Hello,
I have checked and contacted some seller such as Velobuild but I haven't been able to find if there is any model of gravel frame with UDH hanger.
My idea is to build a bike with a mullet (GX T-Type + Force 1x crankset).
Given that there are several differences when it comes to tyre clearance, I guess that to work with UDH - T-Type, that have not much to adapt in the micro-adjust (just +-2 I think)... Will it be a nightmare to set the bike up properly to have the correct chainline?
Maybe is better to stick to regular hangers and use non-t-type mullet setups?
Thank you in advance for your help and sorry for my English
