[RBW] Re: Sam Frame Spacing
Another original Sam owner here. Something you might consider if you have a frame builder nearby is to have your frame put on a jig and have the rear alignment checked/adjusted. That's the beauty of a steel frame. Phil, running 42s and fenders On Monday, December 19, 2016 at 3:42:13 PM UTC-7, Timothy Hurley wrote: > > It's a 58.

[RBW] Re: Sam Frame Spacing
Bill, thank you for taking the time to give such detailed advice. What you said makes sense. I measured everything, flipped the wheel and measured again. Everything was the same both times. So I've established the wheel (it's true) is dished corrrctly and thus not the problem. The wheel was correctly seated in the dropouts both times. Everything was centered at the seat stays both times. And both times the wheel was almost touching the right chain stay yet had plenty of room on the left side. The only thing I can figure is that there's an issue with the frame. Everything looks straight and I've never crashed it anyhow. This bike has searved me very well over the years and rides great so it's really only a problem if I wanted to put 40mm or up tires on it. I was happy with 35's until I discovered this group last year! Haha Thank you again for helping me obsess about my bike. -T.J. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Sam Frame Spacing
Timothy Step 0: your rear wheel is true Step 1: with the bike on the ground, open the QR so you are sure the frame is fully dropped down on the vertical dropouts. Close the QR Step 2: measure clearances at all four points: both sides at the chainstays and both sides at the seatstays, write those down Step 3: remove the rear wheel and put it back in backwards, making super sure that the wheel is fully in the dropouts again. close the QR Step 4: make the same four measurements If you don't have a good way to do measurements, fine, eyeball it. IF your wheel is exactly centered relative to the seatstays both times, then the wheel is dished correctly. IF the wheel is centered exactly relative to the seatstays both times and is offcenter towards the right chainstay both times, then your rear end has an imperfection of some kind. IF your wheel position changed both at the chainstays and at the seatstays when you flipped it around, then your wheel is not perfectly dished. Consider taking care of that and repeating. The amount it moved is double the amount your wheel is out of dish. For example, if your wheel is 2mm out of dish, it'll "move" 4mm when you flip it. IF your wheel changed in position at the chainstays but not at the seatstays, or vice versa then you are not being careful enough when you are getting the wheel seated in the dropouts. Repeat until you are getting consistent results. Let me know if you need help walking through this.

[RBW] Re: Sam Frame Spacing
It's real easy to check dish..I made a tool out of cardboard and a small ruler. have you tried loosening/re-centering? PS: I also have a green Sam w cantis and people ask me what year that is - what is 'first year' and a photo? Thanks!!
