Raleigh Chopper Mk2 Rim and number of spokes

[JonathanGunn]

Hi there. I am rebuilding a Mk2 Raleigh Chopper. I bought a 28 spoke Sturmey Archer hub and have been struggling to find a 28 spoke rim to fit it. It seems as though most Choppers had 36 spokes. What is the correct hub size and are 28 spoke rims available ? Thanx

28H (spoke) rims are available in a number of sizes; what size are you looking for?

Without pictures, we have no idea what you bike looks like, nor the original equipment. Do you have link to a catalog page or spec sheet?

I think the Raleigh chopper had 16" front wheel and 20" back wheel. Raleigh often used 28 spokes on the front wheel, and 36 in the back wheel, which (again) I think was standard on the MKI and II choppers. Chromed steel rims were common too. The standard AW 3 speed hub came either with axle 146 mm or 163 mm, including threading for the nuts and washers. Good wheels can fairly easily be found on ebay, at least ebay.uk.

is the 20": 451, 419 or 406 ? http://sheldonbrown.com/tire-sizing.html#iso
349 seems to be the only choice for 16"

Sun offers the CR18 rim in 349, 406, 451

here is a 28H 406: http://www.amazon.com/CR-18-Shrader-Valve-Black-22-2mm/dp/B001CJXBWW/

and a 36H 451: http://www.amazon.com/Sun-Alloy-CR18-Silver-Satin/dp/B000AO7EX2/

On a very worn old tire I can make out 20 x 2 125, but not much else.

that should be a 406 per Sheldon's site; more specifically 54-406 tire.
