Why the Lynskey Pro GR and not the regular GR?.
I had a new Lynskey GR 270, new this spring, and used it on our local fast paced roadie rides and also on lots of long gravel rides. Two sets of wheels - one set had 43c tubeless gravel tires, and the other had 32c Conti 5000's. I thought the frame handled both really well, i.e. no-hands stable and great on fast gravel descents, and much more responsive with the smaller road tires on road rides. Very nice frame geometry.
But, I thought the frame, and especially the front end (head tube and fork) of my (non-PRO) gravel frame was too stiff. And I'm not a lightweight at 195 lbs. I don't know what they're thinking with the PRO model...
