Tapered 1.25 headset question

The industry has forgotten about 1 1/8" disc forks for good reason - so that you have to buy a new bike 

Enve make 1 1/8" carbon forks. What's wrong with your current fork though, there's a lot more important factors in fork design than the size of the bearing race, like rake and trail. My best handling bike has a 1" steel fork with external headset.

Have you checked fatbirds.co.uk, more carbon forks than Ive seen elsewhere.

Ok, I'll put in my pennyworth and await being corrected by those with more techie knowledge.

I think you would need a 44mm zero stack headtube to have a choice in this, but I await correction.

My question to you is that, particularly on a road bike, is this really an upgrade?  I don't think I have ever thought that the weakest spot on my bike was the dimensions of the steerer tube.

My understanding is that the main reason for the increase in the popularity of tapered steerers/headtubes is that it makes it much easier to get the bladder out when carbon fibre frames are being manufactured.  The marketing types then turn a manufacturing convenience into a selling point, but that's what they are paid to do.

I fully accept that intuitively "wider at the base" seems to make sense, but I'll bet if plain gauge were the easiest manufacturing option, we would all be getting sold how consistency in the diameter of the steerer tube was the latest innovation in improving bike handling. 

Looking up FSA 53-1 do a headset for 1"1/8 to 1"1/4 forks. You would need to measure the internal diameter top and bottom of your bike frame. It takes a little research sometimes and maybe an email enquiry.
