What are the advantages and disadvantages of compact frames for road bikes?

Answer 1

In my opinion, there are lots of advantages, and few, if any, disadvantages in a compact road frame.

First off, you have more stand-over, so if you do have to step off your bike in a hurry, you run a slightly smaller chance of landing on the top tube. Secondly, they're lighter. Not by any large amount (we're talking grams here), since your seat post has to make up for connecting to a smaller frame, but there typically is a very small weight reduction. Thirdly, they're stiffer, since all the tubes are shorter per a given size frame, which offers better acceleration and overall performance.

Anyhow, there's my two cents.

Answer 2

I think everyone else has summarized things pretty well - weight, rigidness, gearing.

The one thing I would add is purely personal preference. I think the 'traditional' frame looks better then the compact frames. Maybe I am just too old, or saving those few grams of weight on the frame really doesn't matter (expecially when you consider that I could stand to lose at least 20 lbs off my own 'frame').

BTW - I own a compact frame. I want my next bike to be traditional design and Steel !!!

Answer 3

Well, the above posters have the advantages down pretty good, no need to rehash.

Disadvantages: If you're a bit on the big sie for a particular frame, you can't get the handlebars up very high. Not an issue if you can do the low, aero position well or are used to it. If you aren't it could ceretainly be an issue. The other disadvantage I see is that it's not as "compliant" and will transmit every bump and jar with authority. BUt the biggest thing is, it might not fit your proportions a well - these are built for "typical" riders, and if you're non-typical (for example, short torso and long legs) it may not fit as well.

I'd say ride one for a while and see what you think before purchase.

Answer 4

ive ridden both and own both.

compact frames are lighter, but you actually add weight by puting on a longer seat post (a seatpost weighs more than a custom butted frame tube)since the triangle is smaller, they tend to be stiffer, which makes it better for climbing. I prefer the compact frames because i feel safer and lower on them eventhough im really not, but im a strong climber so that benefits me.

traditional frames feel more comfy to me (given the material is the same). I do like the appearance of trad. frames; they look more aggressive, as for compacts look like mountian bike frames with road components. when i sprint, i tend to throw the bike around under me a lot and a traditional frame top tube tends to hit my legs, but the compacts feel more flickable (like a bmx bike being so small). I can also track stand a compact better (Maybe lower center of gravity).

Answer 5

Advantages - if you are a small framed person, this allows a more aerodynamic tuck for time trials and and long flats on aerobars.

Disadvantages - big frames person has problems, plus less room to open chest area for breathing.

Answer 6

Advantages: lighter weight, easier climbing (with compact gears).

Disadvantage: need to pick better gear ratio because harder to go fast on flats or downhill.
