I need a new back wheel for my Triban 500 SE

[princeperch]

The bike is at my parents place.

When I next go next I want to change over the back wheel as the current one is massively out of true and can't be repaired.

It had new rear cogs and a new chain 2 year ago.

So I need to buy a suitable new rear wheel and swap the chain and rear cogs over.

Problem is I am getting conflicting info from the Internet about whether the bike has a freewheel or a casette which obviously makes a difference to the wheel I am going to buy.

Taking a punt does anyone here have this bike and do you know ? I can't find the original spec online but there is an article which mentions it has a casette, that should be good enough for me to assume it has a casette and not a freewheel right ?

"Every other way the triple (30/39/50) crankset and close ratio eight speed cassette are very welcome on a bike that's going to be bought by a lot of people who need help on the hills. Our very early sample had a Prowheel Ounce chainset, but Decathlon have now specced a Shimano Claris unit and the first 1,000 bikes will have a Sora chainset because of delays getting hold of the Claris chainsets"

Any thoughts much appreciated.

your bike will have both freewheel and cassette, they are two different things.

I'm assuming your word "rear cog" refers to the cassette which fits onto the freewheel.

You need to buy a rear wheel that has the correct axle for your frame and the correctly sized freewheel to match your cassette.

Start here and if you struggle take your bike to your LBS

I have that bike

Anything that takes Shimano cassettes which is at least 8 speed and uses quick release will be fine. If you get a 10+ speed wheel it will likely come with a spacer to fit a 7/8/9 speed cassette.

Cheers both.

So after compactly failing to notice the wheel I ordered off amazon (which arrived today) was not quick release (slow hand clap for me) I need to try again.

This looks like very good value to me. If my bike has an 8 speed cassette the back wheel should work, right ?

Thanks again for helping an idiot out...

That looks like a screw on freewheel type, are you sure yours is freewheel or the newer freehub type? both can be 8 speed, but the cassettes are different.

All I know is it has a cassette that goes onto the wheel as I had it changed 18 to 24 months ago when the chain was skipping. The bike is fairly new from 2018 I think.

If it takes a cassette then the above is suitable rather than the other one I posted earlier?

It all seems quite complicated!

[anonymous-user]

Can't be sure without seeing a pic. Being a 2018, I would think it's likely the later one, but if it's not, you'll need another cassette then. probably about £20-25.

The wheels look good value, but not sure they'll last long at that price. Notice they had a shimano alternative if it's just rear only you need

You would also need a chain whip and lockring tool for removal of your old cassette

Most modern (non disc brake) road bikes are 130mm rear axles, but again without checking can't be sure. You could end up with another spare wheel!

The wheels that came on the Triban were cheap and mine didn't last long.

Replacing them with another cheap set doesn't make sense. Better to spend the money on decent wheels that will last.

They use the standard wheel size so I wouldn't worry about that.

It really isn't complicated.

Buy Shimano compatible wheel
Take old cassette off with chain whip and cassette tool
Put spacer on new wheel hub
Screw cassette on new wheel with only light torque (or you'll never get it off again)

If it is non disc brake it will be 130mm spacing, disc brake will be 135mm

Loads of wheels available to suit, as above I would buy a better set if possible

35nm is the torque setting for Shimano cassette lock rings.

That’s not ‘light’.

It's lighter than than screwing it in till you can no longer turn it. Which is what people tend to do with bolts.

Plus it's easier to tighten it up a bit if it's a bit too loose, than go through the pain of getting a stuck cassette off.

Or just get a torque wrench . . .
