For the sake of accuracy, the update didn't say "under" or "below" 20 pounds.
Even a 1.5# reduction looks costly.
But my "costly" might be someone else's cheap.
$500 might do it, but I wouldn't spend it to make the change myself.
If Helix offered a weight reduction package based upon substituting lighter
components, this could be pretty cost effective...much cheaper than our
buying duplicate but lighter components after receiving the new bike.
I'd rather have Peter select the components, Helix do the assembly, while
I do no work other than paying a little extra. I could go for that.
