DW 9907CR Clamp-On Bass Drum Spur, Right Side
The 9907CR is a clamp-on bass drum spur, designed for the right side of the drum. It solves one specific problem: a bass drum that rolls or leans because a tom or a cymbal is loading only one of its sides.
What sets it apart
- Clamps onto the bass drum hoop
- Designed for the right side of the drum
- No drilling: nothing to screw into the wood
- Comes off for transport, without leaving a mark
- Used alone or with the left-side version
The drum that rolls, and why it happens
A small bass drum, or a converted floor tom, often has no spurs at all. Resting on its side, it holds its place as long as the load is even, but as soon as a tom holder or a cymbal is mounted on one side, the drum slowly twists as you play.
The drummer notices at the end of the first song: the pedal has turned, the beater no longer hits the centre of the head, and the sound has changed. A spur on the loaded side restores the balance.
Clamped on, not screwed in
This spur does not go into the shell. It closes around the hoop, which means it installs in a minute, comes off for transport and leaves no trace. For a vintage drum, a collector's drum or a drum you plan to sell, it is the only sensible approach.
That is also what makes it usable on a borrowed bass drum, where drilling is simply out of the question.
Why it comes in two versions
The clamp is directional: it tightens onto the hoop one way and the spur points forward. So you need one version for each side of the drum. This one is for the right side; the left-side version is a separate product.
Left and right are judged facing the drum, looking at the front head, in other words from the audience's point of view.
To be clear: the manufacturer does not publish a spec sheet for this model. We therefore describe its function and its side, without stating a spur length or a finish.

Frequently asked questions
- Right or left: how do I tell?
- Look at the front head, from the audience's side. This one is the right-side version.
- Do I need to drill the shell?
- No. It clamps onto the hoop and comes off without leaving a mark.
- Does it replace a pair of original spurs?
- It is an extra support, mainly for the loaded side. A bass drum that is already well balanced does not need it.
