Need advice on how to fix up a bike

[Drencrom]

Hi guys got a free bike and stuck already on taking it apart.

I'm struggling to remove the bolt on the Shimano Tourney gear mechanism and I'm not even sure if I should be removing this bolt?

Is there another way that I've missed to take it apart?


I've got Allen keys and they don't fit. What size shall I order or is this bolt not made for an Allen key?

It seems you can get a brand new rear mech for about £14, so you need to balance the cost against the effort needed to dismantle and renovate.

New chain, cables, brake shoes and cassette as well, should give a good facelift to the bike.

Guessing £50 - £70 should be needed for this, so need to consider how much the end product will be worth to you.

That's sounds about right. I'm looking to spend £100 and £30 of that will be a new seat.

Is it that Muddy Fox MTB? You can get one in working order for £25.

You might find that somebody on here will have a saddle in their "parts" bin for a few pennies.

Normally you wouldn’t remove that bolt on a Tourney derailleur, standard practice at the shop would be to take the chain off instead. You’ll want to be doing this anyway to replace the rusty little bugger ( or at least give it a proper clean and soaking )

Tourney derailleurs, although total crap to a bike snob, are pretty bulletproof proof and will work acceptably well if anywhere near straight. If they aren’t straight they can take some horrible abuse if you want to just pull it straight gorilla style. Don’t bother with the ‘B’ adjustment screw, they do absolutely nothing even when new.

When reinstalling the chain make sure you route it through the cage properly, watching the little cross tabs, run the chain outside of one of these and you’ll have no end of weird shifting and grinding noises…. Although I’ve seen them work anyway.

Although it’s a cheap, cheerful and reliable piece of hardware Shimano really could do better for no more cost and should therefore be ashamed of themselves for continuing to sell this thing.

although not nearly as ashamed as they should be for Cues. No excuse there as it’s not as good as the stuff it replaced.

You said in the other thread £30 on a comfy seat. If it’s something with padding you might be disappointed.
