To our valued Customers, Riders, and members of the CHUMBA family:

There have been many exciting developments with CHUMBA over the last few months. But, before I get into that, I would first like to thank all of our loyal supporters and riders, and let everyone know that CHUMBA is truly on its way to becoming one of the world’s most prestigious bicycle brands in the world. CHUMBA is focused on quickly developing and tuning our suspension technology, along with offering aesthetic and performance options unmatched by any other high-end company. Here are a few of
the things we’ve been doing:

1. Identifying Suspension Curves and Accompanying Shock Settings to
Maximize Performance

To make things easy – just remember that a decreasing leverage ratio means compression resistance is increasing; and increasing leverage ratio means compression resistance is decreasing. Just remember the analogy of a lever – imagine that you are trying to compress the shock with a lever. The longer the lever is the easier it will be to compress the shock; so the more you increase your leverage ratio, the easier it becomes to compress a shock. As your leverage ratio decreases, it will become harder to compress the shock.

CHUMBA RACING NEW PRODUCT FEATURE – CANDY RED VF2 BUILD

Hydroformed top tube - no welds across top of tube for seamless shaping and molding of tube unlike monocoque pieces that need to run a huge weld on the horizontal axis of the tube often resulting in less precise alignment. Compare to older technology used by competitors:

A picture of the XTR Cassette with the 4 titanium sprockets - XTR rear derailleur - Gold Chris King hubs and Hope saw blade rotor with steel-braided cable lines. The idea of this combination is to offer unparalleled durability in conjunction with supreme performance benefits. Chris King hubs will last over a decade – and offer instant engagement for quicker traction. The XTR cassette is one of the lightest on the market – and offers stiffer titanium for higher gears.

Carbon Fiber seatstay seamlessly part of massive seatstay yoke for serious torsional rigidity of rear triangle.

Hope levers and braking system - mono m4 mated to 185mm rotors for powerful braking.
Let’s just say this bike is gonna be as fast as it looks - more detailed pics and analysis to come. You can e-mail me at alan@chumbaracing.com with any questions. Happy trails!

If the brand can be pronouced as a sneeze, this sneeze can be infectious. The VF2 will spread the virus of MTB enthusiasm.

Chumba’s story is a familiar one about mountain biking loyalists and those who pursue their dreams in the industry. The story revolves around a young man who bought a bike shop, Ted Tanouye. He began to design and sell his own DH bikes in the back of the shop. As the kid who was known to be a genius and make an immaculate product, his bikes began to gain a favorable image – also helped by some local talented and sponsored riders. In 1993 Chumba was just born… the VF2 is the latest jewel from Ted’s box, an American X Country bike - exotic and sexy.

Pragmatism

Ted long protected his own bike building – building every frame in-house for over ten years. But today, with increased volume, he moved some production to one of best builders in Asia. This is the case for the VF2. However, we have no qualms, and we are absolutely sure about the quality of this CHUMBA. It is definitely perfect.

On a pure technical side, we have a front triangle made of 7000 series aluminum, with dramatic hydroforming and manipulation. The swingarm and the four bar linkage suspension are made from carbon fiber. The suspension design offers 5′ travel, and you can use a 120 to 150mm suspension fork on it!

e…XC…eptional

With a 360mm bottom bracket high, the VF2 sits somewhat high. However, once you ride it, the Chumba gives feelings of great enthusiasm. Very stable with perfect suspension action, this bike maintains its fluidity on wet or muddy rides – as well as during acceleration and braking. You are quickly at home with this bike, and it will provide long-lasting pleasure on epic rides. Despite slightly slack angles, the VF2 steers incredibly and you can certainly ride cross-country. Thanks to the compact frame and the great four-bar design - which inspires confidence. On the climbs, the weight reminds you that you’re not on a European style XC bike. With this amount of travel, the program is more light enduro than XC French cup or marathon. However, the VF2 is not too heavy and it’s a good climber if you’re not counting seconds.

The suspension is extremely efficient and provides great tracking and bump-absorption. For the long climbs without rocks, you can always lockout the suspension with the pro pedal system, but it’s not really necessary. With the higher BB, you can still pedal even if you ride on big rocks and when the suspension works. The crankset doesn’t touch the rocks. The VF2 comes most alive on the most technical parts of the trail; this MTB has a good Californian spirit!
When you attack the descent, this bike is most in its element. It is very rigid, and you can attack without fear. No flex, this chassis is very precise. It’s comfortable on small jumps, sketchy landings, and when you ride hard-packed trails. The suspension doesn’t bottom out even on some of the relatively larger jumps we tried.

We went on lots of muddy rides, but the anodized finish doesn’t show a blemish. Note that the seat collar may not be the best, but it’s the only issue we had with the bike.
Easy, comfortable, fun, the VF2 is a bike for those who prefer finesse over raw performance.

Anaheim, CA - The CHUMBA EVO, with its patent-pending FCC suspension
will available shortly. The EVO - an extremely unique bike renown for
its proprietary suspension design focuses its center of mass under the
trunk of the rider - and channels shock input into the same area.

The EVO was trail-tested on several different continents by magazine
editors, racers, and experienced riders over the last two years and
has gained a reputation for being one of the burliest, best-handling,
laid-back and smooth-riding bikes. The EVO is now acclaimed as one of
the fastest six inch bikes available on the market for descending and
“very well-balanced” with “telepathic handling.” Read the reviews for
yourself at www.chumbaracing.com.

For this year, CHUMBA has added the following features to the frame:

1. ISCG mounts welded on the frame
2. Narrower seatstays
3. Redesigned rocker links
4. Quad bearings front and rear (totalling 8 bearings in just the
rockers) for the ultimate in lateral and torsional rigidity - meaning
no flex!
5. Direct-mount derailleur system - for ease of set-up and precise shifting.

The EVO will also be offered in several new colors: Candy Red, Candy
Blue, Candy Green, and Ano Black.
