Changing tube on a single speed with mudguards

symo

OK

MY bike has a puncture.


So how do I remove the rear wheel on the bloody thing, do I really have to take the mudguard off to change the tube everytime I have a puncture.?????

Also the chain needs to be removed to extract the rear wheel which has a strange link which I assume has to be prised open to take off, anyone know of a good photo guide on the internet for that??

Push the link left to right in the picture.

re the wheel no ida as there is no image of the drop outs.

but maybe.

Can you turn the cranks forward and push the chain off the ring at the front with your thumb to give you the slack you need to get the wheel out without breaking the chain? That's what I do. WARNING - Watch those fingers!!!

Alternatively push the wheel right forwards in the dropouts and then you should be able to bring the chain off relatively easily without splitting it.

As for the mudguards, you can get a part (from SJS IIRC) that allows you to snap them on and off easily for this.

I often change punctures without taking the wheel off. The only reason to take the wheel off is if I have to change the tyre like I did this morning or if inner tube is beyond repair.

With a SS you need to set it up so that breaking chain is not needed to take the wheel out.

Should be possible to push wheel forwards in drop outs and un-hook chain from cog, then do the reverse when putting wheel back in. If not then your chain is set too short.

To do this need to ensure that axle is no less than half way along drop outs when chain is tensioned.

Any less and you may not have enough slack to play with in the chain.

Below is a tip for getting chain tight and wheel centred, it is much better than just pulling back on the wheel and tightening up nuts.

- pull back on wheel so that wheel is centred and chain = tight.
- tighten drive side axle nut
- now push wheel towards non drive side as far as it will go, using the axle as pivot and wheel as lever to tighten chain
- tighten non drive side axle nut
- loosen drive side nut
- push wheel towards drive side
- tighten drive side axle nut

wheel should now be centred & chain tight. if not repeat above steps until it is.

Being Dutch, this is how you get taught at primary school.

- turn bike upside down
-take tyre levers out and flip one side of the tyre over
- undo valvle cap and llocknut
-squeeze innerube out
-inflate innertube a little and find puncture > fix puncture
- check outer tube for debri (run fingers on the inside).
- put everything back in place
-inflate and ride.
- only need to get the wheel out for replacement of tube or tyre; not for fixing a flat.
-should take about 10-15 minutes max.

Forgot to say done and thanks for all the advice. Tried the Dutch method and couldn't do it. So wound the small allen screw things at the drop out to the point where they were bearly in the horizontal drop out and then managed to slip the chain off and then reversed the whol process.

Nothing particularly Dutch about that method, it is simply Old School from when we all rode three speeds and didn't carry spare tubes, just a big pump and a puncture kit. Mind you its not that great when it is raining and you can't find any shelter, patches wont stick to wet inner tubes unfortunately :?

no, just take it off once and keep it off.
