On behalf of the German republic, I thank you for your business.

Also, that is a great looking bike. That head tube looks to be 25cm high!

Thanks Flax, stuck with crank problems for this bike

The rohloff needs a 52 or 53mm chainline, about the spot of the big ring on a MTB crank. The problem is that I don't want a super wide Q factor. I think I am going to get some dura ace 7600 track cranks and run them on a longer square taper spindle.

The only place I can find 175mm 7600 track cranks in japan of coarse, so I guess I will have to order those.

I need the cranks so that I can install the drivetrain so that I can fit the fenders.

Wish I could help, but those are cranks that have never seen my parts bin.

Ryan, when I set up my Big Dummy with the Rohloff initially I used some 9 speed 105 cranks with the ring in the big ring position and I think it gave me the proper chainline. I didn't have the Rohloff on there for long so this is from memory. IIRC the BB was a Phil Wood 116. IIRC I used some of Sheldon's tables to figure the correct BB axle length/

That is a pretty good option, any square taper road cranks with a longer spindle will do the job, the track cranks I am after should net a narrower Q factor though, road cranks have more room between the big ring and crank arm for front derailleur clearance, Track cranks don't.

I'm not sure if this helps, but this site shows some lower Q track cranks thanks Shimano:

http://businesscycles.com/tr-refspec.htm

Specifically Campy Record and Miche Primato Pista.

Of course, the other low Q SS crank is Herse. 🤑

What about a Stronglight 49d? The big ring sits relatively close to the crank arm.

That could be an ok set up as well, I have some ta cyclotourists around, need a 125mm spindle though

Campy track cranks would work as well but prefer a jis spindle , I have a lot of jis bbs

True, finding the correct asymmetrical spindle is another issue, but they're out there. A spindle intended for a tandem should be close. Velo Orange and Shimano sell 124mm and 127mm cartridge BBs, but not sure what the offset is.

To play devil's advocate, how about getting the chainline "close" but maybe not all the way out there and using an 11s chain? In theory you're going to wear out the chainring, cog and chain faster than an optimal chainline, but I doubt it's really that big a deal in practice.

I'm anti assym bb.

I'm not overly concerned with perfect chainline, as long as it runs quietly .
