Item # TTT001N


The story of the difference between 3T's Mountain Pro Stem and the more expensive Team model is told in grams. The Pro Stem is made from 2010 aluminum and fastens with chromoly hardware, which adds a claimed 15g to its weight compared to the Team Stem's 7075 T6 alloy and titanium bolts. Of course, the Pro Stem's claimed weight is still just 120g, and the virtually bombproof alloy is buttressed even further with a wide clamping stance and a squared body. These formal design elements help resist torsional flex and ensure that the Pro is equal to the biggest of hits.

Description here states 10 deg angle, but on the actual part it explicitly says -10 (not +/- 10). Is it save to use this with positive rise regardless?

Yes indeed it is safe to run a stem in any direction (positive or negative).
