Cassette Advice Please?

Looking for some advice on purchasing a new cassette for my P2 for IMMOO. I can't seem to find the numbers, but believe the standard cassette it comes with is the 11/25 and am considering the 12/23. When shifting in my middle gears, I notice the difference and can't find that sweet spot where I'm not working too hard or spinning at too high of a cadence.  I love spinning out on the downhills, but really think I can gain some time throughout the other 95% of the course.  Thoughts?  Do I need to buy a new chain as well?

    I would go with the 11, not the 12, you will give up lots of speed by spinning out too early. Unless you have a really high w/kg I would stick with at least the 25. Coach Rich is a big fan of the 11-26 which is what I run as well. Many other ENers do an 11-28. With the 28 you will have more cadence gaps but might find it easier to flatten the course and keep your VI low. You should not need a new chain.

    Peter; thanks for your response. I pulled the trigger on a 11-28 - think it could be a game changer for me on this course.

    11-28 ... Peter wins! :) that course is just so hilly unit has plenty of places where you can really dialing the teaching time. 11-28 will allow you to do just that, and by getting it now you'll have plenty of time to sort it out before the race comes. I got one this year, and it's been a total game changer for me.
