Disc Fork on a road frameset (replacing Road Fork with Disc Fork)

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Disc Fork on a road frameset (replacing Road Fork with Disc Fork)

Hello-
The winter grit has me going through Front wheel braking surfaces at an unsustainable rate.
I'm thinking about replacing the front fork on my Ridley Damocles (1 1/8" to 1 1/2" tapered steerer tube) with a compatible disc fork, and then run a disc front wheel and use the existing rim brakes on the back.
Also-I understand that in this conversion axle to crown distance is an important factor. So long as I get a fork with the same axle to fork crown distance, I should be ok. I think...
This bike is what we in the Northwest refer to as a "Rain Bike", or a "commuter". Not a race bike

Buying a new disc frameset or full bike is not an option financially at this point.


Here's my question:
What are the potential drawbacks for doing this? Is there any reason this would be a bad idea?


Thanks !

Is your current fork 1 1/2" to 1 1/8" tapered?

Are you using mechanical/cable, or hydraulics, or cable actuated hydraulic brakes?

Oh, I had troubles with my vintage "Blaze style" brake levers not pulling quite enough cable for the rear disc on one bike I built up. Perhaps also using too much housing. Anyway, make sure your brake caliper is rated for "road/cross".

Otherwise, the conversion should be fine. Forces on the frame for discs/rim brakes should be similar.

How quickly do you chew through rims? Aluminum? If you can build your own wheels, it may take some time before your upgrade pays for itself.

I’ve been pretty anti disc on a road bike but now that I think of it a disc on the front only sounds like a great idea.

I have SRAM Rival mechanical brakes. Will keep those.
I usually buy Aksium front wheels at about $90 a pop.
I think 2 winters should give me a good ROI.
Hey-Thanks!

Sounds OK. Fork rake/trail should match. If not handling will be different.
I think there is no difference in head tube - but that is me guessing.

Are you going to have a hydro brifter and cable one?

^^ I agree about fork rake and trail.

Try to get a fork with the same offset so that handling is not negatively affected. Fork manufacturers don't always provide this information.
