[Closed] Looking for a bit of advice on steerer tube length

Hi folks, I'm after a bit of advice regarding new forks for my Alpine 160. It's a 2010 model so 1 1/8" head tube. Thinking of going from the Fox Float 36 to a set of Marz 55 rc3 ti - about the only 'upgrade' forks that I can still get with that steerer tube!

My existing forks have a 200mm steerer tube, and I run 10mm of spacers under the stem. If I go for a set of forks with a 190mm steerer tube, I'd have to lose the spacers, but the overall height of the bars won't change as the forks themselves are 10mm longer anyway. My question is - as the front of the bike would rise regardless, would it be preferable to keep the angles between saddle, crank & bars the same, or would effectively dropping the bars 10mm make a big difference in handling?

Any advice is much appreciated - cheers! :mrgreen:

The bars might be the same hight from the ground but they'll be 10mm lower relative to the saddle. But the front end will be raised a bit so the bars will angle back to you a fraction. You might notice a difference for the first ride or two, but I'm sure you'd get used to it pretty quickly. I know I would.

As its not that much of a difference you should get used to it after a couple of miles.

The 55RC3 have a short A2c. Mine are 170mm and they replaced some 160mm Fox 36s and my front end is slightly lower. Lovely forks though.

I didn't notice after about 10 mins of riding. But it you're worried the head angle will be a bit steeper then spend £20 on some offset shock mounts from www.offsetbushings.com and that slackens an Alpine 160 by about 1 degree.

If you're happy with 10mm of spacers leave them there. You won't even notice the extra 10mm of travel, slacker head angle, etc, compared to the forks' other characteristics.
