but on a downhill bike suspension is also of the utmost
importance, especially given the high speeds at which obstacles need to be
dealt with. The combination of the TR500's Fox 40 FLOAT in the front and a DHX
RC4 in the rear felt extremely well matched, working together as a cohesive
unit to filter out those brake bumps that can wreak havoc on unprepared hands
and forearms. Although air sprung forks like the 40 have become more prevalent,
especially among downhill racers, the same can't be said about rear shocks.
Component
check:
1. Shimano Saint
brakes: It's hard to
go wrong with Shimano's Saint parts group – everything from the brakes to the
rear derailleur are well designed to hold up to the rigors of DH riding.
2. Transition HD wheelset: The TR500 rolls on Transition's house brand
wheelset, which uses 32 hole, aluminum rims laced up with a 3 cross pattern to
a set of sealed cartridge bearing hubs.
Ribble Evo-Pro Carbon
Ribble is an internet bike store
with its own brand of bicycles. The
frame has quite racy geometry with a slightly sloping top tube.
The carbon forks are attached to a
steel steerer, which means there is a nice secure star nut used to tighten the
stem rather than a carbon bung. The inward curve of the seat and chainstays
make the bike very attractive looking.
Astonishingly for the price of £999 the bike is specced with the full
Shimano Ultegra 6.800 special edition double groupset.
The bike build gives you a choice of
three cassette sizings, as well as three choices of chainset. The seat pillar
can be upgraded to carbon for an extra £19.
The wheels are standard Rodi Airline
5 clinchers. A nice touch on the
Fulcrums is the spoke nipples are red to match the frame.
The saddle felt quite hard but its
shape lends itself well to support the sit bones and it still felt comfortable
on an 80-mile ride. Out of the saddle the bike felt very easy to steer and
extra pressure on the pedals was instantly transformed into speed. The two
trims on the front mech saw the chain run smoothly and quietly.
Unbelievable, unbeatable
value for money. A perfect first race bike or fast sportive machine.
About Cove Bikes
In 1992, after years of North
Shore testing and riding, Cove Bikes emerged to release the
world’s first North Shore freeride bike. The riding, testing and torn bagskins
didn't stop.
Today, Cove Bikes is an integral part of the North
Shore scene. No
wonder Cove is a four letter word to other bike brands.
Cycling NZ Unveil Revolutionary New Olympic Bikes
Cycling New Zealand has
unveiled bikes they believe will have a
revolutionary impact on the Rio Olympic velodrome. Since the track team's
two bronze medal haul at the London Games, local investment has helped research
and develop sprint and endurance bikes to advance their 2016 cause.
Working in secret, Cycling New
Zealand combined with High Performance Sport New Zealand, manufacturers Avanti,
wheelwrights Southern Spars, aerodynamic experts Kinetic Simulation and
Auckland University's wind tunnel in an effort to produce track bikes capable
of delivering gold. Bicycle design engineer David Higgins led the project for
Sheppard Industries, who market the Avanti brand.
A lot of mouths need to stay
mum. Two were Yin Fai Li and
Ben Goodwin, researchers based at Auckland University's wind tunnel in
Newmarket.
Two 90 kilowatt electric motors
power wind into the tunnel through mesh screens to remove turbulence in a
looped circuit.
New Zealand's top track
cyclists tested simulated designs at the venue. Higgins says the key thing for the sprint bike was reducing
aerodynamic drag - eventually cut by more than 15 percent - and lightening the
bikes' weight.
"We've integrated a new
handlebar design into the frame. In the past it all bolted together, whereas
this bike is one piece of fluid design.”
"With the pursuit bike,
the main design feature is the wings. They are part of a new fork design. The
fork load pass is attached to the
handlebars rather than the frame. That makes a more direct
attachment to the wheel which reduces the weight on the front.”
"Each set of handlebars is
customised for individual riders and the new design provides substantial
aerodynamic and stiffness benefits after honing in the wind tunnel."
The design team liaised with the UCI to ensure they met competition
specifications. Cycling New Zealand was allocated $17.5 million of taxpayer
money across the Olympic cycle.
