Hello people,
I've been thinking of changing the crank of my Giant Defy 3, from an FSA not-sure-what-it-is-but-looks-cheap (edit: it looks like it's an FSA tempo 34/50T ) to an 105 compact double crank. The only problem is that the bike's mech is the 2300 8-speed shimano stuff, but the 105 is designed for 10 speed sets.
So, I thought of taking off the chainrings of the 105 crank and use the chainrings from my current crank. Do you think that this could work? Are chainrings for compact cranks interchangeable? They do look so in my untrained eye...
Another point I'll have to consider is changing the BB. Browsing on sagamicycle I only saw two types of BB, the "JIS" size and the "italian" size, I guess I have to go with the JIS one?
The reason I want to do this is because the current crank feels.. mushy/flexy and because further down the line I want switch to a full 105 set, but don't have the cash to do it all at once. Any insight would be welcome! Cheers!
