I am also a Quest V1.0 , AND a Softrider V1.0 owner, that is how I know that the Silvio V1.0 and especially the S30 is faster!
I have ridden the Softrider 1,600 km, with 3 Ortlieb bags, using Hostels for overnight stays, around the South Island of the LITTLE island near us, with Kiwi birds on it, as seen on my photo outside the Cardrona Pub!
The Quest was used in USA to cycle 2,800 km from Canada to Mexico in 2011 on a Van supported ride with ACA, hence a small bag for waterproofs, leg warmers, tools and tubes.
The Silvio V1.0 was used to cycle 3,500 km across the Rockies twice in Canada and USA on Van supported rides with Cycle Canada (Best), Cycle America (Worst), and Cycle Oregon (very Good).
The Arkel rack bag, and rack were very good for van supported rides, but I am in the SLOW process of adding 16 mm dia. AL supports from the frame to the rear of the Arkel rack so I can carry 3 Ortlieb bags again, behind the rider! I will do the same for the S30. Once I found the Arkel Randonneur rack could be fitted with one hole drilled in the seat back, i stopped ridding the other bikes, which had racks, as the Silvio, for me was MUCH faster and HEAPS better ride over the VERY rough South Australia bike tracks, and minor roads!
The Disk brakes on the Softrider (added) and the Quest are magic compared to the rim brakes on the Silvio v1.0,, and that is a major reason for the S30 + the 28 degree seat back!
The Quest was modified with drop bars and brifters to make it as close to the Silvio V1.0 as possible, before the 2013 trip to USA and Canada, but the Silvio Air bag suspension, direct slider and boom, and and 700 wheels won out over the Disk brakes!
I will attempt to change the Quest boom/slider to Emaljay's arrangement, once I can find a tube expander for the 1 1/16" ID boom, to expand it out to 1 1/8" to dramatically stiffen up the Quest power triangle.
