extralite ultrabottom 56

All these different standards makes confusion and isn't so easy to know which standard is correct for yur bike, so the best way to go is to measure frame headtube bore with the help of a precision caliper :

extralite ultrabottom 51-52

With the correct measure and the help of the follow chart, you should be able to choose the correct headset for your bike. You can also find an high-resolution version of this chart inside product pictures.

Extralite UltraBottom 56 is a semi integrated press fit type headset, the lower part that will fit frames with integrated tapered (1.1/8"-1.1/2") headset. Lower headtube bore must have 56 mm inner diameter.

Headset Equipment :

An high quality angular contact bidirectional stainless steel bearing with double seals
A superlight Al 7075T6 CNC lower cone, easy to install and remove without tools
A superlight Al 7075T6 CNC bearing cup, press fit type

The weight in only 32.3 gr. so a great value for a product that it's also better in quality than stock cheap headsets.

Stainless steel avoid corrosion, and the high quality bearing will assure a precise and smooth action and also a longer life.

Extralite Headsets has a minor stack height than standard ones especially for the upper part of the headset. This is an advantage because :

You can get a lower handlebar riding height with the same steering/control parts, and this is important especially with 29" bicycles.
You can use a fork that has a short cutted headtube.
You can use a fork with a longer travel without modify handlebar riding height (of course steering angle will change a little)

We remember you that's also possible to use standard 1.1/8" forks on frames with tapered headset, with the help of the special Extralite Extrabolt 16 adapter :

With this adapter headset bearing will work directly on and headset tapered lower cone will not be installed.

Extralite UltraBottom 56 is an high quality product Made in Italy
