Better uphill Gearing
So I have a Tri event coming up in a little over a week.. as I mapped out the course, I noticed the climb was a little longer with elevation than I expected. About 2 mile +8 -to 9%
I have a Giant TCR Composite 2 w/ 9 speed Shimano Ultegra Components. I'm not an expert cyclist, so I apologize If I'm missing any crucial info.
I just put a 12-27 cassette on in place of the 11-23. The chainring is 53/39. My rear derailleur is an Ultegra RD-6500 which will only go up to 27/28 if I recall.
So.. advise if I want to get some better hill climbing gears. Can I try a 12-30 cassette (squeeze it in)? Do I need to get a pickup a different derailleur and get maybe a 12-34. Or.. different chainring?
Trying to determine best course of action and parts needed as this is getting close.
