Got a specialized rockhopper m4 yesterday ,need to remove cranks as chainwheel side pedal threads crossed.
Hollow axle ???
so conventional extractor no good.
which tool do i need ?
If it's an ISIS/Octalink BB you just need to put a 5p across the hole and use the standard connector (or get an ISIS compatible tool).
I've assumed it's a conventional axle BB.
Conventional in octalink ,yes n hollow axle .
will have to use a 5 cent as in eire,are they as strong as 5p .?
Thanks will give a go .
use two 🙂
as long as they fit down the threaded part of the crank arm and rest securely on the outside of the axle you should be fine.
Success after trying combination of 1 cent pieces ,they do bend nicely around end of extractor,now got nice copper end molded around it now ,looks quite cool 🙂
needless to say it was reluctant to to be extracted.
may look at different BB now with new crankset,time to search e-bay
