Our eldest son acquired an old steel frames Ricci road bike off my brother a few years ago. It's quite a nice lightweight bike - although the frame is a bit rusty and creaky. The bike is probably from the 1980s imported from a bike shop in Redruth, Cornwall by a friend of my brother. It has a Campagnolo C Record groupset, however the bolts connecting the 2 chainwheels had worked loose and my son cycled on it and bent one of the chainwheels. As he's working in Vietnam at the moment I thought I'd fix it for him. So I managed to find a new Campag Centaur chainset on the internet for £52. The C Record one was 51/39 (I think) whereas the new one is 53/39 - designed for 10 gears, rather than the Ricci's 6.
My local bike shop said they'd fit it for £20, but advised that a new chain would be a good idea as the existing one was worn and may not be big enough. Of course that meant that a new freewheel was a good idea and as 14-24 cog sets aren't made anymore they replaced it with a 6 speed 14-28 cog one. So the bike now is better both up and down hills with an improved range: 1.4 to 3.8 ratios* instead of 1.6 to 3.6. (But not as good as my road bike - 1.2 to 4.0). The gearing is spaced apart more, but only for the lower cogs, so it shouldn't make much difference to cadence.I was hoping to take the bike for a decent ride today but I can't manage to lower the saddle as the stem has welded itself to the frame! I went for a quick spin on it last night though and it's pretty smooth. I might have another go at lowering it now I've lubricated the area, but don't want to break anything.

My seat post is also welded tight to the frame and worse still, my frame is carbon. Have tried everything (save cutting seat post) but to no avail.
ReplyDeleteMaybe a new bike is in order?!
At least the height is correct for my son. It was moveable a couple of years ago. Anyway I'll leave it how it is for now
