Hi,
This is probably an oft asked question, but I'm looking at upgrading my old 'winter' bike's 7sp set
to something a bit more modern, mainly so I can throw some Ergo levers on there.
At the moment, I have a fairly generic (in that I can't remember what it is) 7speed block on the
back, with a Mirage '97? rear mech. I understand the rear mech will have to (obviously) be upgraded
too. The chainset is a Mirage job of the same year, probably '97, (52,42 if that helps at all) and a
Veloce front mech, again probably 1997. Brakes are Shimano RX100s if that's relevant.
Now, what do I have to change, am I looking at replacing the whole chainset/cassette/rear hub etc? I
understand I also need 130mm between rear dropouts to fit these modern hubs in, some pointers on
where to measure ths from would be much appreciated. The frame is about 6-7 years old, Reynolds
CR(o)MO tubing.
Sorry for the incredible vagueness in my post, but this bike has sat in my shed for a long time
being neglected, I got it out the other day to clean it and decided it needed a little modernising.
Any advice will be welcomed with opened arms.
Thanks, Tom
