Overall Product Rating 4.6 / 5
1 Inch Spanner Required

ConsNot metric
ProsWell made. Guide pin helps keep tool in position
It takes a lot of force to tighten or loosen a cassette lockring, so I’d rather not use an adjustable spanner.
Unfortunately this tool needs a 1 inch spanner.
5 stars for SJS and their service.
4 stars for the tool generally. I highly recommend a cassette tool with a guide over one without
Zero stars for use of imperial measurements

Genuine product, exactly as ordered and at a sensible price.
SJS Cycles are excellent for workshop tools and hard-to-find parts & replacements for 'classic' & 'heritage' models, as well as the latest gear.
Thoroughly recommend their online / mailing service.
