Does it make sense to own both compact and standard cranksets?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Does it make sense to own both compact and standard cranksets?

Hi all,

I recently replaced my old Dura Ace FC 7800 53/39T crankset with a new Ultegra 6800 50/34T compact, because I live in a hilly area, and I needed easier gearing to climb better.

Now, I was thinking of selling my old crankset on Ebay, but now I'm hesistant. I might move to a flatter area in a couple of years, so I thought the 53/39 might be useful again?

Does it make sense to own different cranksets for one bike? Is a standard crankset even a good gearing choice for recreational cyclists of moderate ability, even on flats? Or does everyone ride compact on all terrains nowadays anyway?

Thanks!

Is it a problem to keep the old one? You may never use it, but you'll feel better if it's in with your other bike gear and tools. The peace of mind is probably worth more to you than any money you'll get for it.

I'm thinking of replacing my 50/34T with a 46/30T, and with an 11-32 in back, I will lose exactly ONE gear (50x11, since 46x11 = 50x12). Assuming your cassette is similar, unless you use that top gear a lot, you will never miss it.

On the other hand, it is good to keep components for a post-nuclear scenerio, or when you get enough, you can hang them on a new frame.

I would buy a 50t DA 7800 chainring for that crankset if I lived in the flatlands. Actually, I did exactly that a few years ago.

50-39 is a great flatland combo.

If you have two bikes - maybe.
I see no purpose on a single for a 52T+ if you are OK with and 11T rear.
11T - even 12T still make me cringe over chain tension and friction. So I go bigger/bigger.

I might keep it as a spare, but I wouldn't keep it with the notion that my terrain and/or ability might make it preferable in the near future. If you think that a 53-11/12 might come in handy on the flats, go find a flat stretch and wind it up with what you have. I have a feeling that 50-12 isn't going to hold you back. FWIW, I think that many riders would find the taller top-end gearing more handy on downhill stretches than on flat ground.

A 50/39 crankset works great for me living in the flatlands. A 34t chainring was useless.

I've kept my 53-39 in case I decide to use it on another bike some time, or I break my crank or something. Mine isn't Dura Ace though, so the more reasonable alternative would be to throw it away.

I don't think that a standard crankset is a bad gearing choice for recreational cyclists of moderate ability. I'm fine with it, but like you I wanted to spin up the hills a little easier.

Another option is a triple. My Athena-11 has a 52 large ring and a 30T small ring.

I've kept mine, but I also have multiple bikes. I'm not a big fan of compacts, so when I know I'm going to ride where there is going to be some challenging climbs, I'll swap cranks and cassettes. It's nice to have an arsenal of weapons.

Cheers

Seems a whole lot easier to just own a triple...

It would be, as long as you want to use old shifters.

Yes, you have a point that triples are not as easy as they used to be. We now need to swallow our pride and run lower levels of components if we want to 'have it all.' And I'm being serious. Even for myself, who swears by the triple, went with a compact for my latest build because I really wanted Campy Chorus. I'll probably regret the choice but there it is.

If you don't see yourself using it again sell it. It's not going to go up in value.

Yeah, I don't see swapping cranksets for particular rides as something likely to happen, unless you're really riding extremely different areas. I say sell it off and just get another wheelset with a different cassette layout. It's much handier having a spare wheelset than a spare crank, particularly if you don't already have a spare wheelset.

As for riding compact cranks, I hate 'em. I have a 50/34 on my gravel bike mated to a 12-29t cassette, and while it's most fine, especially on dirt, I just don't like the feel of the 50t big ring on the pavement, and regularly find myself looking an 11t cog.

On the road bikes, I run 53/39t and 11-25t or 11-28t cassettes, depending on wheelset, which feel very much better to me, more natural and a better gear spread for my needs.

I'm a fairly fit, long-legged clyde who rides rolling terrain, but perhaps my aversion to spinning triple digit RPMs for extended periods is part of why I dislike compact cranks for road work.

That's not a bad idea in theory, but 7800 cranksets usually sell for $50-$100 on eBay.

$100 doesn't buy much of a wheelset.

Yeah, point taken, and I don't know if spending a few hundred bucks for a second wheelset would be a big deal for the OP or not, but nonetheless, for most riders it is more handy to have a spare wheelset!

You may choose to keep your original groupset more or less intact.

I ride with a "Standard" most of the time, but there was one hill climb ride last year that just tore me up, so I'm planning on on adjusting my gearing for that ride if I repeat it this year. But, after the ride, the gearing is likely to go back to "standard".

Yes. yes it does. I used to keep both depending on where I was riding. Around here - flat and use a 53/39. Going to climb up in Wisconsin - compact.

Swap the crank, lower the front derail and I kept 2 chains - 1 for each setup. Couple of minutes and your in the car headed North to ride some decent terrain.
