Which Suspension Fork for my Cannondale?
 
We've got a 2004 Cannondale Mountain Tandem.
We are new to tandeming this year, but love it and have decided to upgrade our bike.

I'd like to have decent travel but maintain reasonable handling.
Also I want to be safe and be sure that the fork I buy will not snap.
(I've done this on normal bikes, very scary)

I'm 175lbs, stoker is 115lbs. We ride fairly aggressive singletrack.

Any recommendations on what type of fork to use on this bike?
How much travel?
Steel or aluminum steerer tubes?
Is a thru-axle necessary? (I will need a new front wheel, is it worth it?)

I'm thinking a 100mm travel dirt-jumper (DJ 2 or an Argyle 302) but any advice is appreciated!

Thanks!!!

First piece of advice - contact Alex Nutt at www.mtbtandems.com. He will be up on the latest and has probably built more bikes than anyone else out there.

That said, I run a DJI on my ATB tandem. Captain weights 190 lbs, stoker 95 (#1 son). We ride reasonably aggressive, too. The advantages of the Marzocchi are high rate springs are available and the air assist allows you to set it up for tandem weights.

I am a firm believer in the thru axle...I use Magura Gustav M brakes with 200mm rotors (hey, you're stopping >350lbs bike included) and watched the previous fork (standard dropouts) flex under the load.

Who is nursing a broken right hand (hockey injury) and won't be riding for a couple days....maybe I can get a stoker to captain....

That bolt on axle is a must if you are using disc brakes. and I would suggest MTB Tandems .

I use a Rockshox Boxer Fork. Full downhill but this is one of the older ones with 150mm movement. Much more than that is Going to give you a pogo stick. Had to get the heaviest springs they make and also put in the sag adjusters to the max to cut a bit of movement. I use 20 wt oil and slightly over fill aswell to cut the movement. They may be an MTB fork but for us they work. We do ride aggressively and still get full travel on the downhills but if you want 50mph offroad downhill- then you need a fork that will take the punishment. These will.
