Mongoose Randonneur owners - how's the ride?
Aaaah, what's bubelrocks, you ask! Nothing to do with Michael Buble Prnc (try saying "prince" without any vowels) Bubelbubel is an altereg of mine, of mysterious origin. He attempts to find the meaning of lif by contemplating rocks, and their byproducts, such as bicycles. A bi thick really, tends to forget about humans... I don't think you want t know any more Thanks so much guys, for teaching me the "google groups" method o searching. I have found a few more posts on the randonneur, though thi thread is now the most helpful, and I hope it keeps going a bit The only thing that's worrying me about the Randonneur is that it seem to be a car magnet! Perhaps it's the dark colours.. I'm interested, Adam, that you've changed to a 9-speed cassette whil keeping the crank from the 8-speed setup. I thought cranks were eithe 8-speed or 9-speed (though this is a vague thought, like most of m bicycle knowledge). Any problems with the chain, shifting etc? : -- bubelrocks |

There's no issue with running a 9 speed chain on the 8 speed chainrings but technically 9 speed chainrings are mounted slightly closer together. I am using a 9 speed STI shifter with 8 speed spaced chainrings but there must be bugger all difference in the amount of cable pulled by the shifters as it shifts fine. Here's a few snippets on chains I've cutnpasted from the Barnett maintenance manual pdfs I downloaded from the web: "The nine speed chain has an outside width of approximately 6.6-6.8mm, ..5mm less than any other type of chain. This narrower width allows the cogs on a nine speed rear cog set to be spaced much closer together, so that the nine cogs fit in almost the same total space as eight cogs. Shimano nine speed chainrings spacing has been reduced and the width of the front derailleur cage has been reduced as well. The narrower chain is still close enough to the dimensions of other derailleur chains that it fits eight-speed and lesser configurations.....The nine speed chain can be used with other than nine-speed chainrings and front derailleurs. Due to design differences more than dimension differences, performance might be slightly compromised, but this combination will be functional." -- adam85 |
