Thanks Stefan. I went with the PFP's based on your advice awhile back. As far as the weight of the SL, I easily lifted the bike the other day over several rail road tracks.
Finally took a gravel ride on my new Pathfinder Pro's, performed quite well. I was pleasantly surprised how well they rolled on pavement (tarmac) . No resistance that was noticeable. Picture is in Salida, Colorado. gravel road up 'S" mountain.
Interesting. I would imagine that some of the large companies are noticing the success Specialized is having with the SL I gamble to say that we might also see some new gravel related e-bikes hit the market.
