Long time MTB'er now with my first good road bike, new to forum, have question.
Hello all. I'm 53, semi-in-shape, and new to road biking. I rode a road bike when I was a kid but it was a steel tubed cheapie. My new bike is a 2011 Trek Madone 5.2 with the triple crank option. I live in a pretty hilly area, California Central Coast, and even with the triple crank, at times I could use a few more teeth in the cassette. I currently am running the stock 11-28 105 cassette. Could I use a 11-32 xt cassette without having to change my derailer? Is there another cassette option that would work? I'm guessing I'd have to replace my chain too?
Thanks for any replys. I'm really loving getting back on the roads.

Someone will correct me if i'm wrong but i think, as long as the brand is compatible, you can have any tooth configuration you like on your cassette. Of course, if you are running 9 speed shifters you need to stick with 9 speed cassettes etc. and that will determine your chain too, 9 speed chain on 9 speed cassette.

I think it probably won't work, assuming you have a 105 rear derailleur. But I think it depends on exactly which model. Rear derailleur specs usually include a minimum and maximum sprocket. Here's a 105 rear that says it's limited to 11-28. And here's an XT rear that says it can go from 11-36.
When I lived in Seattle I had a 14-32 freewheel on my road bike. That low gear was great on those hills.

A new mountain bike derailer will make life much easier, however.
Keep all the old parts - at least initially - in case you have to change back.

You many find compatibility issues trying to run 10 speed road with 10 speed Dyna-Sys (Shimano mtb).
Shimano do a 12-30 in the 4600 Tiagra range; SRAM do a 11-32 in the Apex range, you will probably need to change you RD if it is a short cage, as these as spec'd or 11-28t (which is another option), the long cage can handle the 32t, a new chain would be needed if you went for a larger cassette.

Probably can't. The Ultegra has a inner BCD of 92 mm which is too large for a 24 tooth inner.
