Hi Emma,
of course I’m always sorry to hear something like that and also I’m sad every time that I can’t tell much more than this:
Please consider that your bike must be far over 20 years old and the replacement part manufacturing was cancelled already several (if not many) years ago.
Regarding the Strida EVO kit I’ve noticed the following at a first, quick sight:
- Seems that the EVO kit does not include a wheel, so you had to add the costs for at least one wheel, freewheel, rotor and caliper.

You meant that one?
Question in between:
Does your Strida have drum brakes?
If yes - then you need another seat tube too, because a drum version does not support disc brake calipers.
My personal experience in ancient bikes is unfortunately very limited, I’m familiar with versions from 5.0 upwards only.
Cheers,
Chris
