My Big Dummy Build
Hi all,
Been seeing some talk here lately about the Big Dummy and thought I'd join in.
I just built up my Dig Dummy and thought I'd share some of the details. I know it's a bit long, but I'm a wordy person.
The frame is a 20 inch Big Dummy that I ordered as a frame and fork from my LBS.

A little background here. I'm about 5' 11" and this 20 inch frame rides nicely with drops and
100mm stem that has about a 10-15 degree rise (I don't remember the exact rise sorry). Granted
I do have more torso than legs and was going to order an 18 inch frame, but this one fits nicely.
My overall impression is that this frame is very well built. Nice clean welds and a very good job on the powdercoat.
The only thing I had to do to prep the frame was chase the threads on the bottom bracket.
Other than that this frame was good to go.
For the build I used components that I've been hoarding since I first read about the Big Dummy
at interbike 2006. Yeah, I'm one of the dorks that's been waiting 2 years for this frame.
The only component I didn't have were the wheels. Everything else was in a parts bin or off
another bike.
Also, I haven't ordered my xtracycle components yet. I wanted a bike in hand before I ordered
the rest.
Here's a list of my components:
Salsa Bell Lap Moto Ace bar
Tektro Road Brake Levers
Dura Ace Bar End Shifters
Paul Touring Canti Brakes front and rear
Campagnolo Veloce Triple Crank (52/42/30)
Miche 112mm Bottom Bracket
Shimano Ultegra Frond Derailleur
Shimano XT Rear Derailleur
Shimano XT Cassette 11-34 9 Speed
Brooks Team Pro Saddle
Thomson Elite 27.2 330 silver seatpost
Maxxis Overdrive wheels 26x1.75
The wheels are some Araya wheels that I had laying around. My real wheels aren't done yet.
However when they are, they'll be Shimano XT hubs laced to Salsa Gordo rims. Front will be a
disc compatible dyno hub, while the rear will be disc compatible. All black.
The bike went together easy enough. There were only a few challenges that were easily solved
just by looking at the problem and applying a little common sense (and some outside the box thinking
from time to time).
The brakes work well with this bike. Also, Paul Canti's have to be the easiest Canti Brakes
I've ever set up.

Initially, I thought the rear Canti would be more difficult to set up. It was a looong way from the
seatpost to the straddle wire on that Canti. Luckily, I was able to attach a rear cable hanger
and route the cable well enough. Works much better that I expected it to.

Drivetrain went in easily too. The big problem I was expecting was my front derailleur. The
Big Dummy is designed to use a Mountain Bike style Top-Pull derailleur. Well, since I was
using Campy cranks, that was out of the question. There are no Top Pull FD's that will
cover a 52 tooth ring. I thought about removing the big ring and putting a bash guard there and
just buying a FD that would work with my 42 tooth ring, really how often would I use a 52 crank
on a Utlilty bike anyways (I know you're all thinking that)? However, you really don't see
many bash guards on the market with a BCD of 135. So I thought it out.
Problem Solvers makes cable stops that would generally work great in this situation. I had actually
sort of anticipated this and ordered one a while back. My goal was to place it on the downtube
about where bar shifters would go and just route it like any other cable. Unfortunately, the downtube
on the Big Dummy is huge. Almost 35mm IIRC. So that didn't work. I ended up using a few zip ties
and putting the cable stop on the seat tube. It works pretty well and was much cheaper that
having to buy a new derailleur.

The chain is a little longer than 1.5x a regular chain. I also put some tape on the cross member
to prevent any chain slap. However that hasn't been a problem yet. As you can see I have plenty of
chain clearance. This pic is about middle on both ends of the drive train.


This bike rides very smoothly. Handles well, but does take a little getting used to. I think
one good 15-20 miles ride should make you about as comfortable with it as you can get. However,
I would also recommend putting a little tape of some sort on the rear of the frame on the part
that looks like footsies. Until you get used to the extra length of this bike, you're gonna
turn a few corners too sharply. Trust me, I know this because I've already scuffed the powdercoat
in that very spot. In the picture below it's the semi circle in the bottom right hand side of the
picture.



Man I love this bike. Reminds me why I went car free two years ago. Hopefully it will
help ease some of the hard parts about being car free as well.
Hope this has been helpful for those of you that are either building up your frames, or waiting
on them to arrive soon.

I like it quite a bit. The bar tape is a little intimidating, the whole bike has a whole rough utilitarian vibe to it, and then.. BAM! Its like the 80s in here

Glad you are enjoying your BD. Post some more pics with the Xtracycle longtail kit when you get it....

The Pauls just screw onto the frame post with a single screw. The unusual thing about them (compared to Canti's I've used in the past) is that you can adjust the spring tension and set of the brakes with a wrench instead of lining them up on one of the 3 frame holes that most canti's need for the spring tension. Took less than a minute to get them just how I wanted them.
IMO it's hard to go wrong with Paul Brakes. Quality is fantastic.

Actually, looking at the Surly blog they mention something about the paintshop. I guess I really don't know.

Chris, your Dummy is a great example of what I like most about Surly builds (well, not so much their complete bikes). No two are quite the same. Where else will you find one bike with Veloce, XT, Dura Ace, Ultegra, Paul, etc.

Technically, you can remove them (they weigh a lot) and were put in place for shipping. It doesn't hurt to leave it in place but I personally wouldn't.

@Chris: I don't know that I'd ever set up a Dummy with Dropbars, cantis, triple road crank, or without full fenders and a dynamo light; but I like yours and I like that someone out there wanted all of that... Sweet Bike!

Nice Big Dummy Chris.
I built mine up with a SRAM X9 rear derailleur because of the stronger return spring. With this spring there is no need for a frame cover to protect from the chain slap.
I used Schwalbe Big Apple tires 2.35 for the best load rating (160kg) I could find. Also the built in tire suspension works amazingly well.
For stopping power, I used Avid BB7 disc brakes front and rear. When it’s wet and loaded I want to stop like now, if needed!
I love my Big Dummy. But my build cost me around $2,300, so I’m not too comfortable leaving it locked up outside the grocery store.

Its too big a bike to be practical for a bike thief and its very conspicuousness makes it hard to steal. You want something that can be tossed casually onto a car or pickup truck to be resold later. And not many can afford a BD. If I was a thief, there would be far easier and more profitable pickings. Besides a Surly just looks fugly!
