2012 Moots Psychlo X RSL — Weight (variations)
See the build summary on the previous page, because weight numbers on this page refer to the original build weight.
The Moots Psychlo X RSL cyclocross bike can be built up as a do-it-all bike, good for offroad and onroad use, with very respectable bike weight for its ultra-sturdy frame.
This pages examines some build variants relative to the original build a specified on the build page, which is a complete ready to ride setup with pedals, sensors, cages, offroad tires, etc at 18.4 pounds.
Weight with various clincher tires on the hand-built wheelset
Considering tire and tube weights (as weighed), we can compute the bike weight with various tire + tube combinations.
Note that 25C tires take a much lighter inner tube than 28C tires (Schwalbe tubes for the 28C, Bontrager for the 25C).
Schwalbe Racing Ralph 700 X 33C: 594g + 262g = 857 g +284g = 18.4 lb bike
Schwalbe Ultremo ZX 700 X 28C: 461g + 262g = 723 g +200g = 18.2 lb bike
Schwalbe Ultremo ZX 700 X 25C: 435g + 138g = 573 g +0g = 17.8 lb bike Lightweight Obermayer + Veloflex Record: = 16.4 lb bike (estimated)
The Moots Psychlo X RSL cyclocross bike with a hand-built aluminum wheelset compares very favorably to a road bike with a similar wheelset! This is a valuable data point for anyone considering the Psychlo X RSL as a do-it-all bike.
SRM DA 7950 power meter vs Cannondale Hollowgram SL crankset
Switching out the Cannondale Hollowgram SL crankset with N10 rings for the SRM DuraAce 7950 power meter (which requires a bottom bracket adapter) yields an 18.7 pound bike with the 700 X 28C Ultremo ZX setup above, or 18.9 pounds with the Schwalbe Racing Ralph knobby tires.
In short, the SRM DA7950 crankset adds 1/2 pound over the Cannondale Hollowgram SL non-power crankset.
