Does not fit

I guess my Brooks B17 is a little too old for this spanner. Afraid it does not fit.

ConsCostly for a spanner
ProsMakes a nice key ring
This the best tool for getting the tension right on most Books (some use a 4mm hex) . An open end 13mm will not work , I tried there is not enough clearance between the rails .

ConsExpensive for small spanner
ProsFits perfect
The shape and design of this tool is perfect for adjusting your saddle. You could buy similar or cheaper but this is designed by brooks for brooks.
Nice To Have

I recommend this product
This is one of those nice to have items, perhaps not essential as an open end spanner would probably fit into the available space, but it does however fit onto the nut easily, and allows more movement then a normal open ender would.

How not to lose it? Perhaps use it as a keyring for your bike lock?

ConsPerhaps a little expensive
ProsLooks like a spanner, I guess it will be perfect for the job
Bought this because I thought, 'well why not'. Looking forward to using and hoping I won't lose it before I get the chance. Time will tell on this one.
Best rim tape

This is the best rim tape unless you need thinner tape for tight fitting tyres.I found Continental rim tape good for that.
