Diatech Steuersätze von [[Dia Compe]] haben ein sepzielles Paar Manschetten. Die eine Manschetten wird unterhalb des Vorbaus und die andere direkt über der oberen Lagerschale montiert. Die untere Manschette hat eine angeschrägt konische Oberseite, die in die innere Anschrägung der oberen Manschette passt. | |||
Die obere Manschette hat einen kleinen Spalt an einer Stelle. Dieser wird mit einer Schraube zuzsammengepresst. (Bei manchen Steuersätzen kann man hier noch einen [[Zuganschlag]] für die Vorderradbremse montieren, wenn das Fahrrad eine [[Starrgabel]] und konventionelle [[Mittelzugbremse]]n hat.) | |||
Der Vorbau wird sehr fest am [[Gabelschaft]] festgeschraubt, so dass die obere Manschette nicht anch oben rutschen kann. Durch die Kompression der oberen Manschette durch die Schraubklemmung wird die untere Manschette nach unten gedrückt und verhindert so Spiel in den Steuersatzlagern. | |||

The YST "GeForce" headset, unfortunately no longer made, has a collar which slips over the steerer, clamped to it with a binder bolt. The outside of this collar is threaded, and the upper bearing race screws onto these threads. The assembly is fitted with a binder bolt that clamps it tight onto these threads when the desired adjustment has been attained.<br><br>The GeForce is the only threadless headset which doesn't use the handlebar stem as part of the adjustment. This headset could be used with any stem, either external clamping or internal expander/wedge type. It is commonly found on Bike Friday folding bicycles made in the mid-1990s.<br><br>To adjust a GeForce headset, loosen the binder bolts in the collar and the top race; screw the collar and upper bearing race together, then back off by a fraction of a turn. Tighten the binder bolt of the collar while pressing the assembly down; turn the top race to adjust it; then tighten the binder bolt of the top race. The collar uses a 4 mm Allen wrench, and the top race, a 2.5 mm Allen wrench -- available at some bike shops and at better hardware and auto parts stores. You might take the collar/upper bearing race assembly with you to check the fit of this wrench when you buy it. | The YST "GeForce" headset, unfortunately no longer made, has a collar which slips over the steerer, clamped to it with a binder bolt.
