The new Ergotec Charisma and High Charisma stems are not just a technical highlight but are also really stylish in appearance. Special forging technology makes it possible to design the stems in such a way that the fork steerer clamp is closed in the upper section. As a result the stem has an elegant look and gives the whole a more harmonious and coherent design.

ConsProbably much too high for most people, no oppertunity to fine tune the position using spacers.
ProsRaises the handlebars alot, without needing new brake cables.
My new bike has a very long reach and the handlebars were also too low. I didn't like using the drops and got sore hands / neck / back quite quickly on longer rides. The new stem has fixed that problem as the very high rise has shortened the reach and rised the bars alot. I can now comfortablely use all possible hand postions with ease. In truth i have probably overcooked it (now too short and too high) and should have gone for the 'charisma' rather than the 'high charisma' (and I may do so later, or chose an adjustable stem) but the bike is useable as it is. The stem itself was good quality, easy to fit, and I didn't realy find the bolts soft at all. I didn't need new brake cables with this stem as would have been the case with a simple steerer extension, also one less peice of metal on the bike. I needed to add an extra 5 mm spacer because of how the stem fits over the top of the steerer tube. Would probably only recommend it if you wanted a very dramatic cahnge in riding position.

ConsAllen key bolts are of poor quality
ProsRaises the hanldbar by 3"
The stem itself is good.
The allen key bolts are not of good quality and are quite soft. Not what one expects from a German manufacturer.
Has eased pressure on the wrists and the new posture is good in traffic.

Hi , does this 90 or 110 mm dimension refer to the lenght of the extension angled upwards or the distance from the top cap to the clamp measured as a horizontal line ,

thanks ,


The length of this stem is measured along the body itself from the centre of the top-cap bolt to the centre of the handlebar clamp.
