Have intensively informed me before buying. When Thomson stem I'm stuck. Did not regret it. Bin of the stability and the design very impressed. He is not only an eye-catcher on the bike, but also provides security. The fit is excellent. Even relatively small screw forces are sufficient to achieve an excellent clamping action. I use the Thomson stem together with a Syntace Duraflite handlebars. Fits perfectly. Super is that Thomson draws the stem X4 in different slope degrees. I have + - 10 ° selected, this brings me experience has shown the best deal. For me, + 10 ° angle for a moderate sporty comfortable cycling. Overall, milled from one piece aluminum part in which security pairs with formal beauty. It should be so! My absolute recommendation.
