Apex

close-window open-window

The Renthal Apex combines All Mountain strength, Enduro stiffness and XC lightweight.

Unique 240deg handlebar clamps allow much of the stem body material to be removed, whilst retaining the strength and stiffness demanded by modern, wide handlebars.

The Apex is fully CNC machined, featuring an oversize centre bore, extensive 3-D machining and external webbing to maximise structural strength and stiffness and minimise weight.

Renthal® Apex™ : Designed to ride faster, jump further and last longer.

CNC Machined

The Renthal Apex is CNC machined from a solid billet of 2014 aluminium with 7075 aluminium clamps. These materials were specifically chosen for this application, to give the highest strength to weight ratio.

240 degree clamps

The clamps are inserted over the small diameter section of the handlebar and slid into the centre, giving a 240 degree wrap of the handlebar.

+/- 6 Degree Angle

The stem body can be flipped to give either a plus 6 degree or minus 6 degree rise. This allows the correct bar height to be achieved with any wheel size or head tube length.

Oversize Centre Bore

The unique handlebar clamping system opens up the front of the stem, allowing an oversize centre bore, to increase stiffness and strength.

3D Machining

Extensive 3D machining and external webbing increase the torsional stiffness of the stem, whilst keeping weight to a minimum.

High Quality Finish

After CNC machining, the stem components are anodised and laser marked to give a very high quality and durable finish.

EQUIPMENT REQUIRED – Torque Wrench, 4mm Hex Socket Bit, Waterproof Grease.

Important - Follow all fitting instructions in order

STEERER TUBE PREPERATION

  • The Renthal Apex stem requires a 28.6mm (1 1/8”) steerer tube (check prior to installation).
  • Ensure the steerer tube is the correct length – no more than a 3mm gap from the top of the stem to the top of the steerer tube (Fig. 1). If the steerer tube requires modifying to fit, ensure it is cut level.
  • Ensure all sharp edges and burrs are removed from the steerer tube and the external surface is both clean and dry.

INSTALLATION INSTRUCTIONS

• Remove all screws. Grease the threads and under the heads.

• Slide the stem onto the steerer, either way up depending on the rise spec required. Fit the top-cap and tighten the pre-load screw to the manufacturer’s specified torque.

• Place one of the gold handlebar clamps over the narrow section of your handlebar (Fig. 2) and slide to the centre, ensuring the ‘Lower Clamp – No Gap’ marking is at the underside of the bar and facing outwards. If your handlebar has a logo, use the gap in the clamp to avoid marking it. Repeat with the second clamp (Fig. 3).

fig3

• Hold the handlebar against the stem body and rotate the first clamp until the lower section contacts the stem (Fig. 4). Insert the screw and tighten until finger tight. Repeat with the second clamp.

fig4

• Insert the two upper handlebar clamp screws and thread in 3-4 turns.

• Tighten both lower clamp screws to 5Nm (Fig. 5).

fig5

• Centre the handlebar and set your required angle. Tighten the two upper handlebar clamp screws to 5Nm (Fig. 6).

fig6

• Insert the steerer clamp screws, align the stem and tighten to 5Nm (Fig. 7).
