ADJUSTMENT OF THE HEIGHT OF THE HANDLEBARS
The height of the handlebars compared to the saddle and the distance between saddle and handlebars determine how much your upper body will be inclined forward. Lowering the handlebars gives you a streamlined position and brings more weight to bear on the front wheel. However, it also entails an extremely forward leaning posture which is tiring and less comfortable, because it increases the strain on your wrists, arms, back, upper body and neck.
There are three different stem systems that allow vertical adjustment of the handlebars, the conventional (c), the adjustable (d) and the Aheadset®-stem (e). These systems require special knowledge. In this regard, the descriptions hereafter may be incomplete. If you are in doubt or if you have any questions, contact your GRANVILLE dealer.
WARNING
The stem is one of the load bearing parts of your GRANVILLE bike. Changes to it can im- pair your safety. If you are in doubt or if you have any questions, contact your GRANVILLE dealer!
These routines require a certain amount of manual skill and (special) tools. Ask your GRANVILLE dealer to explain you both function and adjustment of your stem or let him do that work.
The bolted connections of stem and handlebars have to be tightened to the prescribed torque values. If you disregard the prescribed values, the handlebars or stem may come loose or break. Use a torque wrench and never exceed the maximum torque values! You will find the prescribed values in the chapter «Recommended torque settings for your GRANVILLE bike», directly on the components and/or in the manuals of the component manufacturers.
Stems come in varying lengths (f) as well as shaft and binder tube diameters. A stem of inappropriate dimension can become a source of danger: Handlebars, stems or forks can break, resulting in an accident. When replacing any parts be sure to only use parts that bear the appropriate mark and, to be on the safe side, original spare parts from GRAN- VILLE or SYNCROS. Your GRANVILLE dealer will be pleased to help you.
