Seatpost question
 

I bought an older Orbea frame that came with this seatpost. Have realized that the diameter is 27.2mm. Is this a standard diameter for a seatpost? Will I have troubles finding replacement seatposts?

27.2mm is one of the closest things to what could be called "standard." Seatpost sizes are also reasonably well-supported in the replacement parts world.

+1,

While there's no standard 27.2mm is far and away the most common diameter used on mid level and better bikes. 27.2 probably accounts for over half the replacement posts sold, with all other sizes sharing the other half. I don't know of any high end post that is not offered in 27.2mm.
