The Deck model 1 features a conical Helleberg style cup, a .323- (8.2MM) bore, and 32.6mm I.D. rim. 33.2mm and 33.5mm I.D. rim options are available. The #1 rim is identical to the #3.
The #1 may be ordered with a larger bore if you wish or it can be bored out sometime later if you would like slightly less resistance.
