Repair the bike or buy a new bike?

Gives you an overview. All these pedals will fit the cranks you have currently. All you need to remove the current ones and fit any new ones is an allen key (or possibly a spanner 15/16/17mm).
I'd recommend spd pedals (probably clip one side, flat the other is best) and shoes with the simple spd metal cleat too.

Are those shoes and pedals compatible?

Is there much difference between SPD and SPD SL pedals?

Yes, they’re compatible. Do you need to spend £160 on the shoes though??

Difference between the pedal systems in terms of...?

LJ you really need a cycling buddy to show you the ropes. Isn't there a local club you can join? You may not be able to ride with them yet but there may be somebody who is prepared to meet you at a distance somewhere like a park and chat about these things.

Perhaps not, but I like the look of those pair of shoes.

I’m going to order a pair of shoes and clipless pedals sometime during the weekend so they will have arrived by the time the bike has been sorted.

Here's a beginners video for clipless pedals.



As mentioned, you do no need clipless pedals to ride your bike. If you do want them, you can choose. I used both SPD and SPD-SL on road bikes. I prefer SPD-SL. I just prefer the feeling of them when sprinting/getting out of the saddle.

The shoes are serious overkill but, that's entirely your money and choice.

The SPD-SL pedals you have linked are very decent and you can keep them should you decide to sell/upgrade the current bike.

Fair enough, depending on which colour they could be £200
Tredz don’t do free returns either I think , so if they don’t fit, it’ll cost you in postage (normally around £7 for shoes but you’ll want extra insurance given the value). Normally I’d suggest getting two pairs and returning one but not given the cost of the shoes and the postings.

You could risk Asda option I guess

see if Sigma have the shoes as they do free returns

Is it possible to buy an old bike from the 1980s or 1990s e.g. an old Raleigh road bike for about £100-200 from eBay and put new stuff on it? Or, are the older bikes not compatible with clipless pedals and a new derailleur, etc?

be careful with this approach! A dark path it will lead you to.

Raleigh, being one of the biggest manufacturers made EVERYTHING in house and so were still working to their own sizing, spacing and even screw threads until around the 1980's, as such compatibility can be an issue.

I have two road bikes, both Carlton which were built by Raleigh. The wheels are a different size, the hubs a different width and a few other quirks, but lovely bikes.
I do have modern pedals and derailleur on them though.

Coming back to the original question,
The bike originally cost £350-ish you say, so unless you're paying just short of that for repairs you're not in new bike territory yet as you'd likely be replacing it with something that has issues to fix (might be small issues) or something that the parts aren't quite as good and may wear out and need replacing.

I think the only original thing on one of my bikes might be a quick release bolt!

Most things can be fixed with time, patience and a few cups of tea and taking each problem on it's own makes it simpler.

I learnt pretty much everything from here: https://www.sheldonbrown.com/repairs.html
And having a good, and helpful bike shop who could sort out things I'd not managed to do!

Regarding SPD v SPD-SL clip system difference, did you read the link I offered earlier? If so, try answering the question yourself.

I would recommend you do not use Tredz and that you buy entry level SPD-SL pedals (if you choose that option).

Note that white pedals (you linked to) will look odd on the red bike.
Most pedals will come without cleats: check this (and buy cleats in addition if necessary).
Even if you 'like the look of those shoes' I fear the red shade on those Sidi shoes will clash with the frame of your brother's bike: please take that fully into account
Take care with road shoe sizing.
I agree with @Globalti. Find someone local who has a road bike and invite them to share their knowledge.
Beware of the trap of becoming someone with 'all the gear and no idea'.

I neglected to say in my earlier post, I'm using Decathlon shoes and clipless pedals, the road type and my wife using Decathlon's copy of Shimano's mountain bike SPD pedals, shoes and cleats.

Sitrep: OP has taken the bike in and the mechanic has said: 'cos of Covid I can't get spokes and other parts [Comment: what other parts - a gear cable?]. I can have it ready in 13 days!!!!
I've suggested to the OP he retrieves his (brother's) bike and tries another LBS. Maybe Halfords becomes attractive in comparison with the loser he went to first.

 

[vickster]

I’m guessing the (Presumably) shop owner who spoke to the OP didn’t check with his mechanic before booking in

 

[DSK]

Blimey, I see in in 2 ways.

Either the shop does not carry stock or, they have been overwhelmed with so many cases such as the OP that they have genuinely run out o stock of basic consumables.

I know my local full time 1 man band has been upto his neck in bikes since lock down with everyone getting their BSOs out and the usual regular cyclists doing their annual stuff of upgrades and servicing.

No LBS purporting to provide a repair and maintenance service can reasonably 'run out of' cables, outers, spokes (various lengths), oil, grease, loose bearings, brake blocks for rim brakes (at least one option for each kind). If we punters can get these, then certainly bike shops can. I can only assume that the LBS mechanic has identified all sorts of other 'parts' that she'll need to get the bike back into working order.

I would expect some detail on what is needed if that was the case.

agreed we can (and I have been) get supplies of all types as needed without issue from the mail order giants.
