I did not build mine as I bought it complete through the LBS while QBP had them on sale last spring. I have made the following additions/changes though.
Installed VO stainless steel fenders.
Installed a Surly front rack
Installed the Xtracycle kickback center stand
Installed a Axa Defender ring lock under the snapdeck for locking the rear wheel. Basically a hidden security addition.
I am currently in the process of gathering the parts to build a Dynamo hub front wheel so I can add dynamo lighting to the bike. I am using an Alfine dynamo hub and a Salsa Gordo 36 spoke rim.

Can't thank you enough for this thread! I'm getting a Big Dummy as soon as the new frames are available (December?), and I've been reading and re-reading this thread daily to sooth the pain from the many long days I have to wait for my BD. So much great info and insight - and the sketch/breakdown of The Goat you did in your sketchbook is fan-freaking-tastic!

VanTiki: I'll trade you my Big Dummy for your location. I used to live in Oaha and miss it very much...Having a Dummy on the North Shore or anywhere downtown would be the bomb! Although...being a *****, I'd probably get a bucket of poi thrown at me: "Get outta da road, bra!" **

I've lost count of how many times I've read through this thread. It really has proven to be a valuable source of info. My girlfriend and I are finally gathering parts to build ours up!
Our main decision right now is if we're springing for Rohloffs or not. Once we decide that we can pick some rims which really have us confused. Building form the frame up for the first time is fun but a bit more overwhelming than anticipated.

Share the road.
Go for the Rohloff's and you won't ever think how good it would be with them. That doesn't read like what I wanted it to say. I am for getting the serious IGH for my dummy.

I too have embraced the BD contagion, with a frame hanging on the basement wall and parts slowly trickling in, plotting my build (blatant plagiarism). I was wondering if you see any benefit to something like the Terracycle idler, w/ the Rohloff?

How do you maintain chain tension?
Thanks,

On a separate note, using something like this, you can convert the dummy to a belt drive, no need to split the frame.

I am using the Terracycle idler to set chain tension since it can be slid up or down the tube it is attached to.

Do you find the frame flexes enough to affect tension? I have seen others write that the Xtracycle frame ( Even the Dummy ) has enough flex over that long length to require active lenght control, ( i.e. spring tension. )

With my BD I have only noticed some side to side flex when heavily loaded, nothing that would affect the chain tension.

John,
Are you pretty happy with this setup? Is it pretty well constructed? The extra chain wrap seems to be a nice plus.

Too funny that h-a-o-l-e was edited. Perhaps the server for this site is in Hawaii, and it is a bit sensitive to that word
It's official: I've gone Dummy Crazy. Had my first Big Dummy dream last night. Popped into my local bike shop and was delighted to discover they now stock the entire line of extracycle rack accessories. SO great! Then I woke up, and had to come to terms with the sad fact that it was all a dream
I think I am going to go for broke and get the Rohloff hub. I've read a million good things about it, and only 1 slight negative (I guess the thing can be a bit noisy in 7th gear?). The plan is to have a garage sale, and to scrimp and save like a madman! I'll be trolling ebay for used hubs - anyone out there purchase a used Rohloff? If so, what should I be looking for?
Mahalo!

Hey John
Any chances you have some pictures of your set up. Particularly of the idler and rohloff.
Ive been running a regular drive train with my dummy for 2 years and its been great but now that i busted my hub i may finally spring for my dream rohloff. The idea of the idler seems great. I was hoping to figure out a way to possibly do away with a low mounted tensioner. I also have a kickback and there are known problems with it and not having enough clearance with the rohloff tensioner.
Thanks for any help!!
Joel.

Hey John
Thanks for the pictures! Looks great. I think ive almost made up my mind about rohloffing! Just have another quick few questions.
Do you see any problems with durability in the terracycle idler? I plan on using the dummy for a long tour and i want the idler to last! Im unfamiliar with how the idler even works?
How do you remove the wheel? Do you release tension on the idler or can you just take it out?
Any other issues you have come across?
Thanks for the help!!!

Two very important things happened today:
1) I test rode a Big Dummy for the first time. Pure bliss.
2) I put a deposit down for a 2011 Big Dummy complete build. Hopefully I'll get in on the first shipment of new bikes - fingers are firmly crossed!
