Steer tube too short

Options:

1) New fork - $100
2) Go from 15deg 90mm to 40deg 110mm stem - $22
3) Steer tube extender - $30

Trying to decide which route to go.

You forgot:

4) get frame with longer head tube, to be done in concert with #1. $99-5500

I'd probably just get the goofy high-rise stem.

What kinda fork you need? Threaded/threadless, steerer diameter, wheel size, brake type?

Frame is great. Just need the bar height to come up a bit.

It's a Surly Steamroller fork, 1 1/8 threadless.

If I was gonna keep bike for 5 years + then I'd probably splurge for fork. Maybe do a long term WTT for uncut fork on Craigslist. Repost for years, 'til someone needs your steerer length.

Not sure how long I'll hang on to this one. I'll surf ebay and craigslist, though.

I was looking at the BHP22. By the time I factor in shipping, it's about $36. Not bad, but I can't help but think that maybe I'd be better off just putting that $ toward a fork. Decisions...

I'm a "straight and narrow path" sort of guy. If a higher angle stem will do the trick it's the simplest, most direct solution. Why go to great effort and expense to raise the steerer, just so you can use a stem that undoes that to an extent?

Yeah, I'm still thinking about the stem. I'm unsure how the handling would be different with a higher angle stem/short steerer vs. low angle/high steerer. Would there be a difference?

No. Pure mechanics: if forces are applied in the exact same spot and direction, whatever the shape of the rigid body, the reactions will be the same.

For that matter a goofy high rise stem will only affect looks. Handling will be the same.

The only thing that matters is where the bars end up, not how they got there. A short steerer with an high angle stem is better in terms of rigidity, since there's less to flex above the headset. (but I'm not talking about anything significant).

#2, for sure, for cost and function. I think too much emphasis is placed on stem angle/length/etc. As long as the bars end up where you want them, who cares? Frankly I think a high-rise stem looks better than a bunch of steerer (or an extender) and a low-angle stem; I mean, who are you kidding?

Go ask in the road forum and you'll get a different response: either #1, #4, or HTFU.

I just ordered a 35deg 110mm stem. I'm going to give it a shot and see how it does. Thanks for all the responses!

Stem came in and it works great. The 40 degree rise @ 110mm gives me about 1.7inches of bar height increase from my old stem, while bringing the bars about 5mm closer to me. And it doesn't look too bad either.

I'd say it'd be noticeable if you're talking a lot of rise and a 1" quill stem, for sure.

Definitely use less metal to do the same job more stiffly, that's what I say. That's why threadless is win.
