Those are different being Precision Billet but as you might have noticed the price smarts a bit. I've seen people looking for up to £120/30 for Proshift ones but don't know if they actually sell for that much. As I said if I really thought mine were sellable at anything close to that, they'd be gone already.
Why do you think they're different, they were only made for a couple of years so aren't they the very same?
Regarding value, a chap on here had a few a while ago and they sold easily at the price. viewtopic.php?f=2&t=177486
Have a look at the pic above in thread and at the Precision Billet shifters in link.
Don't they look different to you?
Not notice they have a different mounting method?
Proshift Powertwists use 2 opposing grub screws to grip on to bars, you can see the hole for one in right hand shifter in pic just next to cable entry.
The Precision Billet shifters use a clamping system similar to all other twist shifters that is IMO much better.
There are also additional screws on the rear side from grip on the Billets.
Some of their parts may be the same but they're not the very same, to me anyway.
Thanks for the link regarding price, makes me feel all warm inside.
