After experiencing a particularly bad ride last week, I noticed my seat post had slipped down and was some three inches lower then it normally is. I adjusted and had a great ride the next time out.

About half way through Fridays ride, I noticed when worked the pedals a with a little more speed I tended to get wobbly, my arms started to hurt, so after I got off the bike it was noticeable that the seat was much lower then it was when we started. The seat was FINE before we started and I hit not a single bump or anything, nor did I notice the seat actually go down so it must have been a gradual slip. I took the bike into the LBS today and they cleaned and re-lubed the post with a lubricant with a bit of abrasive in it. The quick release was as tight as I could manage to get it, but he said he tighten it as well, so I HOPE this fixes things.

While I was there, I did mention the rear break and it seemed a little mushy and perhaps needed adjusting, the tech said he did notice some rubbing and was about to check it out. Then I notice them (slow day at the bike shop.. you walk in and within five minutes two techs are working on your bike, but makes one feel good) taking both the front and rear tires completely off the bike and over to the truing stand and I can SEE that as he spins the wheel the tire is out of true. I ask if it's indeed out of true and says yes, just a bit.

Now I have only 25 miles on this bike and perhaps another 20-25 miles on it while in the trainer, but I really HOPE this isn't something to worry about. Now I know I'm a larger gal and am 200+ pounds, but this is a cruiser bike with 26", 32 spoke wheels, so this is just befuddling me. Is this "normal" for a new bike to have a period of settling in and adjustment like this or is this due to flimsy, shotty wheels for a larger rider?
