Universal Rear Shock Dummy Tool | PRO Version

165 mm to 250 mm (and up to ~266 mm for legacy sizes). One full rotation = 10 mm of length change. Set your eye-to-eye and lock it in seconds.

• Full top-section swap: Unscrews completely for instant conversion between eyelet and trunnion. Each adapter self-aligns perfectly perpendicular.
• High-strength polymer body: Thicker, stiffer, and designed to withstand repeated workshop use without flexing.
• Maintenance-friendly interface: If the top gets snug, insert a screwdriver in the slot to unscrew. No need to overtighten.
• Heavy-duty load capacity: Over 20 kg of static load (not for riding or sitting).
• Thread-and-align system: Rotate until the Triangle marks your length. Going 10 mm under is still good practice for eyelet clearance.

The PRO version replaces both the base and small trunnion setup. Ideal for repeated configuration changes and shop use. If you only need to support one frame occasionally, the standard version is enough.

Convert inches × 25.4 mm to set your length. Example: 7.875" → 200 mm → set the tool to 195 mm.

Works with older imperial lengths (8.5" / 216 mm, 9.5" / 241 mm, 10" / 254 mm, 10.5" / 266 mm) by extending the threaded body slightly past the last mark.

• Main adjustable body (165–250 mm+ range)
• Swappable top section (Eyelet & Trunnion)
• Pre-threaded M10 eyelets for universal fit
• The only exception is Giant: their lower mount uses a 15 mm axle. Contact me if you have this.

This is not a riding or load-bearing component. Use only for maintenance, storage, or transport. The bike can be rolled around, but do not sit on it or apply dynamic loads. Tested on 10+ frames, but some exceptions may exist.
