You might have to pry the Raleigh axle loose from its moorings in the fork tips. I know that when I've worked on them (had three Sportses and am now down to two) it seems like they sometimes hang up on removal. Approach from the front and remove the axle nuts, then invert your hands and wrap your fingers around the lower parts of the fork blades at the curve with your thumbs on the axle ends and see if you can pry things loose. Might need the proverbial Bigger Hammer or a pry bar. It'll come out.

Adding that speedo drive will make things even tighter when you put it back together, so get your best words ready.

Yea, very hard to remove wheel. Hoping I never get a flat on a hot miserable day!!! Would be using EXTREME words and would
probably go into crazy mode and destroy the bike!! I might just not use the speedo and save my sanity by leaving the wheel alone.
Thanks!

Those Raleigh ft hubs and drop outs have a less common design which make mounting this type of spedo drive problematic.

First is that the cones butt right up against the drop out inner face with no locknuts, the outer axle nuts do double duty as both wheel securing and bearing cone lock nuts. Knowing this will avoid crushed or loose bearings in the future. Do your homework here.

Second is that without a cone locknut each time the ft wheel is removed the spedo drive unit will come loose. The "right" way to install this is between a cone and a locknut, trapping the drive unit in place (and the cable is unscrewed from the drive unit when the wheel is removed).

Third is that the fork blade end often will contact the drive unit and cause it to cock and not spin with minimal friction. Over time this will wear the soft metal that these low cost units are made of.

The last thing has nothing to do with the mounting but that these spedos are never spot on. Or even close. I had a few when I was a kid, back in the late 1960s. There's a hill near where I grew up that my Stewart Wagner 26" spedo would register near 50mph as I descended on my Huffy Mk10 (26x1 3/8" tires). Years later with a SKY tire drive spedo I "saw" about 35mph at full tilt. Being stronger and on a bike with 27x 1 1/4 tires anyone would have thought even more speed was to be expected. later with my earlier electronic "computers" which had a tire circumference setting ability I saw closer to 30mph typically. I was even stronger, heavier and by then riding sew ups. Andy (who still goes that fast in his dreams)

I have this mental picture of you on the sofa, asleep, with your legs peddling.

I remember seeing dogs lying asleep and then seeing their little paws zooming around as they chased the squirrel in there sleep. I guess we can be happy for dreams: I still scream on my (now gone) Paramount in MY dreams. You zip on your bike in your dreams. And the dogs - the dogs catch the squirrel I guess. But only in dreams. Sigh.

My feet cramp up when I sleep, others might see this as me dreaming of riding. I see it as old age. Andy

Or, for less than $7 (hint, I bought one on a lark) you can get this...works great. A little modern with the old...does the same as my uber expensive older Cateye wireless on my other bike.
