Had the bike in for 10k maintenance. Tech found a "surface crack" on the lower right frame.His advice was to lower rear tire pressure and check frame before each ride? Anyone ever heard this before? Seems like lower pressure might affect handling.

Lower tire pressure will probably reduce stress on a hardtail frame but you need to address the real problem of the surface crack. That was poor advice!

What is a "surface" crack? The paint only, the top part of the frame tube? How deep does it go?

If it were my bike I'd sand down the crack and see what's up. If it is in the frame I'd get it welded a/s/a/p and paint over the weld.

I ran mine at 40psi for months, had a new rear tire fitted and my mate who owns the bike shop said he didn't know what pressure i was running it at so he set it at 22psi, when i told him what the recommended pressure was he couldn't believe it for a rigid. I rode it home and it was like i was riding a soft tail, have been running it at 26psi for the last 500 miles and cant believe what a difference it has made and it handles no different to what it did before. Still shit. lol

Yeah, checked tire pressure awhile back, it was at 30 and I went WTF?? filled it to 40 psi, went for a ride and it vibrated like a massage chair...came back, let the air back down to 30psi and no more vibrations....:2thumbs:

The guy has no clue on what is involved with a cracking of metal obviously. He should be looking for ways to fix the crack rather than telling you to lower the tire pressure.
If you can clearly see a crack in the frame, you need to get it fixed by a metal fabrication shop. One that has repaired frames and knows how to TIG weld. If you were closer I would help you out. Just did 2 American Ironhorses last month with cracked swingarms.
Good luck!!

Andrew is correct! Lowering the tire pressure may make the ride FEEL smoother, still doesn't take the PRESSURE off the frame...have it fixed correctly!

2X Telling you to lower the pressure is like saying turn up the radio when your motor is making noise from being out of oil.
