Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

threadless setups: headsets, forks, steerers

My fork's steerer is too long, and I'm going to have my LBS cut it down a little.

Is there a "best practice" when it comes to steerer length / spacers on a threadless setup? Aesthetically, it would seem that there shouldn't be a need for any spacers, and if there needed to be a rise for a better fit (from saddle to bars) that the rise could occur via the stem and/or handlebar selection.

Am I incorrect in this assumption?

One potential flaw with cutting the steerer down super short could be that it wouldn't allow for any variation in height of the headset and stem, right? Or are both of these measurements standardized/universal?

I'm currently running risers, and I have put the stem down lower on the steerer, and everything still feels fine, fit-wise.

Thanks!

I like using spacers because you can fine tune the fit easier than if you were to use various stems. Cheaper too. I also leave 1/4" to 1/2" of spacer (with corresponding steerer tube inside) on top of the stem in case I sell the bike. It lets the user further fine tune the bike to their needs.

It's a question fit and riding style. As for fit, some people's proportions dictate that when they ride a stock frame size, their arms are of such a length that they need to have the bars further up, or back, so as not to be stretched out too for forward. Like me, for example- my legs are longer than my arms for a man of my height, so I need to add some spacers to bring the bars up to my T-rex arms.

For riding style, some people like to be more upright versus a more aggressive, racing position. So they also would want more spacers.

if you're leaving more than 4cm of steerer exposed, it's better to use a few large spacers (or just one) rather than a whole stack of tiny ones— they don't shift around as much. some manufacturers recommend putting a spacer above the stem to even out the force from the top cap. never use more than 4cm of spacers on a carbon steer tube unless the mfr. says it's OK.

Ehhh. Wrong. If your spacers are shifting around, then you're not doing it right.

Oh, that two in the wrong column.

Possible redemption, the quoted value is typically 25mm for a 1" steerer, 30-40mm for a 1 1/8" (they remember it as stack height = steerer diameter)

Don't cut for risers. They won't be cool in a year or so any you'll be left with a shorter steerer.

thanks for the advice, everyone. sounds like the best bet is to not trim to the absolute minimum, but leave a little space, just in case.

update: i ended up picking up a pipe cutter for $5.49, two different sheets of metal sandpaper, and a dowel-rod for $1.39 (to take out, then put back in the star nut), and trimmed it down, losing exactly an inch of spacers
