DC 3.0 Stem

What Our Gearhead® Experts Are Saying:

"The Syncros DC 3.0 Stem stood out to me because of how many length options it covers in one model. I settled on the 70mm for my down country setup, and the 0° rise paired with a moderate riser bar puts my cockpit in exactly the right position for technical climbing and descending. The 4-bolt face plate has been completely solid and creak-free through a full season of mixed XC and trail riding."

Down country riding has carved out a genuine identity in mountain biking, demanding a bike and cockpit setup that can climb efficiently, descend with confidence, and handle the full range of terrain that falls between a dedicated XC race course and a proper trail bike zone. The Syncros DC 3.0 Stem is built specifically for that context, offering a neutral 0° rise geometry across five lengths from 50mm to 90mm that covers the full spread of rider proportions and fit preferences within the down country category.

The wider length range compared to the shorter AM-focused stems reflects the reality of down-country riding, where longer stems remain appropriate for riders who want a more stretched, efficient position on climbs while still needing the responsiveness and bar control that a flat rise geometry provides on technical descents. The 4-bolt face plate design accommodates riser bars cleanly and distributes clamping force evenly around the contact zone, keeping the bar locked in without stress concentration regardless of bar diameter or rise within the 31.8mm clamp standard.

The forged and machined AL6061 body delivers reliable stiffness and durability across all five length options, and the 1 1/8in steerer compatibility makes the DC 3.0 a direct fit for the Scott Spark 900 and the broader category of cross-country and down country frames built around that steerer standard. Corrosion-resistant Torx T25 steel bolts handle all clamping duties with hardware that holds torque cleanly through repeated service. At 170 grams and shipping with a top cap and bolt for a complete installation, the DC 3.0 is a thoroughly considered stem for riders who want their cockpit setup to match the ambition of their riding.
