I've worked out the various gear ratios that come with the standard version of the 2006 Giant TCR 2 (which I've more or less now decided that I'm going to get)
Shimano Ultegra components 52/39/30 up front and 10 speed 12-25 cassette are the standard components coming with this bike.
My question concerns the possibility of damaging the teeth through potential cross chaining. Imagine cycling along in 52x16 - I believe this would give 88 gear inches. Now if I wanted to shift down into 52x17, (giving 83 gear inches) it would mean moving towards the 6th sprocket on the cassette (I don't know if it's actually called the 6th sprocket - I think of 12 as being the 1st sprocket, 13 the 2nd, etc. I may have got this the wrong way around in cycling parlance).
On a 10 speed cassette this would mean moving the chain onto the second-half of the cassette's range. Could one get away with doing this without any damage and loss of pedalling efficiency?
Many thanks
