Advantages to using a standard crankset as opposed to a Compact 50/34 racing / traini

So I have been riding for all of six months. I have a madone 5.2 with a 50/34 crankset. I seem to be a natural spinner but when it comes to pushing harder gears not that great. So I have a few questions for you BF gurus on maybe switching to a more standard size crankset.

1) since I have only been riding a compact 50/34 since i started 6 months ago could that explain why i naturally spin alot more than a normal racer/rider?

2) using a compact 50/34 have somehow hindered me from being stronger with the harder gears than I could of been using a standard

3)If I switch to a standard crankset which I dont even know what to get, what impacts/results in my strength and speed would I see? could it actually help me, will it make me stronger/faster?

4)when i do switch how bad will i stuggle with it? am i gonna be slower at first?

anything you guys would like to add about switching pro/cons would be great.

I live in florida im a small guy if that helps the discussion

There is something you can do after installing the std. crankset on a bike that should bring you back to normal.

1. Extend right index finger.
2. Rotate wrist enough to downshift 2 gears (if in the top 1/2 of the cassette, 1 if in the bottom 1/2 of it).
3. Pedal.

I'm a flatlander with a standard double. I rarely use the 11. Or 12 for that matter.

50x11=119 gear inches

53x12=112 gear inches

I used to think it was going to be a huge difference. It's not. With a 11-28, you get a full range of gears just like a triple, that is still easily to maintain on the flats. But, having that 53 is huge for racing. That extra momentum and gearing is definitely necessary for racing, and I would never go back to anything smaller.

There's no way you're going to get gears as low as on a triple or even a typical compact double, but for flat land and racing on your average course it probably wouldn't matter. 39/28 is still 36.6 gear inches. That's still bigger than even a 34/25 (35.7). If someone uses their smallest couple 34/XX gears, jumping to 39/XX is going to be an adjustment unless you get a ridiculous MTB/Apex cassette.

I changed my crank to a standard 53/39 and use an 11-21 cassette. My average speed increased about 1.4 mph (used to have 50/34 11-25)

They should give you some sort of award for this reply. Instead of a "yellow jersey" or a "star" next to your "BF name" there needs to be something else. Perhaps a tiny little rendition of botto's avatar?

I already have a 53/39 ..... If I go to 55/42, how much will I increase my average speed ?

That settles it. I'm getting a triple 34-39-53. Should be good for 2 mph average.

55/44 ftw

Only because that's what I had for the tandem and my 53x39s wore out (two sets).

I bought two sets of 53x39s but haven't installed them yet.

But for now I'm having fun rolling the 55 on the descents. Pulling hard down a hill in a 55x11 is fun.

A 50T won't hurt you until everyone is in a 53x11, then you'll be a bit outgeared. I think big gears belong on the bike; on some straights in crits in CT (even in Cat 3 races, and I'm not talking killer races), we'll be cruising along at 35-38 mph. If you want to move up in that field you'll need to do a couple mph more, so 37-40 mph. If you're limited to a 50x12, you'll be over spinning. 50x11, okay, but at no advantage to anyone else. 53x11, now you're one of the bigger geared riders. 54x11 or 55x11? Now you're moving up at a lower cadence than anyone around you. You'll have more gas left in the finale, and if you're moving up when everyone's going 35-38 mph, you're planning on being around for the finale.

Question is why handicap yourself? You can always roll a 53x12 or 13. There's always the option of shifting down, especially in Florida. But if you have a 50T, you automatically chop off the top end of your gearing options.

On the other hand I led out and won a (third group) sprint in a 39x11, in a flat crit, in light wind. So it goes all ways.

Can you pedal 180 RPM?
