How To: BB30 Overhaul/Bearing Replacement

ShareThis

By now, you're likely familiar with the fact that your Volagi Liscio is equipped with what's called a BB30 crankset. Essentially, BB30 equates to a crank that features a 30mm spindle which is made from aluminum rather than steel, that resides in a bottom bracket that is 68mm wide. The bottom bracket utilizes bearings that are much larger than a traditional bottom bracket, which should theoretically cause them to be more durable. The BB30 standard is more than just a new standard however, as it offers increased crank stiffness, better pedaling efficiency, lighter weight, and reduced Q-factor/U-factor (foot stance/ankle clearance).  The main disadvantage comes when it's time to service your BB30 as it requires new tools and techniques compared to BSA (threaded) BB's or even BB85/90. Unfortunately, this means that BB30 maintenance will be out of reach of most home mechanics.

However, if you're the do-it-yourself champion, this guide should help you perfect the technique, and with a few additional tools you should have your BB30 up and running in no time. Many of the tools pictured are professional level tools which we know are way too expensive for the few times you will need them, but most tools have a consumer model available that should do the job just fine. As always, if you are doubtful of your ability to perform any of the following steps, save yourself the hassle and take it to your local shop. Ready? Dive in after the break!

The Volagi Disc Brake Chronicles: 4 Short Videos About Your Brakes

ShareThis

Disc brakes have been around for quite some time now on mountain bikes, tourers, tandems, even hybrids, though for road bikes we're just starting to see the coming wave. While there are a lot of folks who have plenty of experience with discs from working with other types of bikes, there are still those who are essentially forced to learn an entirely new braking system now that discs are being found on wheels boasting skinny tires. As it turns out, there are a lotof questions out there from people across the board about set up, adjustment, and trouble shooting that we hope to at least partially address with this video series. Obviously, these videos are tailored to the Avid BB7 mechanical, though most information should pertain to most mechanical disc brakes, and a little of it like keeping the pads and rotors clean will pertain to hydraulic brakes as well. It should come as no surprise, but hydraulic discs will eliminate many of the steps needed to make mechanical discs work and feel good, but we'll get into that later.

Keep in mind, this is no replacement for proper disc brake set up and adjustment - without that, these videos are pretty much useless. If you're facing any of the issues described in the videos and haven't checked out our initial setup and adjustment videos, we highly suggest you do so, before proceeding with any of these. One of the things we didn't cover in a video is checking the trueness of the rotor itself. Honestly, it's very unlikely that you will run into a rotor that is warped enough to need to address it, and if you do it's best to leave that to someone who's done it a few times to avoid ruining the rotor. If you take the time to properly set up your disc brakes, they will reward you with great long term performance and reliability.

In order to properly see the videos, simply watch it full screen. I apologize for the size of the video, as it wasn't until after filming and editing for hours that I realized youTube really does not like portrait videos. Lesson learned, thanks for the understanding. Also please realize that it is nearly impossible to fit every bit of knowledge of disc brakes into a series of videos, no matter how long. If you've gone through the videos and are still having issues feel free to ask a question, or take it to your local bike shop.

With that, check out parts 2-4 after the break to dial in your brakes!

Videos: Mechanical Disc Brake Set Up For Your Volagi

ShareThis

Obviously, the Avid BB7 disc brake is a huge part of what makes the Volagi Liscio special. There are a lot of folks out there who have certainly earned their stripes when it comes to setting up disc brakes, but there are also those who may not be as familiar with them.

Then there is the brake itself. The Avid BB7 is a great brake, but it does have its eccentricities that can frustrate even the most seasoned mechanic during set up. While we already had one video published on disc brake adjustment, in the spirit of continual improvement we've created two new videos, one for the initial set up and one for the actual adjustment, in order to help anyone through the process of getting their brakes dialed in.

Jump past the break to see the adjustment video, along with a word on proper housing length!
