strange Dia-Compe aero brake levers
I picked up a pair of Dia-compe aero brake levers at a garage sale
today. Now that I have them home, I am wondering what it is I really bought. The hoods and clamp look normal- black rubber, embossed R or L on one side, Dia-compe on the other. The levers look fine until you get to the pivot area.. There is a black plastic semi-circle that wraps around the top a bit, held in place by a small allen bolt. This bolt bottoms out before the plastic piece is held still, so I wonder if there is a piece missing. The top of the bolt has an unthreaded section, and it looks like a washer (quick release lever??) would fit into a recess in the plastic piece. This bolt also captures a large aluminum block that has a recess at the top edge for the cable mushroom and a slot of the cable to go through a hole in the base of the body. This block pivots (when the bolt isn't holding it in place) around a point about 3/4 inch beyond the lever pivot point. At the pivot point there i a small set screw holding the axle (?) in place. The allen bolt for the clamp is tucked underneath the pivot point, and it looks as if I will need to remove the lever in order to clamp the body to the handlebars. Any ideas? I have searched for photos/descriptions, etc. of Dia-Compe levers but see nothing that looks similar. Are these usable as standard aero brake levers on a road bike, or are they specifically designed for another use? Thanks for any help. |

Sounds like you have 287 V brake levers which pull more cable. Good for V
brakes and some canti's. Seems to me that when used with road calipers you lose modulation. Gary Jacobson Rosendale, NY "Dan Daniel" wrote in message ...

Gary Jacobson Rosendale, NY OK, found them. The first couple of places I went for the 287-v had the wrong picture. Any idea if they will work with dual pivot brakes? How about side pull brakes? I have an old pair of 105 standard reach brakes that will fit on the bike. |

I looked at photos on the web too, even though I have two pairs, and it
could be that there is a newer cleaner looking version. Or maybe the photos I saw where the older cleaner looking version. I think that these extra cable pull levers were once called 287 and the "V" came later when V brakes became popular. There's a spring in the lever which seems to easily break. Just broke one yesterday, and a used set I bought had a broken spring. Not a big deal if tension in the caliper spring is good. But I wish I could find replacement springs anyway.

If the levers won't do much with dual or single pivot side pulls, I might have a pair for sale very cheap With working springs in each! |

If these are the "V" levers (that is not entirely clear, there is a similar non-V lever that will work fine on most sidepulls), then don't sell them too cheaply. They are fairly expensive (around $40-$50 if memory serves) and much in demand. -- David L.
