I rode to DISC (from the train station) for the Come N Try Day on Sat 11th November ... and there were plenty of people to help take pedals off, and put pedals on the track bikes, etc.
They also helped change the seat height for the track bike. Note that to get to the middle of the DISC velodrome, you have to carry your bike down and then up some stairs - which I found rather difficult on my hybrid
(My road bike is much easier to carry up/down stairs ... giving much amusement to Dave and Kathy the first time I visited them after getting my road bike: "I can carry my bike up the stairs now!" (heaps of laughter from them!) )
