Stems for threadless systems – Aheadset®

In the case of BERGAMONT bikes with Aheadset® headsets the stem also serves

to adjust the bearing preload. If you change the position of the stem, you have to

readjust the bearing play (see the chapter “The headset on the BERGAMONT bike”

and the manuals of the component manufacturers).

The vertical setting range is determined by the intermediate rings, also referred to as

spacers (b). In the case of flip-flop stem models the stem can be mounted the other

way round (c) to achieve a different handlebar height.

For modifications unscrew the bolt at the top of the fork steerer tube which serves

to adjust the initial bearing pressure, remove the Ahead cap and release the bolts

on either side of the stem by up to three turns (d). Remove stem and spacers from

the fork steerer tube. In doing so keep hold of both frame and fork to prevent the

fork from slipping off the head tube. You can determine the handlebar height by the

arrangement of stem and spacers. Slip the remaining spacers onto the fork steerer

tube above the stem. Adjust the headset, as described in the chapter “The headset

on the BERGAMONT bike“.

If you want to turn the stem around, you have to also release the bolts of the faceplate

securing the handlebars (e). If the stem is ﬁtted with a cap, you can simply take

out the handlebars at this point. If it is not fitted with a cap, you have to remove the

handlebar fittings.

Mount the handlebars and, if necessary, the handlebar fittings, as described in the

chapter “Adjustment of handlebar tilt and brake lever/shifter units on BERGAMONT

road bikes and BERGAMONT cyclo-cross bikes” and/or in the manuals of the

component manufacturers.

Check after the adjustment or assembly, whether the handlebars are firmly seated

in the stem by trying to rotate the handlebars downwards (f). Verify whether the

handlebar/stem-combination can be turned relative to the fork. Do this by taking

the front wheel between your knees and trying to twist the handlebars. If there

is movement, carefully tighten the bolts a little more by using the torque wrench,

observe the maximum torque value and check again the proper fit.

Tighten carefully by approaching the prescribed maximum torque value in small steps (0.5

Nm increments) and check in between the proper fit of the component.

DANGER!

The stem is one of the load-bearing parts of your BERGAMONT bike. Changes to it

can impair your safety. If you are in doubt or if you have any questions, contact your

BERGAMONT dealer!

DANGER!

These routines require a certain amount of manual skill and (special) tools. Ask

your BERGAMONT dealer to explain you both function and adjustment of your

stem or let him do that work.

DANGER!

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 BERGAMONT bike”, directly on the components and/or in the manuals

of the component manufacturers.

DANGER!

Stems come in varying lengths (a) 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 BERGAMONT or SYNCROS. Your BERGAMONT dealer will be pleased to

help you.

CAUTION!

If you choose to use the product of another manufacturer, make sure it is

compatible with the BERGAMONT/SYNCROS components. BERGAMONT

assumes no responsibility for problems resulting from the use of non-BERGAMONT/

SYNCROS products. Make sure the handlebar/stem-combination is approved by the

handlebar and/or stem manufacturer.

CAUTION!

Make sure the handlebar clamping area is free of sharp edges.
