Recommended for open bore options

The SPIKE-GT is a 9" sound with a smooth tapered entry and three repeating wave-and-valley zones along its length, finishing in a ridge-textured base segment for localized tactile control.

Details

  • Insertable length: 9"
  • Entry tip: tapers up to a 10 mm (30 Fr) primary groove
  • Primary valley: 8.5 mm (25.5 Fr)
  • Repeating wave zones: 10 mm (30 Fr) peaks, 9 mm (27 Fr) valleys
  • Final base segment: ridge-textured, 10 mm (30 Fr)
  • Base: 18 mm (54 Fr) flange, non-insertable

How it works

The tapered tip glides in smoothly, then rises to an immediate 10mm diameter before dipping into an 8.5mm primary valley. From there, the shaft repeats a gentle expansion-and-reduction pattern — climbing back to 10mm, dropping to a 9mm valley — twice more, giving a rhythmic, wave-like feel along the canal. It finishes with a ridge-textured 10mm section right before the wide 18mm base flange, giving clear tactile feedback and a stable external stop.

Choosing your silicone firmness

Bob recommends #10 (Medium) or #18 (Firm) for this piece.

Color options

#18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.

Please note

This is an intermediate piece — a full 10mm maximum diameter across a 9" insertable column is a meaningful step up for users ready to move beyond baseline sizes.
Use appropriate lubrication and never force insertion. Stop immediately if you experience pain, bleeding, or significant discomfort. Inspect the sound before each use and do not use it if damaged.

An amazing sound with an addicting shape and wonderful sensations at the end.
I got this sound in the hardest silicone, as someone who cannot usually fit 10mm this was a bit of a mistake.
With focused effort and training before hand, I have fit it a number of times and each time reminds of its power.
It is as smooth and inviting as it is dominating and addicting. With the widest part at the tip, once its in, it owns you. Each bump demands that you push it deeper until you finally feel the grooves at the base. Lemme tell ya, if there was a sound with only those grooves I doubt I'd ever be able to stop using it.
Highly recommended for those who can take 10mm, absolutely amazing in firm. For those who can't, probably get softer as this sound is fantastic.
