Hello

Firstly Thanks for all the help you all gave me when deciding on my Carbonda frame and components - ended up being a really nice bike.
Now my girlfriend have tried my bike a few times and would like to build her own, but she likes hardtails more than fully.
So we have looked at the SPCycle SP-M016 frame, where the sellers recommend a 17" for her(she is 169cm tall) but looking at the numbers of her current bike(Giant Liv Tempt E+ 2 medium)and my carbonda FM-1002 large, we are leaning most towards the large with a short stem as the stem on her current bike is like 70mm.
Looking forward for your feedback and replies.

My daughter is about the same height and her 17 inch M016 with a 45mm stem is a great fit. Fit can be personal preference but I think the 17 inch would be the right choice.

Thanks for the response. Always good with a second opinion.

I can get a good price on a complete Shimano M8100 groupset, but the M8100 has a 52mm chainline, and with 32T it might not fit the frame.

I'd opt for the 8120 crankset with the 55mm chainline if you can. I don't see the 52mm version fitting with a 32t ring.

I found a deal on a SLX 7130 crankset with the 56.5 mm chainline that I'm going to try once I swap some parts around between bikes. I'll post up the results once it's installed, it will be another month or so though.

I put a long armed, long legged, short torsoed 5'9" on the 17" (medium). Note that the seat angle is not super steep, so the Effective top tube is a bit longer.

I am running the max shortest stem widely available for this rider as well, 30mm.
