I bought a Cube Attain GTRC disc, a great bike apart from the saddle, which is quite chunky and square.

I would like to find a better one. Tips for saddle sizing for road biking?

  • Long saddle versus short
  • Cut out or not
  • thin versus thick
  • measurement of sit bones? how?
  • material?
  • brands?
  • length of ride

I once went to the cycle show and sat on a special seat that displaced blue gel and showed the shape of my arse. Is this recommended? Not sure if I will find these in IKEA though.

    you become a prolific buyer and seller of saddles on ebay burning through £1000's in the search of the 'right' saddle. Finally, just when all hope is lost, you find one that is perfect - unfortunately, it is also discontinued, so next time you need a saddle you will need to start the whole process all over again.

  • @AndyP - when you find just the right one and discovered it's been discontinued, you continue your scouring of all known sources to buy a 2nd one right away!!!

It is very much like with shoes: very personal. You look for one until you find it and then you use the same model for as long as possible.

Or, one can use service of a tailor, or in this case, bike fit expert, for a price. Sit bones measurement is one of the most affordable things, as a simple cardboard can be used for that.


For complex cases, a custom saddle can be molded specially for you. See an article by Lennard Zinn at VeloNews.
