Lefty frontwheel wobbling - normal?
I am a new Lefty owner, and I have noticed that the frontwheel is not 100% tight.
When I grab the wheel at the tyre I can rock it slightly left/right, but it isn't that much. Enough though so that I noticed that there is some play when I moved the bike around at home and checked...
When I grab it at the hub there is no noticeable play.
Does that sound like it is within the "normal" specs of a left fork and hub, or should I do something about it?
PS: Yes I have checked if the wheel is properly tightened to the fork.
Does it feel like there's play in the bearings, or are you possibly flexing the wheel?
I had a customer in the shop come in complaining that the Lefty was not as stiff as he'd been led to believe. I showed him how much wheel flex there was on a Jekyll (Fox with a 15mmQR) compared to his 29" Lefty.
Stock wheels are not always the stiffest builds, but most likely it's not your fork.
Bearings - I don't have to apply any force. As I said it isn't much, just curious if that is normal.

Lets do the obvious, make sure the bolt is torqued to 15 nm.
If that does not fix it...
Take the wheel off, and check each bearing. To get to the small one, you have remove the bolt cap. This is a REVERSE or LEFT HANDED thread. You also need a spanner to take it off. If you find the inner race of one of the bearings loose, you have to replace it.
I hope this helps
Lead by my Lefty............... right down the trail, no brakes.
Some Lefty hubs had small manufacturing tolerance issues a while back, some required to shim the disc side bearings (thin shims installed behind the bearing, requires to pull out the bearing, put a shim or two, put the bearing back.). It might be your issue if the hub is installed correctly and tighten to specs. Cannondale dealers can give you the shims or install them for you but you can make yourself some out of soda/beer cans.
