do you happen to know a site that has like 15 days and less of delivery that ships to canada?
also i notices some have

SGS written in there name

With your derailleur hanger, you'd need the direct mount version of the derailleur, not the claw or reverse claw. As for SGS, Shimano has three ranges of rear derailleur cage - SS is short, GS is medium, and SGS is long. This matters for some derailleurs that are sold in multiple variants. It looks like the RD-TZ500 derailleur exists in GS and SGS versions, but the RD-TY500 appears to be SGS only (though I could be wrong).

I wonder thought whether the specs I previously saw for the yorkville are what you actually have. Is this your actual bike?

https://www.norco.com/bikes/2021/cit...lle-step-thru/

I just noticed the specs seem mixed up. The page for the yorkville (non step-thru) list the rear shifter as RD-TY500, but this is a rear derailleur part number, not a shifter. Both pages list the rear derailleur as the RD-M360, which is a higher grade part than the RD-TY500 derailleur I previously thought you had. Either derailleur would work fine, but if you could find it, I would get the RD-M360, or even RD-M390 as I suggested before. I think these are available in both GS and SGS versions so be sure to get the long-cage SGS for your 34t freewheel. But if you feel safer with the RD-TY500 since it explicitly says its for 6/7 speed, that should work fine.

The shifters are a bit of an open question. The yorkville's page lists the Tourney EZ-Fire ST-EF500 as the front shifter, while the step-thru page lists the Altus Rapidfire ST-M310 for both shifters.

https://bike.shimano.com/en-EU/produ...F500-7R4A.html

Either way, these are combined brake lever/shifters, so if you were to go with any of the levers I previously listed, you'll likely have to deal with replacing the brake lever too.

Fortunately, there appears to be a nice answer here. There's a 6-speed version of the tourney EZ Fire Plus shifter, the ST-EF41-6. This would replace your existing brake/shift lever. I didn't know EZ-Fire Plus existed in 6-speed (it's like Rapidfire, I don't know what's different). It turns out too that the SL-TX shifters I cited before, are fancier than I'd realized, having a a push lever for downshifts as I'd presumed, but also a push button for upshifts.

You might still consider separate brake levers though - they give you more flexibility in adjusting their positions independently, but if you're happy with your existing brake/shift levers, the EZ-Fire levers can't be too bad.

As for where to buy in Canada, searching from here in the US, all I could find seem to ship from overseas. You might have better luck searching for yourself.

Here's a few Canadian listings for the shifter:

https://www.crankys.ca/product/shima...r-374393-1.htm


For the rear derailleur, you can probably get one, or an equivalent, at a local bike shop. The shifter is a less common item which they're less likely to have, but it wouldn't hurt to ask: they may be able to order it for you.

Oh, ones last thing to be aware of. I think the spec sheets for the yorkville indicate it comes with 4-finger brake levers. The ST-EF41 is a 2-lever brake lever. Not necessarily a big deal - there seems to be more discussion around braking with 1 vs 2 fingers than there is 2 vs 4 - just don't be surprised by the change if/when you swap your levers.

##does direct mount means donut form and claw means c shape?

### yes im pretty sure it is this on. it has probably more than 12 years .

## having a motor on i purchased a pair of electric brake lever that cut electricity when pushed so it cannot be combine.

humm would you say that sgs long cage is more important than oversized pulley? that is what i understand from the previous posts.
