    What's the word on Mini-V brakes?

    I'm probably gonna use my Specialized Crux Elite as a road bike in the spring, put on slicks and do some races. I have some 105 and Ultegra bits I'm gonna be upgrading to anyway once cross season ends, so I was looking for ways to increase my stopping power for road riding. I was thinking of getting TRP CX 9 mini v-brakes. They look nice, but I was wondering how they actually are, if anyone's used them or something similar for cyclocross. My only real concern is mud clearance, because of the crazy mud we've had recently on the east coast. Are there any other issues I should worry about?

    I have no experience with the CX-9, but I swapped out my front canti for a Tektro RX-5 Mini-V. They are discussed in the Canti FAQ thread here http://www.bikeforums.net/showthread...lver-Brake-FAQ. The CX-9 is pretty, but its also pretty expensive for what it is. Here is a comparison with another option, the Tektro 926 (which go for under $15): http://bikehabit.blogspot.com/2010/1...-v-brakes.html The RX-5 (I got mine for less than $20) or the 926 may be worth trying out to see if you like Mini-Vs before dropping $100+ on the CX-9s.

    I loved the 926s back before 'cross season; they stopped well (of course with Kool Stop pads) and setup nicely. But once I got to the point where I needed to do quick wheel changes, they turned into a big PIA. Changed out for Avid Shorty 4s and haven't looked back.

    If you have STI levers/shifters, and they're not the newer models with more cable pull, stick with 85mm (brake) arms. Otherwise, your levers won't pull enough cable, and you'll need to run the pads extremely close to the rims.

    The lower-end BMX/MTB v-brakes will give you plenty of stopped power. No fancy Ti hardware, but if you replace the stock pads with something better, they're just fine. I've experimented with various v-brakes and pads, and posted about it here (brakes), and here (pads).

    Nice read. Thanks for sharing it. Did you still use your STI shifters?

    No, I run Tektro RL520 levers. I need 102mm v-brakes for fender clearance, and STI won't pull enough cable unless you use a Travel Agent.

    Before you make your decision, checkout issue 14 (the latest) of Cyclocross Magazine. There's a good writeup about the stopping power of Canti's vs V-brakes. Basically, the article shows that in most cases, v-brakes are stronger, but some canti's in the right configuration have about the same stopping power. Before shelling out the cash, you might want to play with your current setup. If you're going to be at Westwood Sunday, I'll have the rag there.

    just realize the more leverage , the smaller the rim to pad gap, for your setup.

    I'm probably gonna put some mini-v-s on my Full Tilt Boogie and race it in a couple of crits this year. Its light. Its stiff. Its got no bottle cages. May as well get some use out of it before next fall/winter!

    Here's a link to my (growing) list of v-brake arm lengths:

    I am riding the Promax P1 Short brakes. They were cheap at ~23 each and come in COLORS! I ride mostly buff singletrack and the pavement to get to said buff singletrack. They are a wonderful improvement from the cheap Avid cantis that came stock on my Trek Ion. Went from three finger death grip braking on descents with the cantis to one finger freathering with the mini v's. Lots of power. After about 4 months with them I am at a crossroads. The power is great, but they sure are a PITA. They lose their centering after any wheel change; too little clearance in the front fork to remove/install my front wheel with a 38mm tire; etc. I bought some adjustable noodles and filed them down to make wheel changes/flat fixes easier and they have helped slightly.

    TL; DR great power if you don't mind getting creative with setup. Im sure the TRPs are much easier to work with than my cheap Promaxes. Should'a saved my pennies... I might move back to my Avid cantis with some Kool-Stop Salmons for CX season.

    I'm definitely a convert. I used CX8.4s with SRAM levers and *loved* the amount of stopping power you could get with only a single finger. After upgrading to Ultegra DI2 I initially kept using the CX8.4s but ended up purchasing a CX9.0 for the front to get that extra bite. My suggestion would be to get the CX9.0s. If you go with a cheaper option make sure you get noodles with barrel adjusters.

    Mini V brakes are the best investment I have made in my cross bike. I tend to mountain bike on it more than I should and fork chatter drives me crazy, this is where the Mini-V's are nice, super powerful and zero chatter no matter how hard I brake.

    I have not run the TRP brakes but I have many miles on my Paul Mini Motos and can not say enough good things about them. They are pricey but man do they work well! MiniMoto from Paul Component Engineering
