This will build up heat, but not too much. Roll forward and simply reef on the brakes hard for about 10 seconds. This is because the pads need to be bedded to the rotors. Bed your brakes: The first thing you might notice if you are new to disc brakes is exactly how well they don’t work when you first ride them.

Wheels Manufacturing makes spacer washer kits and Syntace makes very handy universal ISO spacers that will get your rotor position right on.Ĥ. Then space out the rotors on the other hubs to match. Check the position of each rotor in relation to the caliper and use the most outboard for the caliper setting. If you have all the same hubs, chances are everything will line up, but if not, you might need to space out your rotor position. It is important to make sure the rotors across each of your wheels are in the same position so you don’t have to re-align the caliper each time you change wheels.
Rotor position: In ’cross, even more so than mountain biking, you might be changing and using different wheels regularly. Changing rotors to another wheel will require you to repeat the process.ģ. Keep in mind that once you have a rotor perfect, it will only be matched to that particular hub. When truing rotors, take it steady until you get the hang of it it’s really easy to over-correct and make the rotor worse than when you started. Here’s where Park Tool’s DT-2 Rotor Truing Fork is a worthy addition to your toolbox. But depending on your rotors and the interface to the hub, there will usually be a little bit of waviness when the wheel is spun. True your rotors: Your rotors might arrive perfectly straight out of the box, if you’re lucky. I think there is more modulation control and smoother braking if the brakes start working about halfway through the travel of the brake lever.Ģ. I personally don’t like the brake coming on early in the lever travel. Once the caliper is mounted, it is easy to adjust brake feel at the lever by tweaking the pad position on the caliper. A handy tool to have at this point is a Torx T25 wrench the inboard pad adjustment on the BB7 can be rotated by hand, but it’s way easier with the right tool. The objective of the game here is to have your calipers nicely aligned on the rotor so it can be dialed in with no rubbing.

Now, I’m not going to get into all the gory details of mounting the caliper - there are a couple of cheesy but highly instructive BB7 install videos on YouTube that will set you on your way. The BB7 is incredibly easy to work with and the Caliper Positioning System (CPS) makes it possible to precisely align the caliper even if the mounting posts aren’t quite perfect. Get it right: Proper installation and setup are more critical for disc brakes than for cantilevers, because the tolerances are a lot lower and the calipers must be aligned and adjusted just right. For now, the BB7 is a solid performer and with a bit of tweaking and upgrading can be flat-out fantastic.ġ. Now, this all could change with a new product announcement from any one of the big component companies at Interbike next week, but it’s not clear that’s going to happen. 4 and Masters racers, if they’re going disc in 2012, they’re almost across the board on the BB7. After canvassing everyone from Tim Johnson () and Boulder Cycle Sport’s Brandon Dwight to the local Cat. The BB7’s simplicity, reliability and ease of setup set it apart from lighter cable-actuated calipers and even some of the hydraulic options currently available. It’s become pretty apparent that Avid’s 13-year-old design, the BB7 road caliper, will be the brake of choice this year in the new disc-heavy cyclocross market. We’ve been proponents of disc technology for ’cross for years and over the coming weeks, contributor Michael Robson will explore the burgeoning arena of ‘cross-specific disc brakes, from the new gear to tips on getting your disc set-up dialed. Nearly every manufacturer is offering at least one disc-ready frame and many of the sport’s heavyweights are adopting the technology for 2012-13.
