Brompton Eazy Wheel bung assembly complete

This kit from Brompton is supplied with the rubber bung which fits into the bottom of the steel seat pillars.

The black bung is for use with steel and titanium seat pillars.

The kit used to contain a grey bung for use on aluminium seat pillars - this is (since 2012) no longer available.

The easiest way to fit the rubber bung to the seat pillar is to have the bicycle folded, lying on its side, or inverted.

Before fitting the correct rubber bung assembly, check that the cone is just nipped up to the rubber bung but not starting to bulge the rubber. In this condition the rubber bung assembly should slide into the seat pillar up to the shoulder.

Note the rubber bung may be a tighter fit in titanium seat pillars and may require twisting to get it in up to the shoulder.

To secure the rubber bung, tighten the bolt with a 5mm allen key approximately 10 turns. The objective is to achieve a good tight fit without excessive bulging that could interfere with the folding operation

Tools required: 5mm allen key

Brompton part number: QEZWBUNGA
