thunderbolt crank socket drive install

IANAE but my primo DSG is pressift and I couldn't get it to press and fit so I just put it in place enough where it stayed proper and shoved the wheel in my dropouts and tightened my wheel and it all just popped into place now when i take my wheel off it stays on and its no issues... so MAYBE instead of needing a hammer to fit it on, put your cranks on your bike and make them very tight and you should see the sprocket press into place just like my hubguard did...

I'm not just pounding the thing with a hammer. I had a plastic sleeve that fit over the spindle and I was "tapping" it on. I think I'll just do what you suggested and tighten the crank on the frame and see what happens.

Did it come with any thing to tell how to installed the thunderbolt I say just take to a bike shop it will save you time. here the picture. Hope this help If you can't see just click on the picture and zoom in or just downloaded.

Looks fine. That's how mine is. The chamfer on the Tree sprocket isn't as big as it should be, that's why it doesn't fit right up against the arm.

@acedog: no it didn't come with any documentation. Just a triangular box and a warranty card (bought from danscomp). Thanks for the picture(s) though.

@xxohioanxx: I figured as much, just wanted to double check.

Thanks for the help guys I guess I'll just go with it.

Remember its an interference fit too, its meant to have resistance to make sure there is no slop and not to wallow out your sprocket.

Enjoy, looks like a good setup.
