    Moving 105 rear brake to front - Front brake bolt question.

    I recently got a couple spare 105 brakes on the cheap at my local bikeswap, and I'm hoping to use them as a front brake on a SS/FG training project (to use in tandem with my road bikes).

    The brakes I bought were rear, and had the shorter bolt for going through the brake bridge, but won't extend all the way for mounting through my fork.

    I found this inexpensive front brake bolt assembly, but don't know if it will fit my 105 brake. For the price, I may just buy it and give it a shot...but does anyone know of an easy way or inexpensive replacement bolt to help me move a 105 rear brake to the front?

    Many thanks.

    We need to know more about your set up. What size is your fork steerer(1" 0r 1-1/8"), is it drilled for recessed nut? The center bolt you referenced most likely will not work with your 105 caliper. Sheldon had a few ways of useing a rear brake on the front.

    No, that bolt won't work. You might be able to use a longer brake nut, the kind used on carbon forks, like this: http://www.bikeman.com/BO1500.html?u...ign=GoogleBase they come in different lengths and may solve your problem. Something like this is commonly available at an LBS

    You're right, sorry - It's not drilled for a recessed bolt, and it's a 1" steerer (I believe).

    It's a vintage track bike, but it was drilled for both front and rear brakes when I bought it used.

    This bike has two rear brakes. I drilled the fork and used a 30 mm recessed nut that I trimmed down so it just clears the inside front of the fork crown.

    If you drill the current 6 mm hole in the REAR (ONLY the rear) of the fork crown out to 5/16" or 8 mm you can use a recessed nut to fasten the brake caliper. As noted, you may have to find a longer than normal nut to reach but it works fine when you do it.
