Advice needed - B5 parts on a B4
 

Will a B5 or B5m front caster/steering block fit onto a B4 front arm?

Many thanks in advance for your advice.

Im pretty sure the hinge pins are a different diameter. I'll check later and get back to you if they are the same.

Thinking about it, the B4 fr axles wont fit the B5 steering blocks.

Thanks.

There's a complete set on ebay. Caster and hubs. Just fit and bolt on the (hex) wheels.

Thought it might add more options for me to get confused over.

In a short answer, no.
B4 is imperial, B5 is metric. However you could adapt it to fit. Why not just buy the B4 hubs with hexes if that's what you want?

Hi Mark,

I hate imperial screws.

I have the hex set up at the moment. Just when I saw this front caster blocks I wondered if it would fit with the hinge pins.


I've seen a few items, rear hubs etc, that say B4 and B4 so wondered if it would be ok to mix and match a few things.
