NCM Moscow+ from 3x8 to 1x10 and it is awesome!

I switched from the original 3x8 to 1x10 drivetrain and it is a fantastic change!

Less weight, less controls and cables, easier to drive and enough ratios!

You will need:
- a single chainring (narrow wide to keep the chain in its place safely, I never had a problem. I suggest a 32T but you can use 32,34,36... You can keep the shimano crankset or upgrade to something more specific. The shimano worked well but I decided to get something new :)
- new chain (10 speed)
- new shifter (I used shimano deore)
- new derailleur (i used shimano deore m6000)
- new freewheel (the best option is the sunrace 11-36, because it is the only with a 36t sprocket, but you can go with the dnp 11-34 if it is enough for you, cheaper and easier to fit). The sunrace 11-36 is a tight fit and you will need to add a spacer to the right side to get some clearance from the frame and 2mm spacer between the motor and the freewheel because of the shape of the sunrace freewheel.
- I also replaced the last section of the hose cable for a better fit.

The picture is with the DNP 11-34, but I have recently replaced it with the sunrace 11-36 10speed

You could also keep a 1x8 configuration, but 11-32 is not enough for me because I do a lot of climbing. (there are however some 13-34t 8 speed freewheels out there)

If you need help on the procedure please let me know!

Interesting - you undid one of the things I liked about the Moscow - the large 48T chainring by putting a small 32T on there. So many bikes are low geared, so when you get up to higher speed, you're hamster wheeling. Of course, for the trails, you don't normally need something geared that high, but I considered it more for a dual purpose bike with a lot of rural riding. Anyway, dropped that idea after hearing about all the broken spokes on these.

Thanks for your comment ;)

The Moscow is a heavy bike and I do a lot of climbing and some downhill (I know this is not the best bike for that purposes) but I had a lot of fun and never broke a spoke (I check and tension them periodically). So I decided to have a simpler bike and save some weight and it did work perfectly!

I never miss the high speed chainrings... I do not need speed with this bike ;)

But this one thing I really like about this bike, it is very easy to customize for everyone needs :D

I see. Well, probably a good idea to keep some spare spokes on hand just in case.

Do you no longer have the Giant mountain bikes and decided to settle on a Moscow?

I'll probably buy a second e-bike for next summer (2021), and the Moscow / Moscow Plus is still in the running. If I was going to do much mountain biking, though, I would buy a mid-drive, possibly full suspension. I'm not sure I'll do enough of that to justify spending the dough.

Hi!

I have both bikes (giant fathom e+2 pro and the moscow plus). Both are rigids bike because we usually use them with our kids (3 years old) with baby seats installed. The moscow+ is the bike of my wife. I installed a suntour seatpost suspension on both and they work fantastic. I will buy a full suspension once our kids won't fit in the baby seats (next year).

I really liked the single chainring on my giant so I decided to do the conversion for the moscow and my wife likes it a lot too. The moscow with the baby seat and the kid is too heavy so any weight gain is very wellcomed.

Cheers!

The 1x8 conversion is almost free, you just need to buy a narrow wide single chainring and install it on the current crankset removing the 3 original chainrings (10€)

The 1x10 depends on the components you choose. I chose shimano original components and sunrace cassette which are more expensive. I also upgraded the crankset, but it was not really needed. My costs were:

- Upgraded crankset: 20€ (cheap one from decathlon)
- Sunrace cassette (11-36t 10speed): 60€ (You can get a dnp 11-34 for 25€)
- 10 speed Chain: 10€
- Deore 10 speed derailleur m6000: 45€
- Deore shifter: 20€
- Motsuv narrow wide 32t oval chainring: 10€
- 2mm spacer for sunrace cassette (not needed for dnp): 10€

If you use low cost products (from aliexpress) you can save 50% of all the costs and they should work more or less the same. The only thing is that if you need a 36 cog, the only option is the expensive sunrace cassette.
