7 Speed to Singlespeed

excuse me being a complete novice,but i own a 7 speed chas roberts that i want to convert to singlespeed,the converter kits ive seen on CRC and on one only apply to 8 0r 9 speed wheels .can any of yousuggest a 7 speed version.

diy, grab some hub spacers and work on it.

or get a new hub.... they can make all things better.

what toothed sprocket would you recommend chris

Kits seem to come with 16/17T.
If you need to change you can get a new 'DX cog' for £4..

wheres the best place to buy sprockets and a spacer set "said the complete novice"

in london

Internet cafe?

can you recommend any shops in LONDON

problem is i own and maintain 6 bikes,but what i know about singlespeed or fixes you could write on the back of a postage stamp and still have enough room for the lords prayer

ask sheldon RIP your questions, he still knows all.

bricklane bikes will have ss/ fixed stuff all over.

and i lied in my frist post you dont want hub spaces you want cog/ cassete spacers these depend on your hub, so bring it in and talk to the mechanic

gearing really depnds on your riding style, distances, leg stranght, and lots of other stuff

i would segust that you strip off all the derailers, put the chain on the two middle rings, take out some links so its tight, and ride around a bit, then try different gear combinations till you find the magic one

thanks chris ill give what you said a try and sadly to say sheldon brown the greatest bike tinkerer of all time passed away about a month ago

does the rear hub take a screw on block or cassette?

cassette shimano

reculver thanks chris ill give what you said a try and sadly to say sheldon brown the greatest bike tinkerer of all time passed away about a month ago

That's why Chris said 'RIP'! :p

just bin on sheldons site ,found out that my zeus chainset on one of my bikes has 16mm BB bolts ,so ive got to angle grind down a 16mm socket so i can take the zueus off and put a nice campy GS one on it

I have some spare spacers (from dismantling old cassettes) if you want to use them instead of a specific kit?
You can then either choose which one cog from your cassette you want to use, or better get a DX cog, or even a better cog which is less likely to damage the aluminium freehub body...
there is a guy selling some bits from singletrackworld
If you buy a kit i'm not sure it will fit on a 7-speed cassette...?
Some kits consist of many smaller spacers rather than just 2 big ones (e.g. Gusset after link) and I'm sure you could get those to work more easily if any fettling is required.

thanks everybody,for all your help i was completely in the dark with this but with your knowledge and my bag of hammers im sure ill sort it

Er before you take to your bike with hammers, you could just take off the derailleur and pick the cog with the best chainline (which will probably be a decent gear for single-speeding with anyway. Cheapest (free) and quickest option.

i only mentioned my bag of hammers,cos where i live they wont let me have any sharp objects and this new jacket they gave me buckles all the way up the back .thanks again for the advice

You need one of the thin CNC type spacer kits - ebay search "cnc singlespeed spacer" :) - will work with any hub then or as above a bag of old cassette spacers. To find your ratio go out on your geared bike on your normal routes and stick to each gear for a loop or a few miles finding what suits you best - replicate that ratio in gear inches on your SS.
