WATTSHOP ANEMOI EXTENSIONS – UNDERSTANDING THE DIMENSIONS REQUIRED
This document is a detailed breakdown of the required dimensions. Please note
that do not include your shifters/bar end plugs in any of these dimensions. If
your supplied dimensions fall outside of the standard range this would
indicate you require custom mount plates (dual system) or a custom bracket
(mono system). Custom components are specific to you/bike and can be
manufactured at an additional cost.
A – UCI LEGAL
“Yes” or “No” dropdown for whether you require your position to comply with
UCI regulations. This will have a bearing upon your reach and riser angle.
B – LATERAL BOLT-HOLE CENTRES
This is the lateral bolt-hole center between your two riser stacks. If you
have a mono riser, such as a Trek Speed Concept, please use the mono riser-
specific geometry tool. Note that you may need to remove your extension clamp
block to be able to attain this dimension. In the below image the armrests,
extensions, and extension clamp block have all been removed for ease of
measurement.
C – FORE-AFT BOLT-HOLE CENTRES
These is the fore-aft bolt-hole centers of your riser stacks. This dimension
will determine what fore-aft reach adjust each slotted plate would offer you.
Likely to be in the region of 15-40mm. Note that you may need to remove your
extension clamp block to be able to attain this dimension. In the below image
the armrests, extensions, and extension clamp block have all been removed for
ease of measurement.
D – BOTTOM BRACKET TO REAR RISER BOLT HOLE
We use the bottom bracket as a reference point to align the extensions with
your base bar. This coupled with dimension E will indicate your required
reach. From the center of your bottom bracket measured horizontally (not point
to point) to the rear riser bolt hole of your riser stack. The image below
illustrates the dimension we require (dimension D). You can see this is
measured horizontally. This can be quite an awkward dimension to take, the
easiest way to measure this is to put the rear wheel of your bike against a
wall. Measure from the bottom bracket to the wall and from the rear riser bolt
hole back to the wall. Rear riser stack hole to the wall – BB to the wall =
dimension D. This will be in the region of 430-550mm. 
E – BOTTOM BRACKET TO EXTENSION TIP
This is tied in with dimension D, allowing us to align the extensions at the
correct reach on your bike. From the center of your bottom bracket measure
horizontally (not point to point) to your extension tip. Please note that do
not include any shifters or bar end plugs in this dimension. The same
principle can be applied to dimension D, again remembering this dimension is
measured horizontally. Place the rear wheel of your bike up against the wall.
Measure from the bottom bracket to the wall then measure from the extension
tip to the wall. Extension tip to the wall – BB to the wall = dimension E.
This is likely to be in the region of 730-850mm.
F – OVERALL ARMREST WIDTH AT THE WIDEST POINT
The measurement from the left outside edge of your left armrest to the right
outside edge of your right armrest, taken at the widest point. Taken at the
widest point because you may have your armrests angled in.
G – TOP OF RISER STACK TO THE BOTTOM OF HAND
This dimension allows us to ascertain what degree you currently run your
extensions at and whether our adjustable angled riser will be compatible with
your setup. It is important this dimension is taken from the top of your riser
stack but below your extension clamp block. This is illustrated in the image
below. Again, this can be an awkward dimension to take. To begin with I would
recommend holding the handgrip as you would normally and mark the underside of
your hand, ideally done by wrapping some tape around the extension pole. It’s
easier now to measure from this mark to the floor and then from the top of the
riser stack to the floor. The underside of the handgrip to the floor – top of
the stack to the floor = dimension G. This dimension allows us to
ascertain what degree you currently run your extensions at and whether our
adjustable angled riser will be compatible with your setup. It is important
this dimension is taken from the top of your riser stack but below your
extension clamp block. This is illustrated in the image below.

of the stack to the floor = dimension G.
Please note our standard pole and ergo handgrips are 5cm long. Please ensure you are comfortable with this dimension. If a longer handgrip is required you may wish to take advantage of our custom handgrip offering.
H – HANDGRIP STYLE
We offer numerous handgrip styles. Each has its own advantages and each
affects the reach of the extensions.
- Standard pole; a 5cm long 22.2mm industry standard pole. Accepts all normal style shifting systems. With the extensions at 15 degrees, the pole is at a 50-degree angle to the horizontal and provides a 7.5-degree toe in.
- Ergo (track); an ergo grip that offers a substantial and comfortable handgrip. Not applicable to any shifting system so limited to use on the track only. 7.5-degree toe in and 5cm in length.
- Ergo (Di2 R9150); same style as above but includes a specific cutout for the Shimano R9150 satellite climbing shifters.
- Ergo (Blips); again, same as previous but includes a specific cut out for SRAM Blip shifters.
New handgrip styles are constantly being added to this list. Please check out our website for a complete list of the current offerings. Please note we also offer custom handgrips upon request.
UCI QUERIES
You do not necessarily need to complete these dropdowns but if you are riding
under UCI regulations, we would encourage you to answer “Yes” or “No”. The
tool will then highlight any of your dimensions that fall outside of UCI
compliance.
UNDERSTANDING THE OUTPUT
- ADJUSTABLE ANGLED RISER COMPATIBLE – whether your current angle is compatible with the adjustable angled riser. This is driven by your answer to dimension G.
- RISER ANGLE – the riser angle as determined by dimension G.
- MOUNT PLATE/BRACKET – the mounting plate or bracket required to work with your reach. The measurements for which have been driven by dimensions D and E. If “flipped” it means installed in reverse.
- MIN REACH – the minimum reach you’ll achieve using the specified mount plate/bracket.
- MAX REACH – the maximum reach you’ll achieve using the specified mount plate/bracket.
- OFFSET REQUIRED – how far from you’ll need to set the extension system on the slotted plates to match up with your required position? E.G +10mm means the rear bolt hole of the angled riser is positioned 10mm forward from the back of the slot.
- CAN YOU ACHIEVE YOUR ARMREST WIDTH – whether your specified armrest width falls within the fitment range of the Anemoi system? A really wide armrest position may fall outside of the fitment window and therefore require a custom mount plate/bracket to facilitate fitment.
- INBOARD/OUTBOARD/INLINE MOUNTING – determines whether the mounting plate is mounted inboard of, outboard of, or inline with, your riser stacks. If direct mount this means the mounting plate is not required and the angled riser is fitted directly to the top of your riser stack. Note this option is not applicable to mono-riser stack systems.
- ARM REST OFFSET REQUIRED – how far you’ll need to offset your arm rests on the slotted rest mounting. A positive number means you’ll mount the armrest outboard, and a negative means mounting the inboard.
- ARM REST CLASH – this will determine whether the armrests will clash in the middle. For reference, anything under 200mm overall width will mean the armrests clash in the middle. It is possible to trim the armrests to enable a narrower mounting.
