Minoura Japan – SG-300M

SG-300M

Quick clamping type T-shaped accessory holder

A convenient device to create extra space for mounting multiple accessories such as head-light or computer on the space for just one item on your handlebar.

The newly developed quick clamp system allows you to mount/dismount SG-300 in mere seconds, so it is easy to carry twin lights in weekdays but remove it for week-end ride.

The new clamp can grab the handlebar much more stiffly, so the lying-down trouble due to the vibration during ride should not occur.
And the new clamp arm is made of durable 1-piece alloy to prevent unexpected breakage caused by fatigue of metal due to the vibration.

New Quick Clamp

Universal type without acquiring any tool

The previous stainless band which was adopted on SG-100N & SG-200 was great to fit wider diameter range from 22 to 35mm in just one SKU, but it required some technique for installing properly and a tool, so you were not allowed to set and remove the holder so easily.
This newly designed quick clamp (named "SpaceMount") enables to set & remove without any tool, so you can carry an extra water bottle only when you need it.

By screwing the bolt on foot of the clamp body, it will change the diameter easily and will fit various sizes of tube diameter. After adjusting the clamping size, just flipping down the lever, it will hold securely.

S-size clamp covers 22 - 29mm diameter and it will fit to standard 22mm handlebar or 27mm seat post. Also you can install on the drop-bar over the bar-tape.

M-size clamp covers 28 - 35mm diameter and it will fit to 32mm oversized handlebar or 32 - 35mm fatter seat post on mini-velo.

Cautions

Important Notices

  • Adjust the clamp size first by screwing the bolt before closing the lever. It is possible to tighten the screw after closing the clamp, but it will not give enough strong clamping power and the holder may be loosened while riding.
  • Make sure the adjusting screw is fully inserted into the clamp body. If the bolt is loosened, you cannot expect enough clamping power.
  • When raising up the lever, do not apply the nail only to avoid injury. The lever is held strongly. Do with your finger.
  • The clamp may compress and break the outer cable due to its strong clamping power if you install BH-100 on the handlebar together with the cable. Clamp the handlebar only.
  • Not compatible with any other dimension than true circle.
  • No tool attached. Prepare an M3 hex wrench by yourself. You are not allowed to use any folding tool kit due to the special design. Use the standard L-shaped hex wrench.
  • Minoura will not be responsible to any trouble due to the quick release function. We recommend you to remove the holder whenever you need to park the bike.
  • Wind the attached transparent sheet around the installing position to prevent scratching problem.
