I've been thinking about this on and off for several years. I don't have a good suggestions but here is some anecdotal info for you to consider. I ride three of my bike on the road regularly. Bike 1 is a Waterford 1250 sport tourer with ~1700 g wheelset, not including the 700x28 mm Conti 5000 tires. Total bare bones weight ~22 lbs. Bike 2 is a Rivendell Sam Hillborne with ~2300 g wheelset, not including the 700x38 mm Gravel King slicks. Total bare bones weight ~27 lbs. Bike 3 is a BMC Mod-Zero with ~1700 g disc wheelset, not including the 650x52 mm UD Cavas in JFF casing. Total bare bones weight ~27 lbs.
After riding the first two for over 15 y over the same routes at similar effort in SW Ohio, I consistently avg 1.5 mph faster on the Waterford. After riding all three the past year on the same routes at similar effort in SW Ohio, I seem to avg maybe 0.5 mph slower on the Mod-Zero than on the Hillborne. Routes vary from hilly to fairly flat and the difference in avg speed is about the same regardless of route. I suspect that the main difference has more to do with rider position than anything else, since the bars on the Waterford are 1 cm lower than saddle, on the Hillborne are about level, and on the Mod-Zero are about 2 cm higher. -Mike Bellbrook OH On Thursday, January 8, 2026 at 6:20:53 PM UTC-5 [email protected] wrote: > TL;DR: Looking to make my Rivendell Platypus faster and more efficient > for long century rides on rough chip seal without losing comfort. > Considering narrower/faster tires (38–40mm) and possibly a lighter > wheelset.
