12-23 vs. 12-25 need advice???Road Classic
May 28, 2002 7:18 AM

I am trying to decide whether I should move from a 12-23 to a 12-25, I seem to ride my 16 a fair bit....will I miss it? Any advice would be great!

What kind of riding do you do and why are you contemplating the switch?

My riding is for the most part fairly hilly and when it isn't I look for the hills. I ride with a cadence between 100-110 and tip the scale at 154ish pounds, it just feels like gear smashing in my 21 or 23 on steep terrain, cadence down in the 80's or even high 60's. However, the climbs are not long long, just often.

thanks for the advice.,

If doing a lot of hills, save the knees 12-25 way to go (NM)Paul

Do you need the 25?DMoore

If you do, that answers the question. If you don't, why bother?

The answer varies greatly from person to person. I ride an 11-23 full time, including mountain rides with 5000' of climbing. I switch to a 12-25 for one ride each year - a mountain century with over 9000' of climbing. I've never actually used my 25 on that ride, but it just makes me feel better knowing it's there if I need it.

OTOH, some of my friends use 29's on that same ride. It depends entirely on you, your riding style and your strengths and weaknesses. If you use your 23 a bit, and find yourself wishing for something lower, then you need to change your cogs. You'll learn to live without the 16 if you need that 25!
Use the 23 much?jw25

I run 12-25's on both wheelsets, but tend not to use the 25 much at all. It's a bailout gear, but most climbing rides around here don't have the super-long grinds that kill your legs. If you like the 16, and aren't wishing for a bigger cog to make a climb, stick with the 12-23.
I'm in central PA, 145 lbs, try to spin around 100 rpm, but climbing, I'll drop to 70-80.

Yes I do use my 23, I like to keep my spin as high as possible, above 80 if I can on the climbs; however, my 21-23 puts me 70-85. I live in Calgary Alberta, thanks for the advice...
