Re: [RBW] XD-2 as a double crankset - anyone?

I double-i-fied my Fargo by changing the 46/36/24 XD2 triple into a BBG Bashguard/38/24 and switching the 14-25 or so cassette into a 13-25 or perhaps a 12-25 9 speed. 29 1/2” tall 622 X 60 mm tires on Blunt SS rims.

Apart from the chainguard and the new 38 t ring, I changed nothing except the limit screw settings on f and rear derailleurs; I even left the LX fd in the same place as for the triple.

It all shifted perfectly.

Patrick Moore, whose Logic triple run as a BBG BG/44/28 double also works flawlessly.

I'm running a 48/34 using the 110 tabs on a Sugino VT. Coupled with a 12-32 8-speed cassette, it makes for nice gearing for an un- to lightly-loaded road bike. There's also the other way around... use the inner 110s and the 74. Crust is doing this with their Heartbreaker crankset... a 42/26t, 110/74 bcd double that looks a lot like the old Ritchey Logic, with a nifty-looking 42t ring that fairs in around the spider arms.

Pairing this with an 8 speed 11-32 or 9 speed 11-34 looks like yielding useful results:

A 42x11 is a 103" top gear... tall enough for a heads-up sprint with Sean Kelly, (early in his career, King K used to start his sprint in a 52x15 and finish in the 14) or to get you a speeding ticket on most of the descents you'll ever ride.

26x32 or 34 gives a 22 or 21 inch low.

The 8 speed 12-32 and 9 speed 12-36 also look to be their usual flexible and useful selves. If you want to go 10 speed, the SRAM 11-36 looks like The Big Money. 19.6 to 103 inches, 20 gears, no overlaps, even gaps. The only downside is the 3.5-step crossover shift pattern. It's consistent across the cluster, and with indexing it's not a difficult shift to make, but you do have to approach it with a gentle hand.

There's a blue-with-splatters version that my Shoulder Devil keeps telling me to use to build up a "Miami Vice" Specialized or smoke/fade Ironman...or even evil-er, a blue-anodized Vitus 979.

Yeah, works great. Just put a bash guard on the outer ring.

I have multiple XD cranks setup as doubles with a chainguard in the outer position. For example, here's one on my touring bike with 36-24 chainrings, and the chainguard is an old chainring with the teeth hacksawed off and then smoothed down.
