I bought Mrs Geordie a nice set of Superstar CNC Nano Thru Pin pedals (here) which I attempted to fit today. However, there appears to be no flat sides to the ‘spindle’ which will allow me to use a spanner to tighten the pedal to the crank arm.
Am I missing something obvious (probably), or do I need a specific tool? The ‘spindle’ has a slightly oval cross-section, with no flat edges at all.
Cheers,
I bought the same padels a few months back and also found them lacking any way to engage a pedal spanner. In the end I had no choice but to use the 8mm allen key hole.
get some steel bar and file it into a hexagonal shape measuring 8mm across the flats. There is then a secret part on the end of the threaded bit you can use this home made tool with 😉
on the outside edge of the pedal (edge opposite the crank arm) you should find a cap that can be removed.
remove this and proceed to disassemble pedal until you are left with it completely in bits.
Take the axle and about half way along file two falts parellel to each other.
Using a 12″ adjustable spanner or large mole grips tighten the axle into the crank and re assemble pedal in situ as it were.
Once assembled you won’t be able to see the flats and they’ll look bob on kid.
Immerse them for a few weeks in a solution of salt water and mud until the bearings are suitably seized. Hey presto, the spindle will now rotate when you turn the pedal, allowing easy tool free installation.
