Single bolt vs double bolt seatposts?
Ere it just my imiganition, or do one-bolt seat posts not "hold" as well as two-bolt ones? On two of my bikes, I've used one-bolt seat posts (one post a Campagnolo brand and the other a Kona brand). After riding for maybe 50 miles or so, the seat tilt seems to have shifted slightly (despite my putting a gorilla move on the post bolt when tightening). Is this common or am I just too fat?
When I use two-bolt seat posts, the seat tilt NEVER shifts, and I can adjust tilt in much finer increments. I understand that the one-bolt models are slightly lighter than the to-bolt models, but this is not a significant issue for me.
I believe my recent run in with seat pain after an hour in the saddle may have been caused by the saddle shifting to a slightly "nose up" position that I hadn't noticed.
In any case, I'm about to switch out both the Campagnolo and Kona one-bolt posts for two-bolt models on my bikes. Hopefully, this will cure my positioning ills.
