2014 Cannondale Road Tandem 2
There has been a recall on the fork for this bike and other 2014 cannondale tandems - make sure to check your bike has the new fork fitted. See recall info here
The new 2014 Cannondale Road Tandem 2 is now in the shops. We bought one a couple of weeks ago and have been out for a couple of rides on it.
I have posted some pictures and info here
The pre-speculation about the new Cannondale tandems can be found in the "New Cannondales Coming" thread.
There were a couple of questions about the bike on that thread.
- Weight: I haven't been able to weigh it yet
- Largest tyre: It came with 25mm 700c tyres. There is a good amount of clearance on the fork so you could fit bigger if needed. Have a look at the pictures (I took some with a tape measure to help)
- Rack fitting: Not sure - have a look at the pictures as I am not sure if the fittings are for a rack or a mudguard.
2014 Cannondale Road Tandem 2
It's very similar to our 2010 RT2, although the fork appears different. The 2010 came with their "Fatty" fork, which appears more tubular, although with similar clearances. I've even considered mounting 2" knobbies and taking it off-road.

The cantilever bosses, as shown, should allow us to add aux brakes if we need them for descending. And yes, it has mounting points at the top of the seat stays and on the dropouts for a rack. The Axiom Transit rack fit perfectly with no mods necessary, except a little flexing of the legs.
We're currently running Gatorskin 28s at 90-95 lbs, and have little to complain about ride harshness, although we haven't ridden enough other bikes to compare. Just calling out the bumps as I see them. And so far, their bulletproof.
Tire pressure and bent rim walls
I realize that this discussion has gone to sleep a while ago, but I came across it as I was looking for info on the DT 535 tire pressure (I just had a Cannondale road tandem delivered, and was pretty surprised by the low maximum pressure).

My Mavic X317 rims stated a maximum pressure of 7.7 bars for 1" tires and 3.3 bars for 2.3" tires. Inflating the 26x1.6 tires to 5-6 bars was apparently well beyond this limit, as it eventually led the rim walls to bend outwards (yes, it was a bad idea to check only the recommended tire pressure and ignore the rims).
It may therefore generally be a bad idea to exceed recommended rim pressure, but the limit should be seen in relation to the tire attached. A 35 mm tire will generate more rim wall stress at 5 bar than a 25 mm tire, but it will also give better suspension at a given pressure. I find it hard to believe that the apparently solid DT 535 rims will have trouble handling 25 mm tires inflated closer to 7 bars, and as the technical document you supplied indicate that they are intended for 1"-2.35" tires, I assume it will be safe to inflate mine at least to 7 bars. Thanks for sharing!
