2008 Surly Big Dummy frame

I just bought this frame and wondered if there were any suggestions for the build. I plan on getting most of the parts from an old GT Avalanche of mine.

The previous owner suggests that I go with disc brakes, but I'm not sure it's in my budget. Will I be OK with regular brakes?

Any other suggestions will be appreciated. I'm really excited about this!

Disc brakes are nice but not necessary--a decent set of v-brakes will do just fine. You can always upgrade later if you want to.

How hilly is it where you are and what parts are you using from your GT? If you anticipate carrying a lot of heavy loads you may want to invest in a triple crankset (or just something with a granny gear)

Keep us posted (with pics) on the build!

Discs are nice, but well adjusted, good, v-brakes with nice pads (like the salmon kool-stops) are good too.
+1 to having low gearing. I don't need it much but when you need it, you need it.

I am not a big fan of v-brakes on cargo frames. I say this because the braking surface is the rim itself. Well on a cargo frame, the load of the bike is on the rear wheel. Slowly removing metal from the wheel, which is what handles the load, just does not make sense to me. To me the investment in a set of Avid BB5 or BB7's is cheaper in the long run than the cost and labor to get a new wheel, build it and true it.

That is me and I could be wrong. It wouldn't be the first time! I went ahead and upgraded the rear to BB7's on my xport. I love the feel of the cable discs though.

+2 to good gearing!

Rim brakes work just fine, actually anything other than stuff from department stores works fine when set up properly. I would just keep what you have as the avalanche should have fairly tough parts considering it is a mountain bike, now is a great time to clean and lube the parts as needed like greasing the hubs and truing wheels while they are off.

Mark, as an owner of an older Big Dummy, You made a good choice.

If you're going to use it for normal grocery shopping and hauling things that aren't pushing the weight limit of the bike, rim brakes will suffice. If you're flying down mountain passes with a heavy load, you should get the disc brakes. Using as many of the components off the old bike as possible will save you money, and yes, you can eventually upgrade to disc brakes.

If you upgrade wheels before brakes, be sure to get disc-compatible hubs.

My Dummy has BB7 brakes. It'll stop faster than what's comfortable for my body.

Rim brakes are fine. Although the long run to the rear wheel will require longer than typical cables & house. If you can spring for something that's a friction free and anti-compression as you can afford the performance of the rear brake will be improved.

Depending on your cargo and how you ride the rear wheel may not survive long. I would definitely get the rear wheel looked over by a professional wheel builder to ensure the tension is good.

Other than that have fun and enjoy your new [to you] Dummy...

Thanks everyone. I think I'll try the rim brakes for awhile anyway. Around town errands of groceries, etc. Not too much weight and no hills to speak of. I do have a triple on the front. Random answers to random questions.

I'm so excited I can hardly stand it.

I have hydraulic disc brakes on my Dummy. A 203mm up front and the 180mm in the rear stop the Dummy with ease. I had my Dummy with disc in mind when went about getting parts for it.

It's now in my builder's hands. I think he's as excited as I am. Hopefully done by Tuesday. I'll try & post pics when it's done.

Why not use both at once? Get a pair of those dual cable brake levers (intended for use by amputees), with a pair of v-brakes, and a pair of mechanical disk brakes.
give each wheel a disk brake and rim brake at the same time.

It turns out that I would need new wheels to accommodate disc brakes. At this time, not in the budget. My builder is also having some trouble with the brakes due to cable routing and cable stops. If any of you have any suggestions, let me know & I'll pass them along.
