Interbike 2006:


Sinister Bikes

Sinister had a very smartly designed new bike for the coming year on display. It’s not quite ready for production but the Passion will be quite the machine when it’s released. The Passion will use “Variable Suspension Technology” which allows for a “natural” vertical wheel path plus an “on demand” rearward path. What makes this design special is that it takes the positives from both rear path designs and vertical path designs and puts them together to form a its suspension system. What this means is that it functions much like a Morewood Izumi or Orange 224 on sharp hits (taking them very fast) but has the pedal performance of vertical wheel path design. The VST system also uses a dual spring rate to deal with initial suspension movement and handle upward and downward movement seperately. For more information, pics, and specs check Sinister’s website.

Passion

“The wheel travels vertically over small bumps, but when more suspension is needed, the wheel moves backwards too. This means the stays are short for sprinting when the suspension’s supple, but square edge bumps are taken care of when needed.”

Normally the swingarm sets flush against the bottom bracket but as the bike takes a sharp hit such as a big rock or a curb the swing arm moves backwards as well as upwards to take the hit.
