This is a nice Thomson Elite mountain bike stem in a 110mm size (with 5 degrees of rise or drop). This is the cool older style with the recessed steerer binding mechanism. I really like the smooth, flowing lines of this model. This stem fits 1-1/8” threadless steerers. The handlebar clamp diameter is 25.4mm. This stem is in complete, fully functional, and in very nice condition. I have uploaded large photos. Please take a look. Thanks! I have uploaded large photos.
