Brain, I have such a crush on this bike it’s embarrassing. The paint job specifically breaks my heart.
Please could tell me what tyres these are? I see you run them on most bikes.

In reply to Mateo. Hi Mateo, the setup with this circuit only worked with the original Dura Ace Di2. I think The Sinewave Cycles Revolution is a fine option for modern Di2 but charging with the lights on might require some fast speeds. Good luck.

Hello Mr Chapman. Could you elaborate on the wiring and details for the Di2/Dynamo Setup? i’m thinking of getting my bike built along these lines, but maybe using a Sinewave revo instead of the e-werk, and a couple supernova lights with a switch

In reply to Pete. The rear hub is a White Industries MI5. And I love the 650b tire size! I went from 28mm road tires so it was a dramatic change. These wheels allow me to go places I never could on 28mm tires. If it was to be strictly a road bike, I'd probably stick with 700x28c tires though.

What rear hub are you using? Also, how do you like the 650b tire size? Any noticeable downside/upsides from riding them? Future bike research…Been dreaming of having a bike like this for years. Such a good looking machine!

In reply to Yves.

Hi Yves,

Thanks! And yes, there is a small circuit that is required for the charging. I’ve been using it for the past 6 years with no charging but I’m hesitant to encourage others to make one! 🙂

Take care,
Brian

Hi Brian,

this is an amazing bike. Do you need a charge controller or something similar for charging the DI2 battery pack? I absolutely love the combination of classic lugged steel, 650B tires and modern components.

In reply to Tom B. Hi Tom, Thanks for the kind words! The BB shell is the Pacenti for 22.2mm round stays. I think Spectrum is selling them now. The ports are very close to the faces. That with 435mm stays and a dimple are plenty for 42mm tires.
