The OEM stuff is actually metric tubing (4mm, I think) it is slightly larger and thicker than most 1/8" stuff. I'd like to find a place that sells the metric stuff by the spool at a bulk price.

I'm using the 1/8" tubing with no issues on one bike.

Here in Hungary very difficult to find anything which measured in "inch" (ok, only the water pipes:smirk:).

Every tube and screws and everything in metric.:smirk:

yup but who uses metric anymore? its a thing of the past...

It is not a "past" or "future" question:)

check what is an official (SI) unit of length (meter, and 1m=1000mm). You can believe use inch for checking something is difficult (have to calculate always and not spontaneous) here, as you for use metric instead of inch.

Same situation as use mph instead of km/h.

this is a forum from the USA, therefore no question furthermore:thumbsup:
