<p>The only real downsides of this offset holder is that they might be a little more difficult setting up to sit on the rim in the correct plane and the correct toe-in. They will want to rotate if you squeeze the brake lever rather than bedding in on the same plane and self-adjusting with the concave washer.

<p>The only real downsides of this offset holder is that they might be a little more difficult setting up to sit on the rim in the correct plane and the correct toe-in. They will want to rotate if you squeeze the brake lever rather than bedding in on the same plane and self-adjusting with the concave washer. You will have to hold them exactly where you want them as you tighten the pads without the help of the brakes keeping them from rotating. You'll need strong fingers to hold the pad against the rim while you tighten the bolt down to keep it from rotating or twisting on the eye-socket washer. Not impossible, but a little more fiddling around -especially if you have a rack or other things in the way impeding your access to the brakes and making it hard to get your hand in there.</p>
<p></p>
<p>Once it is set, you should never have to fiddle with it again. Just replace the inserts as they wear out. As long as you don't loosen up the bolt they shouldn't change their adjustment. </p>
<p></p>
<p>A set of <a href="http://www.amazon.com/gp/product/B007FWPD2Q/ref=wms_ohs_product?ie=UTF8&psc=1" target="_blank">Jagwire Brake Pad Tuner Toe-in Tools</a><span style="font-size: 13px;"> </span><span style="font-size: 13px;">would come in handy to help this procedure along.

<p>I would be less worried about post breakage than just plain old power/feel-robbing flex. </p>
<p></p>
<p>Canti brakes already often suffer from sponginess from the fact that the posts splay outwards as the chainstays/fork blades twist against the force of the brake arms pressing inwards on the rim. On caliper brakes the brake bridge only really has to hold the brakes against the spin of the tire. That's why Sheldon Brown's <a href="http://sheldonbrown.com/home-drop.html" target="_blank">home-made brake drop bolt hardware</a> made of reflector brackets actually worked. I've done similar with sidepull brakes and it works very well. </p>
<p></p>
<p>But with cantilevers and V-brakes (and U-brakes) the pivot posts also have to contend with spreading forces as well as the braking forces. The spreading/clamping force is actually much greater than the braking forces.There are some frames that have issues with spongy brakes because of the posts spreading as the stays/forks twist and that is why <a href="http://www.amazon.com/gp/product/B0099HRNI2/ref=wms_ohs_product?ie=UTF8&psc=1" target="_blank">brake booster arches</a> were invented for them. </p>
<p></p>
<p>With the type of canti-post drop hardware that the OP is thinking of using not only will there be the two places of force applied on them (braking/rotational force & spreading/twisting force) but a third new force will be introduced: a splaying force as the hardware will want to swing outwards to the sides like a pendulum of a clock. So the poor canti posts will need to withstand the rotational push/pull (depending if front or rear brake) of braking force, the twisting force of resisting the squeezing of the brakes against the rim, plus the new pendulum force that is trying to twist the posts as well -a force that on a regular canti post is only what is necessary to spring the brakes back open. That spring plate was never meant for that kind of force, only enough twist to push back the brakes when the springs open them back up when the brakes are let up on the lever. </p>
<p></p>
<p>I personally think this hardware is not going to work very well for the OP. While it might not "rip the posts off of the frame" it will certainly result in really spongy ineffective brakes. That's the whole problem in the first place with trying to do a 27" -> 700c conversion in the first place. A good mechanic can find a set of cantilever brakes that will still hit the rims, but tuning them for good feel and power is pretty hard. The brake booster arch I linked above helps a lot. I think it might even help with using the drop hardware.</p>
<p></p>
<p>In the end I'd suggest just buying a nice set of 27" wheels or having them built up around some strong CR18 rims. Pana Pasela makes an excellent tire for 27" rims. Or if you really want to go 700c then just don't use the canti studs and use a set of Dia Compe centerpull brakes. They work really well and can be bought at Working Bikes for $2 set. They have literally hundreds of them piled up in the brakes section to pick from. Rebuild them and they are just as good as the ones that <a href="http://store.velo-orange.com/index.php/dia-compe-610-centerpull-brake.html" target="_blank">VO sells today new for $85 each</a> (better if you ask me as drop-forged is stronger than CNC milled) Also, you might need the 750 model rather than the 610 for a little more reach and WB has both. Centerpull calipers are every bit as good as cantilever brakes if you use good pads like KoolStop and can swallow a 35mm tire and fender no problem.</p>
<p></p>
<p>I use them on my own bike and they stop just as well as the Ultegra dual-pivot calipers I had on there before with Sheldon-style drop bolts. </p>

<p>Honestly, if anybody knows a good engineer or knowledgeable mechanic, I'd like to talk to them. I'm having a little trouble understanding why dropping the posts 16mm with the post extenders would cause so much trouble, where, <strong>as I said, all the original brazing would stay intact and there would be 1cm of thread for the M6 bolt into with 3 millimeters thick diameter of metal all the way around the bolt down to the base of the post.</strong></p>
<p>My mechanic also went on to say that I would need a <a rel="nofollow" href="http://www.bikepro.com/products/brakes/brakeboost/oddy.html" target="_blank">brake stiffener</a> to make sure the post extenders wouldn't rip anything off, so.... </p>

<p><br/> My mechanic has a hissy fit and said that the Elevn Post extenders will rip my canti mounts off eventually and that putting an M6 through the middle of the base of the posts will not be adequate to prevent this from happening. The posts are designed for M6 bolts, and cutting off the top where the brake mounts in order to fit the Elevn Post extenders didn't seem like a huge deal, since all the brazing would have been intact. AND replacement studs could be put without any brazing or welding on if there was ever a problem. I mean, COME ON, there is 1cm of metal to thread into after the top of the post is cut!<a href="http://storage.ning.com/topology/rest/1.0/file/get/35255562?profile=original" target="_self"><img width="721" src="http://storage.ning.com/topology/rest/1.0/file/get/35255562?profile=RESIZE_1024x1024" width="721" class="align-full"/></a></p>
<p>Honestly, if anybody knows a good engineer or knowledgeable mechanic, I'd like to talk to them. I'm having a little trouble understanding why dropping the posts 16mm with the post extenders would cause so much trouble, where, <strong>as I said, all the original brazing would stay intact and there would be 1cm of thread for the M6 bolt into with 3 millimeters thick diameter of metal all the way around the bolt down to the base of the post.</strong></p>
<p>My mechanic also went on to say that I would need a <a href="http://www.bikepro.com/products/brakes/brakeboost/oddy.html" target="_blank">brake stiffener</a> to make sure the post extenders wouldn't rip anything off, so.... </p>
<p><strong>HELP!!!! I want to ride my bike! :-(</strong></p>
