right i thought i knew most stuff about bikes. just bought a new stem for the trials bike. nice onza one, big reach and rise as its a 20" mod bike. so stem turns up. try a 25.4mm bar. too small. right so ordered a lovely 31.8 megamo flattie. too big. wtf! what size is between 25.4 and 31.8 :?
 
got any verniers about?
im not sure why but i have 28.8 in my head? :?

maybe try some motorbike handlebars if you got any about?
 
In what way is to big the front plate and the stem shuldn't be touching when done up tight. Maybe 2-3mm of bolt between the two parts (rough estimation).

Maybe post a picture of how it dosen't fit.
 
its a non removeable face plate. there is about a big gap around the 25.4 h/bar and the 31.8 doesn't get anyway near.

28.6 is motorbike sizing, but there is no way i'm forking 50 notes for a vegas bar for this heap :LOL:
 
thanks for that. thought i was going mad :LOL:

just ordered an aluminium seat post shim which should do the job.

thanks chaps, every day's a school day
