These came from a set of Roval Carbon Control Trail SL 29 wheels with the OS bearings on drive side (non-disc side?) of front hub. (See included images for decal and hub style; no hub, rim or wheel included :). These end caps adapt that front wheel to a 20mm thru axle fork or a QR fork with the Rockshox/Specialized 28mm OS clamping surface. Note, that they are markedly different size to accommodate the asymmetrical bearings in that hub. Also, note that they do not fit the wheels with the confusingly similar name Control Trail Sl 29, which have a smaller front hub and bear a swath of snazzy red spokes.
