I’ve been looking at the Salsa Warbird. They recommend their 49cm size for riders between 142cm and 157cm.
Probably not. What they call 50 has a 52.5 TT and 75 degree seat tube angle. That's what I use at 5' 8".Niner has a 47cm and a 50cm in their RLT 9 and RLT 9 RDO bikes, one of those would surely fit.
Thats what I figured. She's on a custom with 26" wheels, fits good but it is getting hard to find wheels and tires.Probably not. What they call 50 has a 52.5 TT and 75 degree seat tube angle. That's what I use at 5' 8".
What they call a 47 has a 51 TT. Still seems a big big for a 5 foot rider but maybe with a really short stem.
I believe just about any bike with disc brakes that comes stock with 700c rims can also use 650b rims.Old thread I know. But the Litespeed Watia in XS fits my wife who is about 5'. Reach is fine and the standover is OK on the 700c wheels, but I put 650B wheels with 35mm tires on them to give her another couple of cm of standover. With 165mm crank arms, pedal clearance isn't an issue at all for her.
FWIW, I have a Lynskey GR300 and they also make an XS size and the geometry is almost exactly the same.
Both of those frames specify that 700C or 650B wheels can be used.
Check out the geometry and measurements of those frames and you can then compare to any other brand and, if it's similar, I believe it would fit fine. Especially if there's a 650B option.
