Bikehut cone spanners
 

Oh dear. I needed a 17mm wrench for my idiotically-designed XT hubs,
which no longer take an adjustable spanner or, in fact, any normal
spanner for the locknut - it has to be a thin cone spanner - and
H*lfords had sold out of Park stuff so it was the Bikehut ones (actually
made for Cyclo in the Far East).

They are paper-thin and they flex so the spanner pops straight off the
locknut with any application of torque. They're going back tomorrow and
I *really* needed to do those hubs tonight. Why is everything I buy crap?
