Long reach brakes and cross tires

[vqdriver]

Anyone tried running cyclocross tires under some a long reach brakes? Clearances issues?

Shimano long reach, with pads at bottom of the slot with Michelin Jets,
cleared fine for dirt, never tried them on mud.

Besides the Shimano calipers Rivendell and Velo Orange sell some (made by Tektro?) that open even wider. Campy brifters have a brake release button that can provide extra wide opening when used in conjunction with the release levers on these other calipers.

If you use bar end shifters there are several brake levers with releases built in by Tektro and others.

For what it's worth, likely not much, here's the clearance on a bike I'm almost finished - was a 27" wheel, now 700Cx25. Long reach eBay dual pivots http://img.tapatalk.com/d/13/12/31/a6uva7un.jpg

I ran some Tektro long reach calipers on an old steel 27" frame with similar clearance as in the above image. It worked fine except when I rode through some really thick mud. It literally stopped me in my tracks--it just jammed up in the calipers and frame. It was a mess. But for normal riding, it was fine.

I have a Trek 400 with DiaCompe 101s and 35Cs, a Bob Jackson with Sachs single pivots and 35Cs, and a Nishiki with 1st gen. DA single pivots and 38Cs. I think all the frames were originally 27", and the calipers are all in the 47-57 mm reach range. All the tires are knobbies; IRC, Splzd., WTB respectively. No clearance issues but I don't play in the mud, generally speaking.

I can put Ritchey CX 35s on my bike with Shimano BR 650 brakes. It's my SoCal CX racer. One DNF last year in sticky mud mixed with wood chips.

I've used up to 700x35 knobbies with Shimano and Tektro long reach brakes with no problem on grass, dirt roads, and Acadia gravel carriage roads.

Caveat is with muddy conditions, don't think it would work very well.

[Ken Robb]

"working ok" can be at least two different things here. Really "OK" would be the ability to remove wheels without deflating the tires to gain sufficient clearance.

Working pretty OK would be having to deflate the tires to install/remove the wheels but having enough clearance to ride the bike:) after re-inflating the tires.

I have no issues with 35's and fenders

I ran 700x30 cross tires (I forget which ones) on a Gunnar Sport with 47-57mm brakes without fenders.

You'll need to partially deflate the tire to remove/reinstall it unless you're running Campy or a set of inline cable adjusters plus allowing for cable slack to be dialed in at the caliper too.
