[Closed] Looking for a 165mm crankset and a 30t nw chainring

Have you checked spa cycles and SJS?

Seems like there's less choice these days. Recently went for sram gx dub for my wife's new bike.

The Suntour XCR Jr is a pretty reasonable crank though, I'm very happy with the two that my kids are riding. Normal BCD so easy to get narrow/wide chainring and a bash on the outer (mainly as a chain guard).

4-bolt bmx cranks would do it too. I don't have a link though.

165 is short adult crank really - not sure that googling Child's crankset will help much

Googling 165mm crankset shows loads. Not sure about finding out the BCD on all of them though

You'll struggle to get a NW in 30t that isn't direct mount. I think only SRAM 94BCD will take that

My 9 year old uses a Thorn one from SJS and a 30t Superstar narrow wide.

XT M8000 comes in 165mm and you can also get an M8000 30t chainring

Similarly I've bought two in the last year or so - first was a Zee from SJS, second an XT8000 from FB Marketplace, as the Zee's are available anymore from SJS. Both were £60-ish quid. Not super cheap, but rings, BBs etc are more likely in your parts bin than square taper/old ring standards.

If time is on your side I'd suggest keeping an eye on ebay, FB etc for a suitable 165mm. Otherwise I think the mainstream new options are XT or SRAM GX. Square taper is SJS or Spa cycles.

Superstar do a 104 bcd 30t narrow wide chainring.

Good to know, thanks

I went for a SRAM GX 155, bit over enginered, but 165mm just seemed too long.

I think 30t is max too. I am sure there is a 94mm BCD on the GX on my child's bike and the chain is very close to the spider arm ends.

It’s a standard XT length and ring size. Got one on my bike. Shouldnt be any difficulty sourcing one at all.
