Would you change the saddle?

It’s important to set your saddle height relative only to the reach of your leg. I believe the correct height is when your leg is straight, seated on the saddle with your heel on the pedal. Therefore a slightly bent knee when your toes are on the pedal. That’s the correct position regardless of climbing or not. So I’d advise to find the correct saddle position first. I don’t know if you’re tall or not but I know people who like to set their saddle too high for climbing, I’m wondering if this might be the case for you? Correct saddle position; it’s about looking after your knees and muscles etc first and then efficiency comes into it as more of a secondary factor.

If the pictured saddle height is correct, and you’re uncomfortable, then I think that frame is a touch too small for you unfortunately. At that point it’s up to you if you want to find all the tweaks to set it up in a way that works for you.

Edit; I think your bike looks cool though! And it doesn’t look like it’s too small for the rider the way it’s setup, maybe getting close though. It also appears that the nose of the saddle is pointing slightly down. Try levelling it off a bit

I think it looks great. If it fits your bum, then leave it.

It looks rad, butt if it taint feeling right you should ass-k your grundle what needs changing.

I’m gonna say something wild. Black seatpost

Looks good to me, I have a bike with a super similar setup.

Lower the saddle a cm or two and tilt the nose up to level or just slightly pointing up. Leg extension should be more or less the same and it’ll look less goofy

I like that saddle matching the grips

Beautiful
