very light grinding noise from the back wheel

[Veganpower]

Hi all,

I'm a little concerned about my Triban 5a. After a 50km ride I noticed a light grinding noise from the back wheel. I went back to Decathlon today but the guy there wasn't a mechanic.

I'm new to bike repairs, is this common? any suggestions on where I should start?

Sounds like the bearings need a clean and lots of grease

If it's new bike, check the rear derailleur cable tension. Likelihood is that your gears aren't aligned properly

If it's a Triban, replace the wheel bearings. The original ones are carp. It's the Triban's achilles heel, but is fine with new balls. Your LBS (it's not difficult to do at home either) should be able to do this and I'd recommend asap before the cones and cups get pitted. Once done they'll be fine.

It's a brand new bike guys, although OP has not stated that in this thread!

So was my son's Triban with the same issues ....

could be brakes.....? release them completely and check it isnt that

A replacement front wheel for Triban is £25, which explains why they are actually made of cheese, not metal.

thank for the help. I suspect it is the bearings because that is where the noise is coming from. I remember seeing a rear wheel on the bargin thread. Perhaps It would be easier to just buy a new wheel?

I'll go back to Decathlon first though. As uclown mentioned, its an new bike. Done 117km.

You'd do better to flog the wheels on Eblag and treat that otherwise nice Triban to some entry-level Shimano wheels costing around £100.

my Triban had the same issue - i packed them b'stds with grease and all was good.

GOD i miss that bike

I did put some RS10's on her and she rode as well as my Defy which cost 3 times as much.
Only sold as i wasn't using her enough :-(

They do handle very nicely.

If you have the tools it'll cost you a few quid to put new ball bearings and pack 'em in grease or Vaseline. It's a useful skill to learn.

If you have the cash, globalti's plan is good and with better tyres will really transform the feel of an already good steed.

Oh yes, the BTwin tyres are terrible. Treat it to something good like Michelin Pro 4s, you can get them for £21 each if you shop around. Beware though - BTwin tyres have a low profile and with a slightly deeper tyre you'll suddenly find that the rear wheel comes up against the chainstay bridge and doesn't have enough space to move forward for the QR to clear the RD dropout when you're removing it, which makes wheel removal slightly awkward.

I dont suppose the Tribans wheels are any different, every budget (cheap) wheel i ever brought had to be adjusted properly straight away.
Cheap alloy wheels for my hybrid, really cheap, were poorly adjusted and 'grindy' striaght out the box. Strip, adjust, grease...theyve run for a few years no problem.
Cheap wheels arent neccessaily total crud, set up properly, they will perform ok .
