no they will not......
the axle fits perfect but the pin is too small at the bone end.
currantly, there are no other brand driveshafts that come as STD with the correct pin size.
for long time HB runners we have a method of fitting 44mm driveshafts at the front, its not too tricky to do but it does mean you can run the driveshafts from the older HB cyclones.
you need the "old" spool (the wider one) and you can get the spool cups and machine (or dremel) the inner lip completely off, this allows it to fit in the TCX with only a tiny bit of shimming. the extra width allows the use of 44mm HB driveshafts with no chance of them coming out.
i hope this is of some use to any other drivers who may be struggling due to the lack of parts that seems to be around the world at the moment.
any questions feel free.
