More upgrades on the R90

I did the final upgrade on the R90 before the summer road trip today. I got the brakes upgraded from a single sided disc to a dual disc. Basically, I gained 30% more stopping power and dropped about 60% of the hand pressure required for stopping. While we had the front end apart, we went ahead and put a set of anti-dive springs in the forks. These help control the way the forks compress during heavy braking. While we had everything torn apart, we also put in stainless steel braided brake lines and new fork seals.

I can tell a big difference with the new setup. Before, I had a whole lot of "go fast" but very little stop. Now, I can reel in the speed much more comfortably. I don't feel like I am breaking walnuts just squeezing the brake lever. Since there is a disc on each side of the wheel now, I don't get any lateral torque when I grab a handful of brake. It is very even and tends to run straight, instead of drifting left. The brakes also feel like they recover faster than they did before. The new suspension setup in front is also very nice. I can grab some front brake to start my weight transfer going into a corner, and it feels much smoother.

Now it is time to finish off the suspension update on Kel's bike. We got her heavy duty progressive shocks on the back, and the new progressive fork springs for her forks have come in. Now it is just a matter of installing them.

Unfortunately, I didn't get any shots of the brake swap. I am planning on taking the large format on the road trip this summer. My plan right now is to go to Canada. I just have to find myself a tripod heavy enough to support it, and small enough to fit the bike. I do have most of my other shots posted over at though.
