Conversion to single speed

gixer5

I have a 90's raleigh summit which is currently sat in the shed not doing anything. I would like to convert it from a 21 speed Mtb into a single speed commuter but I'm not sure what I can keep / adapt or what I need to buy in order to carry out the conversion. Can anyone recommend and websites or give me any advice on what I need to covert to the world of single speeding?

ive recentlyish done this on an old bike for the school run,
spacing wise out back, pop to your lbs and see if they have any Scrap old cassettes, ideally 3 as you'll need to split them for the plastic spacers, (a packet of chocolate biscuits is often appreciated for such items!! ;-) ) you casn also use one of the cogs for the basck too,
single chain ring up front obviously,
for a tensioner ive used an old mech, chopped the jockeywheel cage off just under the top pulley and run the chain under the cog! then just a chain that fits,
i started mine off on 32/16 and quickly swapped the back out for a 14, ive used it around the village and its fine, occasionally put the littluns trailer on it, ideal as a round the village hack bike instead of the Soul!!!

if you want a Proper Kit for doing it then have a look on either superstar or On one,

thinking about it, being a 90's bike May have a screw on freewheel rather than a std. cassette body as we use now, if so, then a std bmx/kids bike freewheel cog will do it!!
