Features: The matte-black Deda Newton is machined from 2024 T6 aluminum. The silver front cap is held on with four titanium bolts, which, like the fork-steerer clamp, accept a 4mm hex key. The Newton comes in 90- and 95-degree angles in lengths of 105, 115 and 125mm. The Deda N’Bar matches it in graphics and quality.

Likes: Like the Newton road stem, this is a strong, superlight stem, and I find it to be adequately stiff.

Dislikes: Not a one.

Other: You have to very careful not to over-torque the small bolts.

The Deda single-bend bars, namely the N’Bar and BarOne, come only inthe relatively short 560mm length.Test dates: October 2001 to May 2002Conditions: Mountain bike riding in Boulder and MoabWeight: 115mm, 95 degrees: 146 gramsPrice: $130Contact: Deda Elementi, Via Leonardo Da Vinci 21/23, 26013 CampagnolaCremasca (CR), Italy; (39) 0373-75 01 29, fax (39) 0373-75 11 05; Web www.dedaelementi.come-mail:
