BONNIE MOD UPDATE
Dime City Cycles Rear Set

When I installed the Dime City Cycles rear set, I used their supplied 90° banjo fittings (see BONNIE MOD #5). I found the brake line to flow very awkwardly. In fact, I had to run it outside the side cover (see picture below). Not only was the brake line crimping, it was 100% exposed to me hitting it with my boot or worse, getting shredded should I go down (though I’m sure that would have been the least of my worries).

So I ordered a few Galfer banjo fittings from Dime City – a 0°, a 12°, and a 40°. I wasn’t sure what would work best until I physically tried them. I was, however, expecting to swap out both the original 90°. After a few minutes experimenting, I found that running a 40° off the master cylinder and keeping the 90° on the junction worked superbly. The brake line now flows naturally without kinks and runs behind the frame, safe from harm. (The Galfer fitting I used is here.)

And there you have it. Much, much cleaner.

Note: Make sure that you toss the old crush washers and replace them with new ones. Any time you release their seal, they will no longer work properly.

  1. Hello there I have a question about the rear set adaptation break line
    1-how long is the line between banjo elbows?
    2-What’s the size on the switch couple between the line coming from the master cylinder line and the caliper line?
    Thanks
