Personally I wouldnt bother changing it. OK - so you don't use the granny ring, but its gonna cost a fair bit to buy a new chainset. Cant see theres that much benefit to be had by going to the double either. Wait til your dad gets a bike with a double chainset and swap them over ?? ;-)0

Just undo the bolts and take the granny ring off.
No other changes required, apart from screwing in the front mech limit stop a bit.0 -
You need the chainset itself (rings and cranks), the external bearing cups, which are sold separately, and probably a new front derailleur. I converted from a 105 triple to compact double and that's what I had to buy.0

But you need to be a bit careful because if the chain is stretched you'll find it jumping when you give it a bit of stick. In which case you'll need to replace the chain and cassette as well.
Why not spend the money on a cycle computer with a cadence meter? It will make more of a diference to your riding abilities than losing a granny ring will.
When the chainset is knackered then replace the whole lot with what you want.0 -
What a bizarre point. If the chain is so worn that it jumps on a new chainset then it's well past the point it should have been changed anyway, so that's hardly an extra expense.danseur wrote:But you need to be a bit careful because if the chain is stretched you'll find it jumping when you give it a bit of stick.
