I've read that it costs about £1 per gramme to lose weight off a bike give or take the odd pound, or gramme.
Well, it tuerns out that isn't the case if you start off with an old enough bike. I'm renovating an old Peugeot road bike bit by bit (and riding it in between) The bottom bracket has been a bit rough, so I took it out for a look. It's quite pitted, so I've decided to replace it rather than re-grease it.
I haven't managed to get the fixed cup out yet (I need a big nut and bolt)but I weighed the bits I have managed to remove and they are a whopping 584g without (much) grease.
A replacement cartridge bottom bracket from Shimano is £7.99 and weighs all of 308g
If I carry on at this rate I will only need to spend just north of £300 and the bike will weigh nothing at all!
So the moral is, start with an old bike and you can make it light for next to nothing.
(and on a serious note, I need lower gearing for my level of fitness / amount of hills locally, which means I need a long cage rear mech, which will save me another 200g. Seriously, if I'm not getting home from work before I set off I will be disappointed)
