Big newbie,,,.. But love the bike!booze18

Largest Rear Cog 25
Number of Rear Cogs 9-speed

Rear Cogs 9-speed, 12 - 25 teeth
Rear Derailleur Shimano 105 SS

Just bought a Giant Aero TCR 2 . I am so used 2 riding mtn bikes, im not used to the ring set up with the giant while trying 2 climb some hills. With the mountian bike of course it has the three ring granny, climb anything ratio. With some of the hills in hawaii there's no way i could climb the hills with the current set up on the Giant Aero 2? What's the magic set up? Thanks in advance

Hey, I'm in the same position as you. You could try and replace the front crankset with a triple setup if it's not already there, or get a rear cogset with more teeth. personally I use a 25tooth in the largest rear, but you can find them up to 28 i think.

anyone correct me if i'm wrong please!!

I bought my bike with a 53/39 & 11-22. I found that I needed some smaller gears. I found that it would cost a lot to replace a crank and setup the bike for a triple--plus, its not an easy install. So I decided to buy a 13-28 cassette in the back. That cost me $34 (Campy Veloce), and is enough to let me spin up anything we have around here--Illinois. You've got mountains though in Hawaii, so perhaps that won't be enough for you. Have you talked to the shop where you bought the bike yet? They may be willing to cut you a deal on an upgrade to a triple.
See if your shop will swap out the double crank.............MR_GRUMPY

....for a triple crank. You could also try a 12-27 cassette, but it won't be a "Giant" difference. (joke)

you may want to try a mtn bike cassette and an xt rear derailleur.

cheaper than new chainrings and shifters.

I have a Giant TCR2 (non aero) with the same gearing setup.

You'll find the lower gears on the smaller chainring are
plenty adequate for getting up big hills but really steep
hills may call for a triple chainring.

Consult your local bike shop to see if this is necessary.
I have not done this - the double works for me but I've got
almost 1500 miles on the bike and like the way it works as
is.
