Was about to buy an EVO, would love a C1 but it has no gearing & for a hard rider, I need gears. Own a couple of SX’s, true racing Stridas but for the gears. Reluctant to invest $1300 for an EVO, then $200 in pedal upgrades, etc. Was searching on craigslist for used stridas and found a link for ebay stidas and then speed drives/gearing. Which one would you guys recommend, they are Taiwanese but say they are the same German engineering? Do I need to replace more than just the $280 components? Is it complicated, could a bike store do it or do they need specialized tools & parts? Here they are, all 3 seem slightly different; This one is for $280 [ebay.com/itm/Schlumpf-Speed- … SwCQNWf4v7](http://www.ebay.com/itm/Schlumpf-Speed-Drive-Crankset-Strida-Upgrade-Kit-Heel-kick-shift-2-speed-ATS-/191702265594?hash=item2ca2586efa:g:dHIAAOSwCQNWf4v7) This is for $400 but seems to have a whole lot more [ebay.com/itm/Schlumpf-Speed- … SwmrlUugHw](http://www.ebay.com/itm/Schlumpf-Speed-Drive-crankset-for-STRIDA-Two-speeds-170mm-Folding-bike-/301491338172?hash=item463248bbbc:g:WbgAAOSwmrlUugHw) This one is for $480 but it talks about an ebike application [ebay.com/itm/Schlumpf-Speed- … 1491338172](http://www.ebay.com/itm/Schlumpf-Speed-Drive-Extended-Bottom-Bracket-100mm-E-Bike-Electric-BIKE-ATS/191856644445?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D37183%26meid%3D15b373bae4d14a3781bf15d36df18a6c%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D301491338172) Has anyone had any recent experience with these companies?

For this reason we decided to produce a tailor-made alternative including the excentric fitting for the Strida, which is now available and works faultlessly. However, with “made in Switzerland” and 5 years full warranty this part is also a little more expensive.” From here: [Re: Has anyone retrofitted a schlumpf on their strida?](https://www.stridaforum.com/t/photos-of-stridas-in-hong-kong/23/1) > [@Doctor Strida](#): > > Do I need to replace more than just the $280 components? If you mean your first two links: They seem to be complete, but without tools. The third link is a longer version which is not suitable for Strida (no beltwheel, no belt, no eccentric bottom bracket). > [@Doctor Strida](#): > > Is it complicated… I’ve done a lot of work just to help Strida riders to judge about this delicate and personal question. [Re: Has anyone retrofitted a schlumpf on their strida?](http://www.stridaforum.com/forum/viewtopic.php?f=2&t=2751&&start=45#p7258) Nobody else than YOU can tell if it will be complicated for YOU. > [@Doctor Strida](#): > > …could a bike store do it or do they need specialized tools & parts? An experienced shop must be able to do; they will already own most of the required tools. > [@Doctor Strida](#): > > Has anyone had any recent experience with these companies? Just a short, not productive mail contact with bikegang. > [@Doctor Strida](#): > > Does it make that much of a difference, having a second gear? My opinion telegram style: One gear - much too less. Two gears, heel gear shift - cool, but still too less. Three gears, backwards pedaling gear shift - not my style, well, Ok… Seven gears - now we’re talking 🙂 > [@Doctor Strida](#): > > What are the real advantages? Shifting by heel kick during pedaling forwards. 🕶 ---

As always, a fantastic answer from Blackstridaaustria! While I can do almost anything, it seems; At $400 for a Taiwanese kit Without buying the specialised tools Then the Labour costs It’s much cheaper to buy an EVO. Moreover after reading what the inventor suggests, deep in those threads, about $650 plus, it makes even less sense. THANK YOU!
