At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Shimano's TL-SR22 (catchy name) is a workshop quality bit of kit for getting your fixed sprocket super-tight. With an over-engineered lockring spanner and a heavy-duty chainwhip it'll cope with any 1/8" or 3/32" sprocket.
This tool is a heavy duty bit of kit: you won't want to carry it around with you, but if you like to chop and change ratios on your fixed or track bike then it'll pay for itself soon enough. Well, quite soon anyway. £40 is a fair whack for a spanner but a threaded sprocket is something you really, really want to get properly tight as anyone who's ever pitched themselves over the bars after a slipped cog – me, for example – will confirm.
The lockring tool is capable of some serious torque, and you'll need to be careful with Aluminium lockrings as it's fairly easy to cut a chunk out if you go too hard with the big rubberised handle. The chain whip has five links of sturdy 1/8" chain and a separate link to hold the sprocket nice and firmly; it'll work with 3/32" cogs too although you'll need to take a bit more care.
If fixed or track riding is a big part of your life then you'll not find a sturdier sprocket tool than this. A workshop staple and once-only purchase.
