Farley Wheelset

I would like to build a second wheelset for my Farley fatbike. It would greatly simplify my life if I could have separate summer and winter wheelsets. The rims I have now are good for snow, but I could get lighter rims for summer. How much would that cost? Probably in the neighborhood of $1200.

I will use the same Bontrager hubs on this wheelset as I am using on the existing wheels. This should minimize the amount of adjustment I must do each time I swap wheels.

• Rims: Nextie Xiphias 27.5" 80mm Rims - $680 ($340 each)
• Front Hub: Bontrager Rapid Drive Fat Front Hub - $106
• Rear Hub: Bontrager Rapid Drive 108 Fat Rear Hub - $210
• Cassette: SRAM NX Eagle PG-1230 11-50t 12-Speed - $108

• Spokes: DT Competition Race Double Butted Spokes, Black, J-Bend
• Spoke Nipples: 14mm DT Swiss
• Rim Tape: Teravail (Whisky) 65mm x 4.4m
• Brake Rotors: SRAM Centerline, 160mm, 6 Bolt
• Valve Stems: Wolf Tooth, 44mm

• Spoke tension meter
• Disc rotor adjustment tool

Status:

The wheels have been built. The rim tape still allows a slow leak of air, and I don't like the valve stems I installed. I will make a third attempt to tape the rims, and if it doesn't get any better, I give up and put sealant in the tires. Alternatively, I could rebuild the wheels neoprene washers.
