Would you put one of these on your Tikit?

No I wouldn’t put a Rohloff on my Tikit. I don’t need more than the gear range of a Nexus 8/Alfine on that bike, most of my Tikit trips are shot utility rides so my mileage isn’t enough to justify a really log lasting drivetrain and the whole bike is worth less than the cost of a Rohloff so it doesn’t make sense from a cost perspective.

Even the music is like seventies p0rn :).

Vik,
I am considering a Catrike with a Rohloff hub installed on it.
I have a couple of questions for you:
1. In the Co-Motion Americano 2010 Rohloff, they use a 42T chain ring. What would you recommend as good chain ring setup for a Catrike (20″ front wheels and a 26″ rear wheel). Is there a scientific way to figure these things out?
2. What are your thoughts on Schlumpf High Speed drives?

Peace :)
-Chandra…

PS. Is this the best way to contact you?

You can email me at threeohm “at” gmail “dot” com if you like or just leave comments here – your choice.

Well first off you can’t use a chainring less than 38T with a 16T rear cog and still get a warranty. You can go lower than 38T and not worry about the warranty or lie to Rohloff if you have a problem. I’m not going to get into the morality of lying to a manufacturer.

Personally I’d go with a 38T ring up front and be happy with the resulting 17″ – 90.6″ gear range with a 26″ drive wheel.

I’ve never used a Schlumpf HSD or Mtn drive. The mtn drive will likely void the warranty on a Rohloff just like using a small front ring. Given a high gear of 90.6″ just with a Rohloff [16T x 38T] I personally wouldn’t want any higher gears as pedaling @ 100rpm will give me over 45KPH. I’m not likely to exceed that except downhill at which point I’m happy to coast.

Since installing the Schlumpf HSD requires permanent modification to your BB shell I would at least try the Rohloff out alone first. You can always add the HSD later if you feel the need.

Thanks, Vik! What you say about thte Schlumpf makes sense. If I decide to go this route, I will check out the Rohloff standalone before adding the Schlumpf.

Peace :)
