From another post, I just installed a new carbon fork and R600 brake on our '05 Trek T2000. Front braking is greatly improved. I've always had great bikes on my MTB's and road bikes, but tandem has always been a little iffy. Now that the front is good to go what if anything should I go in the rear?
I'm currently running the original stock Avid Shorty 6 with an aftermarket Drum brake. The drum brake does it's job and works great, but the Avid is very soft. So I've been thinking of some options:
Do nothing - We've ridden the bike as is for several years, and really haven't had any problems.
See if the bridge could be modified to support the rear R600 road brake - I like this idea if the existing bridge was strong enough to support a caliper. Currently it contains a boss for a fender, but the hole does not pass thru. I don't really want to have it cut out and moved or replaced as paint would be difficult to match and cost. I've not looked closely at the spacing, so need to investigate a little more.
Switch to a v-brake and lever adapter - Although space is tight with the rack we use, might be the simplest solution, and I already have the parts.
Swap out the drum and canit's for a disk - I like this solution, as we could save a bit of weight, it's clean, but I've read here the disk won't give us the same performance as the drum. Although, here in Indiana the drum is nice, but only rarely needed. I might have some rack issues, and it's a more costly solution.
Sorry to ramble on, sort of thinking out loud.
