Sunday Sept. 22nd. 2019. Although we really like the way the NuVinci N330 CVT Internal Gear Hub on the rear end works, it's pretty limited "gearing wise" especially for "HILLS"! We'd hoped to be able to afford adding a E-assist motor system but a set up heavy duty enough for our tandem trike is $2800.00 or more!!! :O We decided to try changing it to a "Rear derailleur/Cassette set up", the cassette is a 10 speed with 11x42 tooth cogs! Yes, it was worth the $750 price tag (parts and labor) as it is now easier to make the tandem climb hills and uphill grades, YEA!!!
LOL, NO it won't make us a bit faster on the flats so we still won't be able to do any "Group Rides", unless the fellow riders don't mind us taking up the rear of the pack and coming in at our own pace!! Still we are both 64 years old with some medical problems so ANYTHING that makes it physically easier for us to climb hills is a real blessing!! Our new drive train is: (front) Efneo 3 speed, Internal Gear drive unit, equal to a "triple chain wheel set" of 28/40/52 with the 11x42 rear cassette. We took it for a test run on some of the more HILLY parts of three of our local urban trails, "Sinton, Foothills and Mesa" Trails here in Colorado Springs, CO. It was a lot easier to get up the grades than before so we are quite happy!! The first photo is on the Foothills Trail, just outside of the Garden of the Gods, the second photo is at the Mesa Rd. Overlook just off the Mesa Trail! :)
