I need to pay closer attention to what I'm doing.
Got new rear tire installed, new chain, new sprockets... put piece of wood through rear spokes to hold chain in place while tightening front sprocket. Start tightening, hear loud hiss. Wood had knocked the valve stem out.
Back to the shop to get valve stem replaced.
