Christini background

In the summer of 1994, Steve Christini went out for a mountain bike ride and came back with an idea. It had rained earlier that day making the conditions a bit slippery, though nothing that many riders don't face on a regular basis. After losing traction on his rear wheel a couple of times Steve, a senior Mechanical Engineer at Villanova at the time, started thinking: why not power both wheels?

After a few sketches and a lot of thinking, it came to him: an internal drive shaft to the front wheel. Seems pretty simple, right? To make a longer story short, Steve, along with co-inventor Mike Dunn, made this their senior design project and turned a lot of heads. Several years, tons of sleepless nights and some great stories later, here we are.

Christini Technologies, Inc., located in Philadelphia, was formed in June of 1999 and is now the world's leading developer of All-Wheel Drive Mountain Bikes. Each member of the Christini Team lends their own special qualities which gel together to create a truly unique company that brings to you the next great innovation in mountain biking.


Christini All Wheel Drive

It is well known what all wheel drive does for a sport utility vehicle - just imagine what All Wheel Drive can do for a mountainbike. With increased traction, available at the flip of a switch you can conquer conditions that you thought were unridable. All Wheel Drive provides greater control over wet roots and slippery rocks. You can power up steeper, sketchier hills and you'll stick like glue to side slopes.

The All Wheel Drive system is so efficient, it is hard to tell whether it is working... until you need it. With the front drive disengaged, the Christini All Wheel Drive handles and feels just like any dialed-in full suspension Mountain Bike. Engage the All Wheel Drive system and you'll feel increased control, stability and traction on slippery or loose surfaces.

All Wheel Drive works whether you're pedaling or coasting. You will be able to descend with confidence and corner more aggressively due to increased front wheel grip.


How it works

The Christini All Wheel Drive is equipped with standard mountain biking components. Pedaling, shifting and braking are just like on a traditional bike.

A handlebar-mounted switch controls the All Wheel Drive "shift on the fly" clutch. When the clutch is engaged, the rear spiral gear interlocks with the rear hub and power is transferred via internal shafts to the forward spiral gear set, which drives the Christini freehub.

Due to a slight gearing differential, the front wheel is not actively powered on smooth level ground. However, the moment the rear wheel slips, power is instantaneously transferred to the front wheel. Similarly, the moment that the front wheel decelerates, as in hitting a rock or starting to wash out in a corner, power and traction are transferred to the front wheel.

The effect is awesome. Instead of stalling when the rear wheel slips - the front wheel hooks up and you keep climbing. Instead of glancing off a slippery root - the Christini All Wheel Drive tracks right over it. Instead of washing out the front end in an off-camber corner - the front wheel literally chews it's way through the turn. The Christini All Wheel Drive is simply the best climbing mountain bike on the market.


Durability

The Christini All Wheel Drive has the capability to take you places other bikes won't or can't follow... and the durability to get you back.

In over 4 years of testing, the AWD components have required far less routine maintenance than the primary drive train (which is comprised of top quality sprockets, high-end shifters and standard hubs). The best corrosion and wear resistant materials are utilized and we have "designed in" extremely simple service procedures. For instance; should the sealed bearings ever need to be replaced, the entire internal drive system can be disassembled for complete overhaul in less than 10 minutes.

* There is a 5 year warranty on the frame, a 2 year warranty on the entire all wheel drive system, and a one year crash replacement warranty on any Christini drive system parts.
