Remove your old saddle Undo your old saddle using either the allen key or the spanner.  There are all sorts of different seat clamp designs.  But all YOU are looking for is screws or bolts (see photos).  Lefty loosey – turn the screw/bolt to the left.  The screws or bolt will need to be really loose to allow the saddle railings to slide out of the clamp.

Attach the new saddle: Put the new saddle railings between the clamps and begin to tighten the screws or bolt back up.  Righty tighty – turn the screw/bolt to the right. Before you tighten the clamp completely onto the rails read the points below.  Expect to have to do a bit of fiddling here to get the saddle in YOUR “sweet spot”.

Find the correct position for your saddle: You can adjust your saddle to get a position on the bike that works best for you. Please note this will not be instant and will come from minor adjustments that you do following the feedback you get when you ride.

The 2 adjustments that can be made when attaching your saddle are

Reach – the railings can slide in the clamp effecting how far away the seat is from the handlebars.  If you look at your seat rails they will have markings.  Try not to clamp the rails outside of these markings.

Tilt – the tilt is important if you have been experiencing genital numbness/pain.  A lot of women prefer to ride with a 2 to 3 degree front tilt (nose of saddle pointing slightly down)
