I have been riding my trusty IF Ti Deluxe as a single speed now for more than two years. It’s sleek and beautiful frame fits me like and glove but the lack of gears limited my ability to enjoy some rides. Specifically I could not see myself racing the Shenandoah Mountain 100 without gears. With over 14,500 feet of climbing I knew that even if I finished it would not be fun. When I read about the new 1×11 SRAM XX1 drivetrain coming out it seemed like a match made in heaven. I pre-ordered the drivetrain and waited impatiently while I assembled the new wheels. The unique 10×42 cassette uses a new attachment to the hub to accomodate the small 10 tooth cog. Currently only SRAM and DT hubs are compatible. I chose the DT 240 and decided on the new Stans ArchEX rim for its durability, relative lightness(I am a clydesdale rider) and ease of setting up tubeless. Also the new ArchEX rim is wider to provide a better foundation for the wider tires people are running at low pressures.
Finally the new bits arrived and I stayed late one night to install. Weight of my ride before with pedals was 22 7/8 lbs and that includes wheels running with tubes. Weight after installation with a tubeless set-up was 23 1/4 lbs. Only gained 3/8 of a pound to add ten gears! Ridden it a few times so far. Impressed at how quick and easy it is to access gears. One ride was gravel road and the other was two laps on the race course here on the Farm. Have not hear the chain slap yet so it would seem the clutch mechanism in the Type 2 derailleur is doing its job and keeping the chain nice and taut.
