Ultegra BR-6700 Brake Compatibility Question

Has anyone tried these with other than Shimano 6700 brifters and with what results? Shimano's documentation states that the brakes are too sensitive with other than the servo wave brifters.

Wondering how they would work with normal drop bar brake levers or even V brake compatible drop bar levers. I would presume that the V brake levers would reduce the sensitivity due to the lower lever ratio and greater cable pull for a given lever movement.

Originally asked this in the road forum and only one response that made sense but it did not answer my question.

Bolt 'em on and try 'em.

Then you can tell us.

I did order a set as Colorado Cyclist has them at a better price than I could find most places for the older NOS BR-6600 calipers. Should be here by Friday hopefully along with a set of 287V Dia Compe levers for just in case Shimano is telling the truth about the brakes with normak road levers. I needed the levers anyway for another project.

I am just surprised that no one has tried out the "not recommended" combination. What has happened to curiosity and bike hacking? After all people post regarding using Shimano wheels and cassettes, and even derailleurs, with Campy brifters.

I guarantee a number of people have tried those brakes with normal levers, it's just that nobody's written about it.

If I had the inclination to buy a pair of short reach brakes for $140, I'd happily try them with normal levers and write about it, but I don't really need them. We haven't gotten in any yet here either, we're not exactly burning through short reach brakes at Harris Cyclery. Curiosity isn't dead, I assure you, it's just elsewhere.

I tried the opposite combination - 6700 lever with standard brakes. I certainly noticed a difference, especially because I have that setup for the rear brake and a standard brake lever and standard brake for the front on the same bike. I wrote about my impressions and the information that I was able to find in this thread: Shimano 6700 & 7900 brake lever pull ratio: Opinions & info. I also didn't get much of a response to my questions, but my measurements suggested that the new levers pull the appropriate cable to operate V-brake levers, and that is also what TandemGeek wrote in this blog posting, see point b/c in this post. I asked him to confirm this info for me, but he hasn't responded.

I'm also surprised how hard it is to get an informed answer on this.

BTW, it's a shame that you ordered the Dia Compe 287V levers - they are a very old design, the hoods are not nearly as comfortable as the Tektro/Cane Creek V-brake drop-bar lever.

I've got a cable pull measuring jig in the works. I was thinking more along the lines of using it for shifters, but I'll get definitive measurements of pull for the new brake levers as soon as someone around here gets around to ordering a set.

I ordered the Dia Compe levers based on a post in the Yahoo Geared Hub Bikes group that the Tektro/Cane Creek levers wear out if used a lot. Per the post the plastic used in the bodies is a bit soft and the cable quick release can wear away the area it contacts. The poster indicated that h had worn out two pairs IIRC.

I have the Tektro "standard pull" (caliper and cantilever) aero brake levers on one bike and, after a couple of thousand miles, they seem to be holding up fine. Obviously from my nom de forum, they get used a lot. So far, so good and at $20/pair, even if they wear out a bit fast, the cost of replacing them is quite minor.

Also, they are super comfortable and do indeed mimic the shape of the 10-speed Campy levers I have on another bike and the cable quick release in these levers is a real plus.
