JensonUSA "Shimano XTR M986 Oe Front Derailleur" $69 listed as 31.8mm with a pic of a direct mount. In reality it is the XTR 34.9mm high clamp with 31.8mm shims pre-installed (28.6mm shim are not included as with the retail version). I received mine today, pulled out the shims and mounted it. Nice piece, btw I used a coupon "LOYAL13" for $5 off a $25+ order, as usual free shipping on $50+ orders. Not a bad buy for $64 IMO
