Reaming a 28.6 OD seat tube for a 27.2 ID seatpost is no big deal. 27.2 is by far the most common and frequent seatpost size for all 28.6 OD steel frames and been that way since I can remember, at least the early 80's. It's not going to compromise anything or put the rider or the frame in any danger. My '83 Stumpjumper took a 26.0 post, talk about overkill, as it was a straight gauge tubing tank of a frame.
If I bought a frame from Rive that wasn't to spec the first thing I'd do is call them. It's neither normal or acceptable. These things are supposed to be taken care of at the time of the frame build, but it's also Riv's responsibility to see that the shop is doing their job as contracted. Since Riv is point of contact with the buyer, it's up to them to make it right. That every frame is not checked is unbelievable, especially considering the cost of the frames. Even most local bike shops will do that as part of basic complimentary frame prep on new frames sold if requested. I had a BB issue with my custom Franklin in 1999 for which the builder offered to send me his BB threading tool since I didn't have one. While I opted to take it to a shop in Pittsburgh that I could do it myself at, I surely appreciated the gesture. Kalloy posts are really cheap. They don't use very beefy bolts either. They could make the radius style post Riv often includes to be a whole lot more slip resistant if the top of the post upon which the clamp sanwich rests was bead blasted rather than slick. I have two vintage single bolt Campy seatposts from the 80's. The Nuovo Record(NR) has the top of the post bead blasted, the Super Record(SR) is polished. Guess which one slips, and which one doesn't. NR for the win ! There's supposedly friction pastes around for carbon fiber, but I don't know if they're applicable to aluminum or not. If they are, I'd surely try some under the clamp sandwich, on the top part of the post upon which it rests. Then it can't rotate so easy. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
