Mini-V brakes will they work with Brifters?

I'm currently running the OEM V brakes that came on my '07 Sirrus with Travel agents to use with Sora Brifters in drop bar configuration The problem is the travel agents tend to be a PITA to release to remove wheels. Not as bad as tensioning the cable to work without them, but still I'd like a work around. Do Mini-Vs have the right ratio to work with brifters??

This website that sells short v-brakes says they're long pull brakes, like normal V or linear pull brakes.

I'm using the cheap Tektro mini-Vs with Campy levers and they're working fine. They do need to be pretty close to the rim but nothing crazy.

They were purposed to do that ..Shimano new road brifter pull ratio changed , TRP, made the arm a little longer.

TRP, 8.4 shown their 9 is just that 6mm longer.

Yes. That's the whole point.

I'm running Tektro 926A mini-Vs with Shimano 5700 105 brifters. Yes they work great.

There are 90mm mini-V brakes, and 84mm ones. It's best to have the correct one for your brake lever's pull.

Longer brake arms need more cable pull, so the 90mm with the wrong levers might bottom out before the brakes are fully engaged.

I know that the 84 works with Campagnolo brake levers. I had to set the pads very close to the rim, closer than I do with regular road brakes.

I think the "newer" Shimano levers work best with 90mm, but I never really checked on it.

Me too, otherwise one and two finger braking will tend to chop the shift lever into my other fingers.

If you're having trouble getting Travel Agents to release for removing wheels I don't like your odds for getting Mini-Vs to work any easier while removing wheels. I've always had to resort to some kind of work around like clipping the nose of the noodle to make it release a little more easily or using a noodle with a barrel adjuster to ease the tension before removing a wheel. For that reason I don't like Mini-Vs.

I'd be interested in knowing what the folks who have posted positive reviews do to release wheels. Am I missing something obvious?

When I used mini-Vs with Campy Ergo I installed noodles with barrel adjusters, since of course there is no barrel adjuster at the lever. The Campy Ergo brifters do have the little quick release button on the lever that releases a bit of cable. Popping this button is enough for me to open the mini-V brakes.

I purposely set them up "loose" and then tighten them up using the cable adjuster on the noodle (Jagwire replacement one). Then I can just unscrew the adjuster and unhook the brakes easy. This is with 700x40 tires and Tektro 926s.

Shimano STI work well with mini-V up to about 90mm. They brake well and feel like normal road callipers. I run Microshift brifters with 90mm arms and 2.1 mountain bike tires - which I wouldn't recommend because they give inadequate clearance - but other than that it works well. You don't need a button on the levers for clearance because you can just pull the noodle out of the brake to open the callipers enough to remove even a 2.1 inch inflated tire. I believe the 85mm arm mini-V are made for SRAM brifters. The 80mm mini-V made for BMX bikes work well with brifters and skinny tire road bikes. The general rule with V-brakes is to use the shortest arms you can get away with. I went too far with it and will end up replacing my rear mini with a full sized 103~107mm V-brake and Travel Agent for more clearance.

MY Sora Brifers are ST-3303 and I believe my current TEkro V brakes are 90mm arm length. I have Mini V's on hand that are 80mm arms. So the upshot is these Mini-V (TEKROS 926AL) will do what I'm looking for correct?

I think those 926AL will work best with your brifters, but it also depends on how big of a tire you intend to run. For roadie tires those 80mm arms are best but if you intend to run big fatties maybe you want longer arms. I don't quite understand why you can't pull the Travel Agents from the noodle retention bracket on your existing V-brakes for more clearance when you remove the wheel. Are the brake pads too close to the rim and the cable not slack enough to achieve the 2 or 3 mm pull needed to detach the Travel Agents from the bracket? With shorter armed v-brakes you'll have more brake pad clearance and the Travel Agents won't be necessary. If you live in the mountains and require extra braking power then longer arms provide additional leverage but at the expense of less pad clearance to the rim, and less cable slack. That sounds counter-intuitive. You can also swap the spacers on the brake shoe posts to create more rim clearance, exchanging the fat spacer for the thinner one, or add a washer or two to reduce clearance.

Here's a photo of the 80mm (I think) v-brakes with a 37mm fat tires. Still plenty of clearance:

Those will work for sure, and at $12 each, they're not much of an investment if they don't work!

Where did you get your Tektro brakes? I'm having a heck of a time finding the right model (the one with two brake boss bushings, one inside the other).
