BS20 Bulkhead steerer

The Jefa BS20 type bulkhead steerer incorporates a high efficiency 25 mm ball bearing, which is double sealed and pre-lubricated for a long and maintenance free life. Due to this single bearing arrangement (for compact dimensions) the BS20 steerer should always be used in conjunction with the BS-SUP support bearing. The lip seal at the front is the especially developed Jefa PUR seal, which contains no metal parts for a life long problem free usage. The stainless steel steering shaft has a diameter of 25 mm to guarantee a stiff and strong steering arrangement for wheels up until 1500 mm diameter, above 1500 mm wheel diameter the BS30 should be used. The large internal brake disk provides an efficient and strong braking arrangement. The number of turns achieved with the various sprockets can be found in our sprocket table.
Brake spinner is not included and should be ordered separately.
