This month we are going to look at saddles.  Saddles are great when they don't move while you are using them.  If the saddle moves, it may throw off your balance and make riding a challenge. Even worse, you could get hurt trying to complete a trick you have been working on.  There are two different styles of hardware that hold the saddle to the seatpost. The first style is a 10mm - 1.5 acorn nut.  The most common and still widely used should be kept snug.  If you have a torque wrench handy it will be 10 ft-lbs/13.6 N-m. The second style is a 4mm or 5mm M5 button head.  This is used in the new KH saddle base, you want to keep this tight as well.  If you have a torque wrench handy it will be 8 ft-lbs/10.8 N-m.
