Hi all
I need to get a sprocket off (but also must be able to re-use it) so that I can strip and clean a wheel. I remember the days of using a socket with nipples, or if in dire straights a screwdriver and hammer :'(, however I need to be able to re-use this sprocket and don't want to damage it in any way.
I have no tools like this anymore.
The sprocket that has 2 small holes, centre to centre is 4 cms.
Can I use a Chain Whip? or do I need a socket?
Any help please ASAP.
Thanks

You need a sprocket removal tool. Biagio has them, and they're always on the bay. :daumenhoch:

if you need it fast, go to your local bike shop and buy one, or get him to do it if you are a novice ;)

Hi all
I have searched the bay and also visited a few shops, but they have dozens and nothing that fits.
The only way to get it off is by using the spanner with 2 small circular prongs 4cm apart, there is no other recesses etc.
Apparentley this sprocket is rather old (so that's a good thing for the bike), but I don't know how to get it off unless I have a tool especially made up.
Any help? or i'll have to get a tool made by an engineering company :'(
Pics tomorrow
Cheers

1- freewhell in the vice
2- Tighten the feck out of it and crush it.
3- Twist wheel so the freewheel comes off
4- Buy a new one :)

Hehehehe
This is a totally original bike :'(
It is mint and was gonna be at the show n shine as a totally original specimen.
It is a real peach but I don't want to damage anything or replace any items. Buying is too easy. The chain took me hours to clean and so far I have spent 30+ hours and £0.00
Am I mad???

Hi all.
So I live near Cambridge, have spent two days driving around various towns trying to buy a tool, or find a cycle shop that has a tool to get this sprocket off, and getting pretty pi$$ed off in the process about such a simple problem.
I have tried most local towns and with Cambridge having dozens of cycle shops and after visiting most of them, I thought that i'd try Halfords, but was sure that they would be a wasted journey.
So, in I walk with this dirty rusty old wheel as young kids ride / sit on new shinny bikes as parents check price tags, and I explained the situation to a young-ish lad who thought I was mad and had no ideas......
But after a good chat and explaining again how this freewheel works to another chap the freewheel came off without any damage. :) and during this time we spoke about BMX, it's bizarre how things happen!
Anyway, he also rode BMX in the early 80's on a Curtis, did quite well, and I'd like to say thanks to Shaun Pearce.
So, if any of you know / remember him, we hopefully will have another old rider back onboard soon as he has the Rad details.
