What are the advantages of having a road bicycle frame with lower tyre clearance? Say, I won't ever put tyres above 28mm and the frame allows upto 30mm vs a frame that has an allowance of upto 35mm.
So, what are the advantages with a frame with lower tyre clearance or the advantages with higher tyre clearance (apart from tyre size)?
Also, what difference will either of them cause while riding?
I am getting myself a custom built road bike frame - with geometry close to Merida Scultura 8000-E Disc, with slight tweaks according to my body dimensions.
It could allow for slightly better aerodynamics and a slightly lighter frame. It allows for a shorter wheel base and you don’t have to worry about toe strikes (toe overlap) too much. It also looks better.
I can’t think of any other advantages. It’s obviously possible to build frames with huge tire clearance without running into great trouble, so it stands to reason that there are very few disadvantages in ample tire clearance.
With very wide tire clearance you run into problems regarding chain line and the front derailleur (hence why most fat bikes don’t have a front derailleur or need some very awkward solutions).
