Hey Guys I just got a pair of paul's neo retro cantis for my cross bike, I ve got them installed but the fine tuning is becoming a beyotch!! any advice?

The directions included with the brakes are simple and very clear. You slide the metal flanged collar onto the canti boss post and tighten the screw with a hex key. The spring has to be properly tensioned so that the cantilevers lift away from your rim when the brakes are not applied. This is done with the hex key in the mounting hole screw and the shiny alloy spring tensioner block under tension with a 15mm spanner. You will tighten the hex key while you hold the spring tensioning block steady with the spanner. The directions say that the long axis of the spring plate should be vertical, but I have found that on the Neo Retro the proper tension is with the alloy block tilted away from the vertical by about 30 degrees. This gives the right amount of spring tension and brake pad liftoff but not too much.

You will have to decide how steep a cable triangle you will want to make with the straddle cable between the cantilevers. I have had success with an equilateral setup. Place the straddle cable plate on your straddle cable midpoint. Anchor the straddle wire to the keeper hook on your right cantilever and fasten the wire to the screw on the left cantilever. Leave about 15 cm of wire out beyond the screw. Attach the lever cable to the straddle wire hanger. I think these require 11mm wrenches; I used a crescent wrench on the back and a socket driver on the front. At this point, it is useful to have a helper push your cantilevers to the rim while you fix the bolt, or you can use a third-hand device as I did.

You might have to tune it a little bit, but this is the short and sweet.

I've been installing Paul Touring Cantis lately and they come with the same direction and have to be adjusted the same way. I've just taken to thinking about the vertical comment as a "start here and change as necessary" sort of thing.
