I shopped pretty carefully for a 34.9mm 200mm dropper for my new Evo, they all weigh a lot. The lightest I found was 710 grams for the OneUp. That's a solid product with a great weight/ adjustability/ low stack/ and low weight for what it is. PNW told me they weighed one for me at 640ish and I ordered it, and it actually weighed over 750 grams so the order was cancelled. after that not sure I'd trust any of their measurements.
In the end, I realized that utilizing the included dropper shim and just reusing my 30.9mm 175mm KS Lev Ci, which weighs exactly 400 grams made a lot more sense.
Now if anyone releases a 34.9 diameter. 200mm travel carbon dropper that weighs less than 600 grams, I'm in. I'd take a weight penalty for the extra drop.
BTW, the included Spesh steel shim weighed 41 grams so consider that. Just ordered a Cane Creek Aluminum shim to replace it. Probably be the cheapest and most reliable 20+ grams I've ever saved.
