What techniques or gear can I use to help with butt fatigue after an hour or more in the seat? I want to work up to a 300 mile trip, but currently have to stop and stretch after the first hour and the second hour is uncomfortable. I love my Sun X-frame, but don't know how to cope with the sore-butt issue during longer rides. I'm riding 2-3 times per week.
Thanks
Jim

Jim,

Lean the seat back more. An extremely upright seat is the source of butt pain.

warren, Is it true that the more recline you have in the seat, the closer the seat bottom needs to be to the crank?

That depends on the seat. It's more true for Euro style hardshell seats than the Sun seats where the back moves independently from the base.

A RANS seat on a Tailwind. It is all in one piece.

Yeah, seat pan tilts up as seat tilts back, so you may need to adjust the seat a bit forward when you tilt it back.

My problem is tailbone pain. I broke it once. I have my seat all the way back now, and will try it tomorrow. I move it back the only notch left today, and moved my seat about 1/4 inch forward. Any other ideas on my tailbone pain elimination project. Thanks for you comments.

I've been using Confor foam pads on my trike. Depending on temperature, I use either soft (winter) or medium (summer). The foam used to be called Temperfoam and is the stuff used by NASA for astronaut seat pads. You can google search the stuff, there are several suppliers. I got 1" thick pads (16 x 18") 1 soft and 1 medium and cut them in half so I have 4 9"x16" pads. I use one pad on my trike. When it's cold I use the soft one and when warm-hot, I use the medium one as the stuff gets stiff when cold. It's the same family of viscoelastic foams as the memory foam mattresses. You might try cutting a U in the foam so the contact with your coccyx is eliminated, while still supporting the glutes. You could also carve some foam away from the foam pad in your RANS seat.

For anyone who cares, I solved my butt pain problem by getting a lumbar support made of foam, stuffed it down between the back of the seat and the seat back, leaned my seatback all the way back, got my seat distance right after several adjustments, and now I have a dream ride.

I talked too fast. I rode 20 miles this morning, and my butt and lower back are killing me. I can not figure out what I can do to carrect the problem. Very frustrating.

I know that I live in the UK and that seeing a doctor here is free (apart from what we pay the NHS via Tax) but have you seen a medical professional about this problem. I am not trying to be rude but the problem may not be with the equipment but may be showing up a medical problem you have that has not been diagnoised previously.

Hope you manage to get this sorted soon.

Have you tried sticking another layer of foam under your butt? Maybe that will get your coccyx above the metal tube.

The is the RANS seat that has the bottom cushion in a "PAN" rather than on a flat surface. The problem is the back lip of the "PAN" cuts into my butt when I am sitting because the foam compresses down past the lip. I have just inserted an old gel cushion off an old DF bike under the RANS cushion, and extended it over the lip in the back. It's kind of strange feeling, but it might work. I also put the lumbar support I bought in between the front and back mesh panels on the lower back of the seat. I'll take her out for a spin in the morning and see what I've got. I bought a recumbent for comfort, and so far it has been a battle to find it.

Also, since the bike is 11 years old, I probably need to order a new RANS seat pad. That foam probably deteriorates over the years, you think?

Yes, it probably has been crushed down, You could always just try some cheap foam for a test.

There's a "fix" for the old style RANS pan that entails running a reinforcement strap across the bottom near the back and cutting a crescent from the pan almost to the inside top surface of the bottom of the pan. The Stealth way is to rivet the strap inside the pan, the slightly stronger way is to rivet the strap to the outside of the pan. I'm told that either way works fine as long as the strap sits flush to the pan. Use a 1"*.065 steel strap that covers the area from either side of the seat mount.

My gas is up to $0.99 a burrito, $5.99 for premium and I'm only getting 10 miles to the regular burrito. Dang $0.99 burritos are smaller now.

Thanks, but that is way too complicated for a novice like me. I am trying to learn to just slide my butt a little forward on the seat, rather than all the way back. Seems to be working for two rides so far. I have no idea why I have such a tendency to want to push up against the lower back of my seat. Weird.
