Tire Changing

You can drop by any time during working hours to change your tires, but there will not be any assistance unless you have made specific arrangements with someone.  The following people have access to the tire changer on evenings and weekends and may be able to assist you then:

Earle Bare (610) 524-9336 (w) (email)


The tire changer is communal property of the group.  $40 gets you unlimited use of the tire changer for your tires, or you can pay $5 per tire until you reach $40.  In addition, there is a $5 fee per tire, regardless of whether you are fully paid-in or not, to cover disposal and consumable items.  Excess funds will go towards purchase of additional tools.

Pay the $40 or $5 to Earle or leave it in the book..
Drop the disposal fee into the donations can.

If you are going to change tires, use the ramp in the back parking lot (if the door is opened for you) and pull all the way through to the bike room. There is plenty of space in the warehouse to remove the wheels.
