Disc Trucker Brakes & Drivetrain

Surly Disc Trucker Shimano XT Drivetrain

Today the disc brakes, integrated crankset/bottom bracket, and rear derailleur were installed. The front derailleur and chain were also on the agenda to complete the drivetrain but unfortunately, I needed a shim to fit the front derailleur to the frame. I was sure I had one. But as you can see my workshop is a disaster and as a result I couldn’t find it. I really need to get more organized.

I chose a mountain bike drivetrain over road bike components because this bicycle will occasionally be called to duty for self-supported touring. In those cases, the 48/36/26 tooth chainrings will make the job a little easier than a traditional 52/39/30 and the 26-tooth granny gear will save my knees on a climb over the 50/34 tooth compact crankset.

I also chose mechanical disc brakes over hydraulic brakes because they are much easier to service in the field.

Tip: – Installation of the cranksets and bottom brackets require specialized tools. If you don’t have the proper tools take them to your local bike shop for installation. Don’t try to improvise with other tools, you will only destroy your parts.

Tip: – If the manufacturer hasn’t already treated the threads of your parts, I recommend using anti-seize compound. It will make the assembly and disassembly easier as well as lubricate and protect the parts from rust and corrosion. If you have to take your bicycle apart down the road some time, you will be glad you did.

If you are unfamiliar with the installation of a bottom bracket, Park Tool’s website does a wonderful job on installing one at https://www.parktool.com/blog/repair-help
