And did you guys know switching the cog and the chainwheel around(small in front and big in back) Creates a unique 5:1 ratio. Super easy to pedal, but you go super fast, they call those fixie bikes. -- SHAY_CAM Bringing back the Bmx style unicycle. ------------------------------------------------------------------------ SHAY_CAM's Profile: http://www.unicyclist.com/profile/16229 View this thread: http://www.unicyclist.com/thread/73977 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Super easy to pedal, but you go super fast, they call those fixie bikes. a ratio that way round would be easy to pedal, but extremley slow, infact 25 times slower than the other way round. And a fixie refers to a hub with no freewheel or ratchet, the gearing has nothing to do with it. And you can't just swap gears front and back, the interfaces are different. And chainring and sproket are perfectly acceptable words for the equipment we're discussing here. -- kington99 Dave - what a thoroughly post-modern subversion of the cycling genre - ------------------------------------------------------------------------ kington99's Profile: http://www.unicyclist.com/profile/9417 View this thread: http://www.unicyclist.com/thread/73977 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Chainwheels for the plate style rings that BMX bikes typically use. Chainring for the more ringlike rings that road bikes typically use.

The 2009 Schlumpf Speed Drive has a new clutch design that can be used with a fixie bike. I don't see info about the new designs on the Schlumpf web site yet. There is a brief mention at Velovision: 'Schlumpf's new drives' (http://tinyurl.com/6zeemp) Neat stuff. I'm going to have to start thinking about a multi-speed fixie. -- john_childs john_childs (att) hotmail (dott) com Team Never Wash Your Muni 'My Gallery' (http://tinyurl.com/3d57bn) :: 'Unicycling Bookmark List' (http://backcountry.unicyclist.com/) :: 'World Clock' (http://tinyurl.com/2blym3) ------------------------------------------------------------------------ john_childs's Profile: http://www.unicyclist.com/profile/449 View this thread: http://www.unicyclist.com/thread/73977 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |
