Hi,

100t Prototype Sunstar wheel with 100t out of Aluminium.
A stainless steel disk 2 mm as BTC adapter 5x 110 to 4x110
The Schwalbe big apple I bought an they fit great, but special at the aft airpressure should not be higher than 3 bars otherwise the tire gets temporary in contact with the frame above the wheel if the road is bumpy.

Even so the Kojak look cool the big apple looks better.

Hi,

well, so you have a first gear with a development of ~ 4,8 m and a second, pretty high gear which is close to 8,0 m per crank revolution ā†’ very hard to pedal, isnā€™t it?

Thanks for teaching regarding this particular Big Apple tyre size - actually Iā€™ve failed to notice.
(Most likely Iā€™m also still paranoid about Schwalbeā€™s discontinuance of the Marathon Racer in our 18" size years ago.)

Cheers,

Chris

Hi Chris,

I like the transmission ratios the low speed is good enough to climb a bit uphill, the high one is really cool for flat. And of course both keep me trained.

Perfect!

Hi Ingo,

if you like it - then it is really perfect :mrgreen:

I love the heel kick shifting method very much, thereā€™s a bit training required, but once you got it you can shift upwards during pedaling. :wink:

Btw, your ATS drive might be happy to receive a few ml of grease once or twice per year.
Also, neither ATS nor Schlumpf drives are 100% sealed, small amounts of oil/grease next to the driveā€™s gaps are normal. Regarding information about speed drives Iā€™d highly recommend the original Schlumpf drive manuals:

Hello 2-Speed-StridaC1,

welcome at Stridaforum :smiley:

Well, you realized an interesting project!
A few details would be nice, for example;

  • Is that an aftermarket 100 teeth beltwheel?
  • Which kind of spider did you use for the beltwheel (custom made?)?
  • Were there any modifications required at the bottom bracket excenter?

Kind regards,

Chris
