Is there a big dif between a 1" vs 1 1/8" steertube?(13 posts)

Is there a big dif between a 1" vs 1 1/8" steertube?Jackyo

I am deciding on which frame to get, the older model has a 1" steertube opening while the newer one has a 1 1/8" but the newer one cost more. I am trying to save some money and get the old model. is it worth the extra $800 to get a 1 1/8" steertube opening?

If that's truly the only difference between the two frames... no, it's not worth it. There is no discernible difference between the two sizes, it's just that as 1 1/8" becomes the de facto standard it is getting more difficult to get 1" steerer forks. There are still plenty available now though.
I'd say it depends.nee Spoke Wrench

What's the rest of the bike? If you have no budget restrictions, a 1 1/8" bike will allow you to use a significantly lighter fork that has a carbon steer tube.

Other than that, it looks to me like the consensus of the board is the advantages of 1 1/8" are marginal at best. If money is limited, you might not be able to afford the carbon steer tube fork anyway. $800 will sure pay for a lot of upgrades in other areas of the bike.

yes 1 1/8 yields 26% stiffer steer and there're animals who can really crank out omps and flex the hell out of it but the truth is for most it won't matter. Think until 1 1/8 came out what did all pros ride?

I would suggest to exercise caution if
- some fork/frames are known to be flexy
- you're a big heavy and powerful rider
- you're very strong and have weight lifting background.

Other then that spend your money on something else more useful like a set of rollers and TdF tapes good luck

For that much of a price difference I'm suprised the headtube dia is the only difference. What year models are you looking at? What is the frame? I'm with the other guys, I just recently bought a new frame with a 1-1/8" headtube and don't really notice that much difference from my old 1" frame. I also agree that fork availability is not quite as much but it's not really an issue. You can get a Look carbon fiber fork in a 1" steerer that is full carbon. I think they are the only ones that do that except for maybe Cologno (sp)... but those forks are 700.00 yea-ow.

Ouzo Pros (carbon steerer) are also available in 1"

Cheaper tooling costs for manufacturers that make both road and mountain bikes.

... and kiss your Chong goodbye...

It might be a while coming... but if this 1.5 standard takes off for MTB's... it'll probably spill over to roadbikes for the reasons you mentioned...

We abide.

This is aimed at the downhill crowd. Even the proponents state this. It has a pretty specific purpose. The MTB crowd is not ready/willing to buy into this for XC riding or racing. It's not hype and marketing but has a fairly limited application.
Probably depends on the rest of the frame.nee Spoke Wrench

As I understand it, the original idea behind the 1 1/8" headsets was to simplify frame building. If you have a big, fat down tube and a skinny head tube, the mitering at that joint gets tricky. One of the easiest solutions is to use a bigger head tube.

... while 1.5 is aimed at the suspension specific downhill crowd... so too was 1 1/8 inch (at one time)...

As market shares become tighter and tighter... and marketing gurus try (in vain) to predict new trends (MTB, Road, 'Bent, ... next big thing) you'll still probably see more "standardizations" to cut production costs and boost the bottom line... if we're not careful... someone will try to reference road bikes by noting their tire size and differentiating them as "mens", "womens" and "kids"...

We abide.

Not $800 worthLewis

1 1/8 is lighter, stronger and makes a prettier head tube. The clamping forces of a stem on 1 1/8 is more even than a 1" so its less likely to damage a carbon steerer.
Choices in 1" maybe limited- but there are plenty out there now.

It's not worth $800. The performance gain is marginal at best. Pros ride and win on 1" even now. Get the cheaper frame.
Big difference? No, there is not.Bernie
