Is your wheel dished?

Yes. And yes. The wheel slammed perfect on a 13.75 backend running a 27-9 ratio. I normally don’t even buy a frame unless I can slam the backend. Now with this frame and 3mm simple spacers and a 25-9, the wheel won’t sit straight. Even without the spacers the wheel pulls extremely hard to the right when I tighten it down. Never seen this on an aftermarket frame 17 years of riding. And believe me I’m a nerd about bike stuff.

I think you meant to say your wheel ISN'T dished homie ;>

Pop it in a truing stand and check

The reason it does it with or without the slammers is that the hub is squaring itself up with the dropout. The only reason I inquired about them was to make sure they weren't inside the dropouts, causing the OLD to be too wide for the dropouts to be parallel. A 14mm axle in this case would typically actually bow in order to have the locknuts (instead of the wheel itself) square up (coning-out the bearing seats over time and causing hub wobble), but you are running a 17mm

I've seen plenty of frames (including $$$ custom jobs) do this and don't doubt that the frame could be to blame, I am just trying to help you diagnose it

BTW, just for your and others' information, "13.75" is just there for somewhat roundness and/or compliance with completely-wrong gear charts and the like (including Bg's), it would have been 13.6" in reality. It's a silly convention that has caught people out in the past (like jonathon) when you get a frame that actually IS 13.75" and your 13.6"-slamming gear ratio and chain length is suddenly too short :<

Patty:
I’ll stick to my screenshot of Fit’s chain length guide (put together by leading industry experts!) that has served me with perfectly slammed backends with outstanding chain tension with my last 6 or 7 frames. But thank you for your expert opinions professor! I’m glad my posts prompted you to insert your backend knowledge on a dying forum.

Do share your screenshot
