DE. S-BOARD
Clip-on front mudguard for racing bikes, cyclocross bikes, hybrid bikes and gravel bikes. For a max. tyre width of 38 mm. The S-BOARD is the ideal companion for our S-BLADE
rear mudguard. Its light, double-hinged quick release tting system also ts aero forks.
Mounting instructions: The S-BOARD is to be mounted on the fork so that there is a minimum clearance of 1.5 cm between the mudguard and the tyres
all-round. CAUTION! Only tighten the screws with max. 1 NM!
1
Initially position at point A the mudguard on the fork so that the minimum clearance to the tyre of 1.5 cm is ensured. This can be ascertained by pushing it up or down (Arrow
B). Now tighten the quick release rubber around the fork and hook it into the fastening tabs, so that it is unable to slip on the fork (see 1a.).
1a
Use the enclosed paintwork protection in order to protect the frame. Please see the section entitled »Permanent attachment of the mudguards« for information regarding the
permanent attachment of the mudguard with not enclosed cable ties.
2
Now adjust the angle of the mudguard, by loosening the screws and moving the mudguard, within the elongated eyelets at the end of the plastic stays, so that the clearance
between the mudguards and the tyres is a min. of 1.5 cm all-round.
Now retighten the screws (max. 1 NM) so that the mudguard now rmly remains in position.
2a
Where necessary, carefully shorten the clamping rubbers with a scissors so that the ends cannot come into contact with the wheel spokes.
Permanent mounting of the mudguards
In order to fasten with quick release clamping rubbers, the S-BOARD can also be attached with cable ties (C). This type of fastening is only suitable for a permanent mounting and
as protection against the S-BOARD being stolen from the bike. In order to assemble the mudguard, use a further 2 cable ties per side in addition to the clamping rubbers. Ensure
that the cable ties run precisely in the grooves provided for this purpose. Pull the cable ties as tight as possible in order so that slipping cannot occur. Carefully cut the protruding
ends of the cable ties using scissors.
Safety instructions!
Before each journey, check that the mudguard is sitting correctly. If the minimum distance between the mudguard and the tyre is not observed, the mudguard may become
damaged and, in the worst case scenario, could lead a crash. Therefore, it is essential that the minimum distance of 1.5cm is observed during assembley. Ensure that the awless
function of the brakes is guaranteed and that the mudguard does not come into contact with the moving brake parts. Due to the eect of UV radiation, the clamping rubbers are
subject to natural aging. Regularly check the condition of the clamping rubbers and promptly replace them in the event of damage. Please check screws before each ride to insure
they are tight to 1NM.

Do you recommend S-Board?

Frequently Asked Questions

A

The S-Board is designed for tyres up to 38 mm wide. Ensure a minimum clearance of 1.5 cm all around between tyre and mudguard during installation.

Is this answer helpful?

A

Yes. The S-Board features a light, double-hinged quick-release fitting that is compatible with many aero forks, allowing secure attachment without interfering with fork profiles.

Is this answer helpful?

A

For permanent, theft-resistant mounting use two additional cable ties per side threaded through the supplied grooves in addition to the rubber clamps. Pull them tight and trim the excess; this secures the guard more permanently than the quick-release straps alone.

Is this answer helpful?

A

Before every ride check the 1.5 cm clearance, confirm screws are tightened to 1 Nm, and inspect rubber clamps for UV damage. Replace worn clamps and retighten screws as needed to avoid slippage or contact with moving parts.

Is this answer helpful?

A

The mudguard includes paintwork protection film to help prevent damage, but SKS disclaims liability for frame or carbon finish damage. Proper use of the protection film and regular cleaning around attachment points reduces risk.

Is this answer helpful?

A

Basic tools are minimal: a 2.5 mm hex (Allen) key may be used for the screws, and scissors for trimming rubber straps or cable-tie ends. A 1 Nm torque driver is recommended to avoid over-tightening.

Is this answer helpful?

A

SKS provides mounting instructions and a YouTube mounting video demonstrating positioning, adjustment and permanent cable-tie installation steps for correct assembly and safety checks.

Advantages and Disadvantages

Advantages

  • Lightweight clip-on design suitable for road, gravel and cyclocross bikes.
  • Double-hinged quick-release fitting fits aero forks and is tool-free to position.
  • Includes paintwork protection to prevent clamp-induced finish damage.
  • Permanent mounting option with cable ties for theft resistance and extra security.
  • Adjustable angle and elongated eyelets allow precise 1.5 cm tyre clearance.
VS

Disadvantages

  • Maximum tyre width limited to 38 mm, not suitable for wider mountain tyres.
  • Screws must be tightened to a very low torque (max 1 Nm), requiring care and a torque driver.
  • Rubber clamping straps are UV-sensitive and require periodic replacement.
  • Permanent cable-tie mounting is irreversible without cutting ties.
  • May need careful trimming of strap ends to avoid spoke contact.

Product Description

SKS S-Board mudguard Manual

The SKS S-Board mudguard is a lightweight, clip-on front guard designed for road, cyclocross, hybrid and gravel bikes. Engineered in Germany, it accommodates tyres up to 38 mm wide and pairs well with the S-BLADE rear mudguard to provide comprehensive splash protection on wet or muddy rides. Its low-profile design and double-hinged quick-release fitting make it compatible with aero forks while keeping weight and drag minimal.

Easy to fit, secure in use

Fitting the S-Board is straightforward: position the mudguard on the fork with a minimum 1.5 cm clearance to the tyre, adjust vertically to achieve that gap, then secure using the rubber quick-release straps and tighten the fastening screws to a maximum of 1 Nm. The plastic stays have elongated eyelets that allow angle adjustment before final tightening. A paintwork protection strip is included to prevent contact damage to the fork finish during clamping.

Permanent mounting option

For a theft-resistant, permanent attachment, the S-Board accepts additional cable ties routed through dedicated grooves alongside the rubber clamps. Use two cable ties per side, pull them tight, and trim the excess. This method secures the guard firmly while maintaining the correct clearance and preventing slippage over rough terrain.

Safety and maintenance

Always check the 1.5 cm clearance and screw torque before each ride — insufficient clearance can result in damage or crashes. Ensure the mudguard never contacts brake parts or moving components. The rubber clamping straps are UV-sensitive and will age; inspect them regularly and replace if showing wear. Re-tighten screws to 1 Nm as needed.

Practical tips

  • Trim rubber strap ends if they risk contacting spokes.
  • Use the included paint protection film to avoid damage to painted or carbon forks.
  • Follow torque guidance exactly: screws must not exceed 1 Nm.

Notes:

  • Maximum tyre width: 38 mm.
  • Compatible with aero forks thanks to the double-hinged quick-release system.
  • Made in Germany; assembly video available on YouTube.
