It is well known what all wheel drive does for a sport utility vehicle — just imagine what AWD can do for a mountain bike.
With increased traction, available at the flip of a switch you can conquer conditions that you thought were unridable. AWD 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 AWD system is so efficient, it is hard to tell whether it is working… until you need it.
With the front drive disengaged, the CHRISTINI AWD handles and feels just like any dialed-in full suspension Mountain Bike. Engage the AWD system and you’ll feel increased control, stability and traction on slippery or loose surfaces.
AWD 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 AWD is equipped with standard mountain biking components. Pedaling, shifting and braking are just like on a traditional bike.
A handlebar-mounted switch controls the AWD “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 AWD 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 AWD is simply the best climbing mountain bike on the market with the amazing downhill benefits too. When a front end tucks, the wheel stalls, stops turning, and begins to push. With the AWD system, as soon as the wheel begins to stall, power is delivered to the front wheel, forcing it to turn. With the front wheel under power, it is nearly impossible to wash out the front end.
With added up hill traction and downhill control, you’ll be amazed at what our bikes can do!
The CHRISTINI AWD 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.
