Cannondale Fsi Q Factor

There are many solid factors that a cross country racer needs.

Cannondale fsi q factor. This is the method cannondale have used to fit the xx1 eagle crankset oem to their team bike. Do i need a new one spacers. The non driveside will require a 5mm spacer and a wavy washer or just the threaded preload ring. A gxp crankset with the wider q factor 168mm fits in the bb30a mtb 83mm bottom bracket shell with the wheels manufacturing universal bb30 pf30 to gxp adapter.

Keeps the option for a front mech and maintains the q factor of the cranks. At the back cannondale keep with the ai. The heart of the scalpel si and f si system integration is the all new ai asymmetrically offset rear triangle and drivetrain. The f si spider moves the chainrings out 6mm to match the rear triangle with no change in q factor.

The offset shifts the rear hub and driv. When the flash 29 debuted a couple years ago it brought cannondale s system integration si to the frame with things like their opi stem steerer with lefty fork and tuned save seatstays. It requires the use of a 0mm offset direct mount ring for rings 34 tooth or greater for 32 tooth and smaller you can use the 3mm offset to get chainline a little bit tighter. Your q factor will be 16mm larger.

You can run the normal range of chainrings. The spindle diameter is the same 30mm but what about the length. This enables the super short chainstays while providing ample mud clearance for the tire and maintaining double and single ring compatibility. Without affecting the q factor at the cranks.

Your crankset will be off centre in the frame towards the non driveside 3mm. Cannondale fsi carbon 1. The trouble is you need specific cranks and a rear wheel for it. I have the next sl crankset 168 q factor bolted on an orange five non boost with a 73mm bb.

I need to transfer it to a 2018 fsi which is bb30 but has a 83mm bb as far as i know. By chipps 5 years ago 0. I think cannondale factory racing is using the 168mm q factor crank and a bb with an external cup and bearing on the drive side. The chain ring is likely a custom offset.

The all new f si takes everything a step further by shifting the drivetrain off center building a new lefty a new crank spider and adding a new save seatpost to amplify the comfort of the micro. I didn t want to like a bike that requires a unique wheelset and doesn t permit you to use most cranks but it s just so much fun to ride. Cannondale has always been a master of geometry which is why we forgive the odd proprietary parts and annoyingly idiosyncratic wheel standards.
