May be it depends of the tyre. I use Schwalbe Kojak, and you use Schwalbe Marathon that seem to be bigger diameter than the kojak ones. Anyway, the gap between 1st and 2th gear is too much high. Regards. Hydra Hi Steve

Thanks for your quick reply. Unfortunattely, I have already bought the SD with 16" wheels. As my city is absolutly flat, I will go for the 18" wheels upgrade kit. So, I will get my old ratio in the first gear, and I will ride quicker than Lance Armstrong in the second one ;). Regards. Hydra. Hi Steve.

There were both many requests for a gear low enough to climb steep hills and for a gear tall enough for good top end speed. This would be pretty easy to achieve with a multiple gear setup, and of course the jump between gears wouldn't be so significant. When there are only two gears the difference will be beyond subtle. If you like the original Strida ratio, you will like the low on the SD with 18" wheels, as it the same. If you are thinking that the tall gear on the 16" is already high, it is even more so (12 1/2%) with 18" wheels. Personally, I like the SD with 18"; I shift out of 1st rather quickly,then I enjoy the speed in 2nd and can cover longer distances more easily. If I encounter a long route with a steep enough incline, it can get tiring. So, I can always drop back down to 1st. I would check with your retailer and borrow an SD with 18" wheels before you buy. -Steve Hydra,

I have bought a new SD, and I think the ratio speed is not very well ballanced. The lower speed is too much low while the second gear is high. I miss the well ballanced ratio of the original Strida between the new first and second gears. I am thinking to improve the SD with 18" wheels, so, I would get the original ratio again for the first gear, although I think the new second gear would be too much high and difficult for normal use. What do you think about it? How hard is the second gear with 18" wheels? Best regards. Hydra Hi again, Steve.

We are currently sold out, having sent our last set to Chile. We are expecting them in two weeks. Correction, they have just arrived and can be ordered here. Please choose $USD or $CDA currency.

Instead of just a button as provided by Schlumpf on the Speed Drive, the Sport Duo has a plate on top of the button, covering the length of the crank. this plate makes changing gears easier, allowing you to use any part of your foot. It is most practical however, to change when the heel is in the back (3 O'clock) position. Then it is a very simple tap motion with the heel.

How does work the change of speed? Can you change in movement, in any moment, in any pedal positionO? or must you change when the heel is in the maximum back position? (horizontal-back pedal, no pedal movement) Hi.

I think they have kits for Bromptons already. I recall that it is something like $400USD for the drive alone. For the same $400, the Strida Sport Duo gives you the drive, alloy pedals, alloy belt-wheel and alloy freewheel. -Steve I can likely source the mechanism from Schlumpf, if there is enough demand for it from Strida owners.

(i like the small size).
