Besides the Trek/Bontrager carbon tandem fork,does anyone else make a carbon fork for long/standard reach caliper brakes? I'd like to use a rim brake in the front,detest cantis,but want the ability to run fairly fat tires.I have seen a 35mm tire fit these type of calipers,and it would be nice to have the option. Having used a disc front brake,I think the right setup may be a disc rear brake and a long reach caliper front.
The Trek T2000 fork is actually quite nice. Not the lightest around, but both lighter and stronger than a Wound-Up tandem fork. The AL steerer is internally reinforced with a short steel insert at the crown, specifically for tandem use. 385 A-C, 50 mm rake; Trek part number 270946; MSRP = $250, but you might be able to talk your dealer into a lower price when they special order it for you.
Our family has two tandems made for long/standard reach calipers. I like 'em a lot. Note, however, that the QR may not open wide enough to permit passage of a fully-inflated 35c tire. Depends, I suppose, on rim width. Our bikes have relatively narrow rims (Bontrager on one and Mavic CXP 30 on the other), and I can just slip an inflated 28 c through.
