The tilt of your bike seat is really important if you want to maintain and be comfortable in your “A” riding position, see Chi Riding Tip One – Riding Position. Having the correct tilt will mean avoiding genital compression/numbness which we have talked through in Bike Seat “Sweet Spot”.
How to change your seat tilt: You will need a level or a long handled broom and an allen key. The first thing you need to establish is where your seat is currently at, whether you have a neutral, perfectly horizontal seat, or a front or back tilt. To do this you need to place a level or one end of the broom handle on the seat. If the bubble in the level is not sitting between the lines you have a tilt. If you are using a broom the far end of the broom handle will be pointing slightly towards the floor, the ceiling or it will be neutral, see photos below. Please make sure that your bike is on perfectly flat ground e.g concrete in your garage or the living room floor! Some women find a slight, 2 to 3 degree, front tilt helps with genital soft tissue pressure (see Bike Seat “Sweet Spot” for more information).
So if you have decided to make an adjustment you will need to loosen the clamp or clip holding your seat in place. This can be a bit fiddly so just go slowly and be patient. Allow yourself some time…
Your seat is fixed to the seat post by either;
- clamp and allen screw so you will need an allen key to loosen it, see photo
- clip and double bolt so a wrench is needed
Righty tighty, lefty loosey applies to both these tools. Once you have loosened the clamp or clip, make your adjustment to your seat and tighten it all back up. If you like check the new tilt with the level or broom. I find the best test is to get on your bike and see what it feels like.
