Velocity rim (Australian) measurements needed..

On my Greenspeed GTO I have Stelvio 28-406 tires fitted on 32 hole Velocity rims. The front rims are the "Aeroheat" model with 32 spokes, while the rear are the "Taipan" model with 36 spokes.

Anyone have the (inside as with the Schwalbe tech manual) rim width?

I want to fit either Greenspeed Scorchers or Schwalbe Marathons to provide better wear (mileage) and better puncture protection than the Stelvios do, so I would need the tire widths to order....

Are the 32 hole rims OK for unsupported touring? I won't be near any bike shops if something goes wonky.

Thanks for any measurements.

According to https://www.velocitywheels.com/store/...?pID=79&cID=27 the outside width of the aeroheat is 24 mm, so a decent guesstimate would put the inside width at 19-21 mm.
The Taipan is listed as 28 mm, so an internal guesstimate of 23-25 mm
Sheldon brown has a page with recommend rim vs tire widths.

32H on 20" should be quite strong unless you go all crazy with your gear.

Thanks for taking the time to do the research. I found the Velocity Wheels website and sent them an e-mail with the specifics. They will give me their advice as to the inside rim width and the Schwalbe or Greenspeed tyres (!) to consider for the Perth-Sydney trip.

Svhwalbe has a tech manual with a LOT of info on tires. The pdf is a useful bit of data to save on the hard drive.

On, on :-)

I've worked with aeroheats before. The rims will support 23c+ tyres.

Aeroheat rims have a good rep.
