My friend caught this 57cm Charlie prototype for me a few weeks ago - my ideal Riv since I want v-brakes (that my Sam and Cheviot lack). Sadly, this will end up replacing my Sam, but what a replacement! Vs. Sam: No more toe clip overlap, more chainstay length, climbs better (this surprised me), and more comfortable (for me at least).
I swapped nearly everything from my Hillborne onto the Charlie (and vice versa):
Frame - Charlie H Gallop 57cm prototype with canti posts
Wheelset - VO Voyager rims, DT Swiss Competition (double butted) spokes, SP (Shutter Precision) PV-8 dynamo hub in front, Bitex rear hub, Salsa skewers
Stem - Nitto technomic 70mm (IIRC)
Handlebars – Soma Portola (52cm wide at bar ends, 48cm at hoods)
Brake levers – TRP RRL
Brakes - rear CX70 canti, front Shimano BR-R353 (will replace with Tektro 926al which has 85mm arms vs 90mm on the Shimanos ... they work well but the levers don't quite pull enough to feel right with the long arms). Koolstop e-brake pads in front.
Handlbar tape - will replace random rainbow stuff with Newbaums some day.
Seatpost - Nitto S83
Seat - Brooks Flyer (but may replace with B17s or C19)
Crankset - Sugino clipper triple 26/36/46 ... will replace with VO 46/30 double
Cassette – Suntour 11-40t 9 speed
Front derailleur – Riv put on a Blue Line, it is JUST enough range to shift to the tallest chainring, but only just.
Rear derailer - nexus rapid rise, it doesn't have quite enough spring tension with this setup to keep from skipping under hard pedaling, I'll try the XT rapid rise and hope that works better like it did on the Sam.
Pedals – Kona Wah Wah - 118mm x 120mm
Tires – Schwalbe G-One Allround 700 x 50mm
Lights - IQ-XS in front and Secula in back
