BDop Da ROUGHSTUFF HEADSET
 
The BDop Da ROUGHSTUFF HEADSETS are designed to add a little security when things get rough.
Along with the bolts on your stem, the lockring hidden away under the top cap helps keep your headset from coming loose when the going gets a little tough.
It also allows you to completely remove your stem and bars to service your bike or to pack it in a box or travel case while only having two hands.
Da ROUGHSTUFF 1 1/4
IS42/28.6 - IS47/33
The Da ROUGHSTUFF headset is unique in that is has an additional locking mechanism built into the upper race for added security.
This also means that the clamping forces on the fork steerer tube are spread over a wider area because it uses an additional bolt within the headset and not just the clamping bolts on your stem.
The Da ROUGHSTUFF 1 1/4 headset is designed for tapered headsets that have 1 1/8" upper and 1 1/4" lower races.
The Da ROUGHSTUFF 1 1/4 headset can be purchased with either a top cap and star fangled nut which is suitable for alloy steerers or a compression nut that is suitable for forks with carbon steerer tubes.
The Da ROUGHSTUFF 1 1/4 uses Sealed ANGULAR CONTACT BEARINGS.
Angular Contact bearings are better for headsets because they distribute both radial and axial loads evenly prolonging bearing life.

Headset Specs Explained
With a proliferation of headset specs in the last few years it has become increasingly difficult to determine which headset will fit in which frame. Hopefully explaining the jargon used to identify headsets will help make it easier to get the headset you need.
This is an example of a code used to describe a particular headset.
The first group of numbers (to the left of the vertical line) describe the upper part of the headset while the second group of numbers (to the right of the vertical line) describe the part of the headset that will fit into the bottom of the head tube.
The first letters 'EC' refer to the type of headset being described and is explained above.
The second set of numbers ' 34' refers to the size of the hole in the top of your head tube where the headset cups or bearings will go.
The second number "28.6" refers to the diameter of the fork where you will clamp the stem. Most contemporary bikes use the '28.6' size which is a 1 1/8" fork.
The vertical line seperates the upper and lower parts of the headset.
The first letters 'EC' refer to the type of headset being described and is explained above.
The second set of numbers "34" refers to the size of the hole in the bottom of your head tube where the headset cups or bearings will go.
The '30' refers to the size of the crown race that will fit on the steerer tube of the fork that will be installed with the frame.
We hope that makes selecting the correct headset for your frame a little easier. If you are still unsure of what you need please contact us at our sales email and hopefully we can sort things out for you.
