Ontworpen om strak tussen de zuigers of remblokken van de schijfremklauw te passen, waardoor beweging van de remblokken naar binnen wordt voorkomen.
Took a few tries to get it seated just right between the SRAM Guide pistons, but once it’s in, it holds them perfectly still during pad swaps. Solid little block for the price, though I wish it came with a handle or pull tab for easier removal.
It does the job of holding the pistons still, and the snug fit in my Guide calipers is fine for a slow bleed. That said, getting it placed right takes a bit of fiddling, and it feels a little flimsy for the price. Works, but nothing special.
