Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

Have pain only on my right sit bone only. Need advice

I recently bought a used road bike. I just went for my first 10 mile ride two weeks ago without padded shorts (which I have now). Ever since then I have had pain on the inner part of my right sit bone only, I thought it would heal up already. It doesn't hurt when when I sit down on a wooden chair or sofa but if I were to used my index finger and pinpoint the area with a push I feel the full breath of the pain on the bone again. I bought the bike to get back into shape I am overweight at 200 pounds standing at 5 feet 0 Inches not sure if that's a factor. Any advice?

I don't have a tried and true solution. As fietsbob suggested, there seems to be some sort of asymmetry involved which may be a slight let length discrepancy. One thing you could try, which cost nothing is can be done quickly, is angling the nose of the saddle a tiny bit left or right. I do this myself and it helps with comfort.

There are quite a few possible explanations, so I'd start with the simplest which is saddle too narrow. You can find a variety of ways to measure sit bone width (varying in degree of indignity) with a quick Google search. Your saddle needs to be at least a couple cm wider than that so that your sit bones rest squarely on the saddle and you can move around slightly without "falling off" one side or the other. If things check out, then the problem is elsewhere. If not, it's time for one of the most frustrating quests in all of cycling -- shopping for a new saddle.

As to the area still being sore after two weeks, only a qualified medical professional can tell you whether that's "normal" or if some action needs to be taken. Internet medical diagnosis are even less useful than internet bike fittings

I don't know that saddle width is the simplest or most likely culprit; this is, after all, a used bike, so the saddle could be worn unevenly from the previous owner, or there might be a problem with bent rails, or a cracked shell...

I'd first inspect the bike closely and verify the seat seems symmetrical (e.g. not leaning to one side, padding equally dense side to side) and is in proper order (not cracked underneath; rails not bent or seat post clamp touching bottom of saddle). I'd also affirm the saddle is oriented straight ahead, and not angled to one side or the other.

It's also not your weight, though it may be the way you're sitting on the bike for some reason, so just consider what you're doing as you're riding, for example, favoring one leg over the other. It could be a mild scoliosis, or a leg length imbalance, or some other physical condition.

If those things check out, and your reasonably comfortable that something with your body isn't going on, I'd go ahead and start playing with saddle selection. If you can't get comfy on the one you have now, it may be that you're sitting on it oddly trying to make it feel better.
