Details
Bottom bracket style mounting and fantastic frame protection

The DropStop is a new type of anti-chain drop device for road and mountain bikes. The DropStop is ideal for full suspension mountain bikes or road bikes with non-round or oversize seat tubes which make it impossible to mount other types or anti-drop devices. The DropStop is mounted and firmly clamped into position using the bicycles bottom bracket. The DropStop totally protects the frame from chain damage due to chain-drop and keeps the chain running on the inner chainring.

- Simple design for both road and mountain bikes
- Hardened aluminium construction with nickel plating
- No seat tube mounting required
- Excellent frame protection

The DropStop is sold in two sizes. The longer size is for road bikes and will protect up to a 39 tooth small chain ring. The shorter size will work with most cross and mountain bikes with small chain rings up to 32 tooth.

Would this also fit a square taper bottom bracket, or only HTII

We cannot say, without your bike being here we cannot guarantee if this will work or not. Most likely no as Square taper BBs are narrower in diameter than more modern systems.

How thick is the spacer section?

I'm assuming this goes in the same place as a bottom bracket spacer. How thick is the spacer section? I want to ensure I maintain my chain-line.
0.9mm thickness of the spacer section.
Many thanks
