13238Re: Xtracycle, nuvinci, kickback, and chain routing
- Mar 31, 2011I spent a lot of time trying to "fix" the chainline on my wife's big dummy w/kickback/nuvinci/stokemonkey.
Between the shop and myself we tried different chain tensioners, different size freewheels, different chainrings.
In the end, I got it "close enough" and quit working on it. I had the added challenge of a stokemonkey though, which caused additional clearance issues. The chain rubs lightly on the underside of the kickback.
Once I realized how much I hated the Nuvinci I quit trying to make it work. The plan was to rebuild it with either a Rohloff or derailleur. My wife had a bad wreck though and knee surgery so it's been put off for a year. It's about time to start work again.
[shameless ad] If anyone's interested in a Nuvinci (1st gen) wheel let me know.
