20" UDC Penny Farthing Rim - 28 Hole
The UDC Penny Farthing Rim is a high quality deep section rim that is produced especially for the UDC Penny Farthing or you supersize Unicycle.
This rim is described 20" but a standard 20" tyre will NOT fit on this rim.
This is the rim that comes with our UDC Penny Farthings. We generally fit the 16" Standard Highwheels Type #1 Penny Farthing tyre which makes the wheel diameter just under 18" (it is a tight fit but it does go on). Some solid 18" tyres may fit but it is best to check all the dimentions before ordering. If you are still unsure please feel free to contact us by E-mail, Livechat or give us a call.
