52 vs. 53 Big Ring(12 posts)

52 vs. 53 Big RingI Love Shimano
Aug 28, 2001 1:13 AM
I'm a newbie, but am planning to train seriously and eventually, race. I currently run a 52 teeth big ring and a 13-23 cassette on my 105 9 speed. Should I change to a 53 teeth ring and a casette with an 11 or 12 tooth cog once my equipment wears out?

Switch the large chainring to a 53. This is a common setup for racing and you'll benefit from it for all but your largest cog on the cassette. With the cassette, wait until you start racing to decide if you need the 11 or 12 cogs. I have an 11-23 cassette, and my 11 and 12's rarely are used. Typically the 11 and 12 cogs are used on fast descents, so check out the course profile to verify the need for them. If you develop an efficient pedal stroke and can mash big gears, the smaller cogs will be needed, but wait on it for now.

I would first say change the cassette. But as far as the chainring goes, it all depends on what your leg speed is. Most riders do go with the 53 now. It is pretty much stock size on cranks. But, you may want to consider a few things. Fred Rodriquez uses a 54tooth ring, and Tom Steels uses a 52. Both excellent sprinters and booth using different sizes. Steels has a fast leg turnover according to Fred.
I just think that last two resonses are a little quick in their decision making process. I 1 tooth change in the front is going to make a greater change then the same in the rear. I highly doubt you're going to be getting "out spun" with a 52 vs a 53. I would say try the rear cassette first and see how that works for you. I hit my 12 and 11 a decent amount of times in crits and hard training rides. So it is really all dependent on your riding style.

Excuse me, but how on earth did you come up with "1 tooth change in the front is going to make a greater change than the same in the rear." 53/52 = 1.019 (1.9% change), 13/12 = 1.083 (8.3% change). All that said, once you can spin out the 52/13 (34 mph at 110 rpm), then you should worry about a bigger CR or a 12 or 11 in the back. Very few riders can actually turn over such combinations. Most people should work on their spin and technique rather than thinking they can buy speed with higher gears.

What I am saying is that by changing 1 tooth up front, you are going to be affecting a lot more changes in your gear ratios (all 9 gears). You will be adding to everything in the range, while the 1 tooth drop in the rear will only affect a combination of two gears either the 39 or the 52.

I'd leave them alone for the time being and learn to spin like he!! with the gears you got. By the time you can spin out a 52x13 on anything less than a steep descent you will have worn out your rear cogs. Winning is less about buying stuff than it is about developing fitness and skill. The discipline of not replacing what still works helps pay those entry fees.

You got it man. I know guys who can kick butt on bikes built in the 70's. It's all about training like a maniac and learning how to ride properly. On the other hand, its nice to know these things for the day I might actually be in a competetive situation.

Time after time Armstrong beat me to the line...then, WAHAHA, I swapped my 52 for a 53. Now the druggie sees nothing except my behind.
You guys are getting me wrong....I Love Shimano

I don't want to get a 53 ring to instantly make me faster. I was asking for opinions on whether it was a good idea to get a 53 when my 52 WEARS out. I am insulted by the fact that you all thought I believed I would be faster if I bought a 53. Tsktsk

The reason why you're running a 52 on your 105 is b/c it's a triple - correct? One of the reasons why a 52 is used instead of a 53 is for the max. range and capacity of the front and rear der. My guess is that by the time you do enter your first race you won't be running a triple, but I could be wrong (of course!)
