So…what’s the relationship? I assume saddle measurements are from edge to edge?
Anyone know the best way to measure sit bone distance? Went to LBS for the Specialized thingy, but it was beat to hell from overuse.
My unscientific tape measurement was around 155mm…but I’m only 5’8" 150lbs 30" waist. Anyone have recommendations?
Wait a minute, someone told you they could measure your rear and pick you a seat? This was not for a fee I hope.
For the past 15 years the number one seat in the Pro Peloton has been the Flite, and variations there of. Almost ever saddle since then has copied the Flite, and or its design. Tri seats are a whole new beast and have been taken over by Fizik and their design. Profile had a seat with Jello on the front, and some copied that but it was fleeting.
More often than not, you dont have a problem with your seat - you have a problem with your fit and the way your bike, and body carrying our weight as you ride.
You could go out and get a five pound Brooks saddle and break it in and wish you had done it sooner (and ride 36 spoke wheels). NO SHOP with out an Xray can give you a real measurement of your hips, where you sit or how you sit. This harkens back to the days when shoe sales folks had xrays to look at your toes in shoes (while they give you a few rads).
While I am sure that some scientist somewhere could come up with a pad to measure every inch pound of pressure on your ass to see where your sit bones are, this just wont happen at a bike shop any time soon. What you need to do is try seats out. If you race Tri, I suggest a Fizik, or even a Flite (I raced 7im races n a Flite). From there, try a Terry, and any other brand that suits your fancy (and fanny).
What ever you do - dont pay some moap at an LBS to measure your “sit bones” as when you are on your bike - you are not on them like you are eating dinner.
The Specialized Assometer is a good place to start and gives you a decent estimate of what size saddle would be a good one to try first. However, the distance between the sit bones is not the size of the saddle. The Assometer has a scale on top of it that estimates your saddle size. If you did a good job taking your “measurement”, just hold that up to the scale and it’ll give you a decent starting point.
