Instructions:
This stem only fits 1 1/8" (28.6mm) steer tubes and 1" steer tubes when using a reduction shim.
Handlebars must have the following diameter at the stem clamping area (+/- 1 mm):
MTB-handlebars: 25.4 mm
Road bike handlebars: 26.0 mm
Oversize handlebars (road & MTB): 31.8 mm
Do not use this stem if you are not absolutely certain it fits your handlebar!
The upper end of the steer tube must not be more then 2mm below the upper edge of the stem. The steer
tube must therefore protrude at least 37.5 m from the uppermost bearing cup/spacer.
Do not grease the clamping areas (neither handlebar nor steer tube)
Bolts that have been tightened too much need to be replaced because they damage the thread of the stem.
Please adhere to the torque values given here:
For carbon handlebars, we recommend using the lowest value.
Torque M6 bolts: 8.5-11 Nm
Torque M5-bolt: 5-6.5 Nm
The head of the M5 bolt is very low and requires a high-quality, exactly made tool.
In general, always follow the installation instructions of the fork and handlebar manufacturer!

Check the stem for damage from time to time and exchange damaged parts, if necessary.
Depending on how heavy damage caused by crashes etc. is, the lifespan of your stem may either be
reduced or it may be necessary to replace it completely (in case of micro-fissures). Damage to the surface
and the resulting corrosion (grey oxidation) should not be underestimated!
Spare parts can be bought from TUNE.
Installation:
Before tightening the bolts, some thread lock compound should be put on the thread and the bottom side of
the bolt heads should be treated with neutral grease. Tighten the bolts alternately to achieve an even torque
distribution.
Tip: only use Allen keys of the highest quality (with very little play). Tools with ball heads or similar should
not be used!
