I have a Carrera Subway Limited edition 2014 with V brakes. The front gears don't shift any longer since I recently got caught in a lot of rain. I've been told by a cycle repair that I need to change the left shifter plus the front derailleur.

The original left 3 speed shifter, model is: Shimano ST-EF51-AL, isn't been sold any longer apparently and I cannot find it on the net.

Is there anyone that could suggest what left shifter could I buy instead that is compatible with this model?

    Bike shop's recommendation for shifter and front derailleur sounds fishy. One of the other would break, not both the same time. Also rain does not damage shifters. Perhaps you need a second opinion from different repair shop? Commented Aug 25, 2017 at 16:06
  • The cable sounds like it rusted internally. I agree with @ArgentiApparatus though, it sounds like you need a new shop that will just replace the derailleur cable and lubricate the shifter and derailleur.

  • I've added a stock image of this bike - apparently it was a BSO sold through Halfords and similar. They're perfectly rideable bikes, but the sub-200 pound pricetag means they're not high end. So be cautious about spending too much on replacing parts.

That's just a mountain Shimano triple flat bar shifter with a V-brake lever.

You can buy any left hand shifter which is marked for triples from the Shimano mountain lines: Tourney, Alivio, Acera, Altus, Deore. You may need a separate brake lever, which has to be sold for V-brakes and flat bars (it will look like the existing brake lever). Microshift also makes compatible ones, as does SRAM under their Attack! line. You can also use a friction shifter (cheapest option, eg. Sunrace SLM10).

As an example, you can use the Shimano Acera SL-M310 shifter combined with the Shimano Acera BL-M421 brake lever.

Go to your local bike shop, and they should have a ton of these parts on hand.
