Okay, my bike (52cm in orange) is supposed to show up tomorrow so here are my noobie questions....

-I'm definitely going to want swtich to a 18t cog...could someone please point me what I should order? There seem to several different varieties. And which spanner tool do I need to remove the locking...I've already got the chain whip.

-I'm going to want to switch the front wheel to quick release to make transporting the bike easier on the roof rack. Does anyone sell a hollow front axle that would fit?

Thanks,

Roland
