Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Cassette Question

I Ride a RT700 (BD Purchase) with 50/34 Crank and 11/23 Ultegra cassette. I just got a new set of wheels and would like to use a different cassette size.

Where I ride, its mostly flat. What other size(s) can I use and what will be the difference?

Would a different cassette require a different DR adjustment?

Is Dura Ace 10spd fully compatible with the Ultegra?

It sounds like a lot of stupid questions but I have no idea .

Tky.

Just leave it alone. If you are in the flats and don't need lower, you have right gears.

You don't even seem to know why you'd want to change what you've got.

Shimano 10 spd cassettes are all interchangable. I would reccomend a 12-25. You should not need to change anything with your derail. If you do then the adjustments are easy.

Keep in mind that you run a small risk of needing a longer chain. Considering you run a compact the chain is long enough to wrap it.

Why are you telling him to get lower gears? Not that there's anything wrong with them, but if he rides flat and doesn't know why he wants to change, why recommend change?
