Well, the tyre appears to be quite tight on the rim and was a bit of a bugger to remove and replace. This led me to think that maybe the rims on the Cannondale might be a tad bigger than normal or the tyre might be a smiggin too small for the rim. I have not had time to measure things out just yet but it made me think that perhaps there is a reason for slightly larger rims or slightly smaller tyres. Is there? I have one plastic lever (has clip molded on) clipped on the seat tube - has never failed. Well, if you only ever use your hands to remove and replace tyres, that lever ain't NEVER gonna fail, eh? I'm not as look as I'm dumb Although ..... You mean you are as not as green as you are cabbage lookin. Ah Ah I just discovered sumpin, when I put colon half bracket it turns into a smiley. |

I have a pair of Zipp wheels that seem to be a bit bigger than other rims I have. Moved tyres from some Velocity rims to the Zipps (and vice versa). Zipps definitely more of a challenge. I don't think it's due to the internal depth of the rim, but I'm definitely not taking the tyres off to check. Trying to work out how I'd measure the diameter accurately... Worked out how to do that. Same was as you measure the height of your children - stand on floor, mark on wall... Hm.. (rim+tyre)-(rim alone)=tyre ... external diameters only of cos. Internal diameters? Not too sure .. the tyre by itself would be a bit too floppy, wouldn't it? |

I bought some smooth tyres that were definitely too small to replace my cross country tyres had a bugger of a time tryiny to fit them then took back and asked would they fit them - finally come home with another brand - cos I would never be able to remove them on the road to make a repair. Going by what you said about x-country tyres, I am assuming you had a mountain bike rim which would take 26" tyres, so did the smaller tyres, which didn't fit, have 26" markings? If so, it would suggest that some tyres are really what they seem, eh? The current tyres on the Cannondale do say 700Cx23 but I am suspicious of the actual measurements due to the tightness on the rim - after all the piece of crap (POC) I normally ride seem to have tyres which slip on quite easily onto the crappy rims the POC has (this is of cos academic at the moment becos the POC is still hors de combat - you know, the rear derailleur problem?). |

You derailler problem - what brand do you have? as there maybe an old used one,(could be bent not worn out) in the parts box that has come off the trials bike. I think its a short road type with not a hugh amount of selection range 6-7 cluster which may work with your selector. |

Thanks for the offer matey but I don't think a derailleur from a trials bike would fit the road bike. I currently have a Shimano which is broken and bent. I'll probably drop by Maroubra Cyclery later on this week to get a Suntour 7-speed derailleur. I think they are $40 a pop so that's good value. Might replace the front derailleur as well. Thanks again for your kind offer |

The type used the short on off a road bike and what maybe there is a Shimano as I don't think any other brand has been used. They have now developed a fixed type of chain tension device as using a derailleur is not in the rules. That's why its now in the bin of bits. Oh well !!!!! |

If the front derailleur is working OK, DO NOT REPLACE IT. I'm still using a 30 year old Suntour Cyclone front der on one bike. It's good as possible! |

Hm, sorry, rob, now that you mentioned it, I think I am confusing a trials bike with a mountain bike - goes to show what an amatuer I am, eh? Would you be meaning a time trial bike? If you are, I am pretty sure your derailluer would probably be waaayyy too good for my crappy road bike and I would feel guilty taking it from you unless you allow me to pay you a token sum. They have now developed a fixed type of chain tension device as using a derailleur is not in the rules. That's why its now in the bin of bits. I am rather green where trials bikes are concerned so maybe a bit of reading on my part would not go astray. I'll ask me mate, Google |
