rear derailleur and friction shifting
Will any derailleur span through the 10 speed cassette range in friction mode? Im not asking about whether or not it is difficult or possible to shift. I want to know if it will be able to move between the largest and lowest cog. Wondering if limit screws will interfere with the range.

Thnxs I don't KNOW the answer, but I would be rather surprised if you couldn't get across 10 cogs (or 11) with anything made post-1970, and quite possibly earlier. If the limit screws get in the way, just remove them. |

A Svelto for example with the screws removed completely will need a touch with a file to do seven speeds. I remember pulling one screw and adjusting the stop with a hammer, I don't now recall which end (it's only for winter use and my legs haven't been able). Ever thought of filing and drilling the Svelto and getting it on the scales? |

yeah the Raleigh rebuilt to modern specs has friction shofters from 78 n there's a set of those indexed friction shifters in the box.
Using 8 speeds on a cassette not the OEM freewhell there's one gear left fersure...like how wide is a ten compared to an 8 or 9... I haven't ridden it in 3.5 years being away....maybe true that it is adjusted to ignore the small 13/14 first hi cog. ??? measure ! there are other posts on this in RBT try a search |

Andy - izzit possible to mount a larger wheel on the friction shifters thus ??? allowing a longer rear throw ?

I want to know if it will be able to move between the largest and lowest cog. Wondering if limit screws will interfere with the range. Thnxs "In friction mode?" If you mean using friction shifters, like bar end shifters, with a 10 speed cassette, why not? the distance from the small to large cog is the same as on a 9 speed cassette. It is the distance between the cogs that is different. And, yes friction shifters will certainly shift 10 speeds very well. In fact with friction shifters I can switch wheels, one with a 9 speed cassette and one with a 10 speed cassette and not have to make any adjustments at all. No change in limit stops whatsoever. -- Cheers, John B. |

If it is a modern derailer then it has sufficient range - a 9 speed and 10 speed cassette are the same width. If an older 5 or 7 speed derailer then possibly not. -- Cheers, John B. |

Or use an aftermarket cable leverage enhancer: http://farm4.staticflickr.com/3072/2...1f2_z.jpg?zz=1 -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

cool but another name ? bicycle: (control) cable enhancer stumps Google Patents.
the diagram is a larger wheel without a larger wheel...but drilling a hole weakens the down tube ? I was thinking...without seeing the unit before me...fabricate from strap a different lever mount then screw a larger wheel...see Global Spec...or your local sewing machine to the new rod ura gonna drill thru both levers. an hour after dinner no prob. yeah I maybe remeber I cut out the small hi gear cog for 8-1=7 for a ten speed SUNTOUR + friction lever butnot the indexed model |
