Not only does the XM 1550 TRICON® look fast, it also combines XC weight with trail riding strength. The meticulously perfected components mean zero compromise for pure riding enjoyment.
DT Swiss thru bolt: The DT Swiss thru bolt system is 100 % compatible with the quick release standard. Instead of a thin 5 mm shaft, the DT Swiss thru bolt is an alloy bolt with a diameter of 9 mm on the front hub and 10 mm in the rear. For mountain bikes with disc brakes, a thru bolt connection is a substantially stronger and therefore safer connection.
Thru axle: Contrary to the DT Swiss thru bolt system, a thru axle connection is not compatible with the quick release standard. The thru axle is always an integrated part of the frame or fork. The diameter of those axles is generally 20 mm in the front and 12 mm in the rear.
Center lock®: Center lock rotor mounting system licensed by Shimano®, Inc.
IS (6-bolt): International standard for disc brake mounting with 6 bolts.
Double butted: Double butted spokes are thinner in the center than at each end due to DT Swiss‘ unique cold forging technology which reduces the diameter of the spoke for better strength to weight performance with improved elasticity. Only the cold forging process assures the highest mechanical quality.
Bladed: These spokes have a flat (bladed) middle section for better aerodynamics. As in our butted spokes, the coldforging process is used for optimization of its mechanical properties.
Prolock: A patented liquid injected into the nipple thread allows for extremely durable wheel builds.
Tricon: Patented tubeless wheel system with an ideal stiffness to weight ratio.
RWS: Patented wheel mounting system. Stiffer, safer and more user friendly than conventional quick releases. 100 % disc brake compatible.
SBWT® welded (strength boost welding technology)®: First two small blocks (sleeves) are pressed in both ends of the rim to stabilize the profile during the welding process. During the welding process the two ends move towards each other to achieve a solid joint. Then the seam gets CNC machined. This process guarantees the best rim joint.

These came on my Trance - they are light and strong and rode great.
Then I ran into a short small stump that lodged between rim and fork putting the rim out of true. I have built lots of wheels from scratch and have re-trued many wheels. Totally struck out trying to true this thing. It is totally user unserviceable. I saw a Tricon truing "kit" for $160?? My friend found a compatible spoke wrench - torx-style, like Mavic but smaller diameter. I read that DT uses a super strong loc-tite type binder so expected some difficulty but the spokes simply twisted and the nipples would not release to allow truing. I held the bladed spoke very near the nipple with a padded vice grip but it simply twisted in the inch between the grip and the nipple. So, I am out a wheel and my bike until I get a replacement wheel. Will not buy a DT Swiss wheel henceforth. Also, their customer service is appalling - I emailed them about this and nothing after a week. Another fellow in a MTB review forum was communicating back and forth for 4 months and still no satisfaction with his wheel. Sobeit.
