Boardman bike making a sound.

[lydiaald]

Hi, my husband purchased the Boardman MTX 8.8 Mens Hybrid Bike. The gears didn’t all work on the bike so we had trim shifters fitted. Whilst this has sorted the issue for the most part it’s still making a noise when in the highest gear. Is there any solution to this? We thought trimming may solve this but it hasn’t. We did read if you put a grx rear derailleur on this may help? Does anyone have any experience with this bike and found a solution?
Thanks

Tbf they did come back this evening at 20:46. So give benefit of doubt and your pearls.

• Rear Derailleur: Shimano Deore 10 speed
• Front Derailleur: Shimano Tiagra FD-4700

Should the OP return ....

I think we need more info to solve this one.

Even with this info, it will be difficult without getting close in person.

Hope you fix it.

If the bike was bought from new they should go back to to the place that sold it, otherwise the warranty will be void.

What are "trim shifters"?

What are "trim shifters"?

Had heard of the expression before and Google confirms ....

Some road bikes will come equipped with a front derailleur that has a “trim” feature. The trim allows you to make small adjustments to the front derailleur that will eliminate chain rub, but not cause a full shift into another chain ring.

Allows minute adjustment of the front changer to stop chain rub. I don't think you can get them for the RD. Might as well go back to friction changers.

Sorry, yes, I'm familiar with the concept. I was rather wondering what the exact shifters were before and after the change, and how exactly the "not all the gears worked" manifested itself.

As others have said, the bike shop should have sorted this, and for sure whatever the original shifters were should have worked - Boardman is a reputable brand, and according to their website the bike comes with "Deore 2x10" shifters - of which there appear to be several variants so impossible to know what was on there to start with, or what there is now.

FWIW if noise only in "highest gear" (presumably big/little) my guess would be limit screw needs to be backed off slightly, either front or rear depending on where the noise is coming from, which we're not privy to.

This is bo11ocks @Sharky . Why do you think Google knows better than 'us'?
An FD does not control its movement "make small adjustments", the limit screws do what they're meant to (and this is the most likely tweak for the as yet unreturned OP). Clearly many FD shifters have a 'trim feature'.
I too would need to know what the OP means by "trim shifters" in an FD context obv. And along @roubaixtuesday 's enquiry line.
