Has this been done? ( disc brake content )
Hi all,
This may be a stupid question and maybe an obvious answer that I’m not seeing, but I will ask it anyway...and flame away!!! On a rim brake bike, what would be the ramifications of replacing the fork, brake caliper and left shifter to a hydro disc brake set up and leaving the rear brake as a rim brake? As always, thank you all in advance! Steve |
Sure lots of bikes are set up this way. As long as the fork is specced the same in length and similar rake there is no changes other than the braking which i assume you will prefer since looking to change it to disc.
Obviously you will need at least 1 new extra front wheel as well but other than that.. |

Steve, I did this to a mid-90s Trek 750 (aka 520) CrMo frame, replacing the stock tubular steel fork with a Nashbar carbon disk / canti fork, set up with a mechanical disk brake.
The bike isn't used much but it has worked well so far. |
Anyone know of an 1 1/8th straight fork, 43 rake that is 100 x 12 thru axle?Seems the world has moved on from 1 1/8 disc forks and are now all 1 1/4 or tapered.
Thoughts??? Thank you! S |
They are mostly 1 1/8th tapered to 1 1/4 or 1 1/2 now. Straight with thru axle is a rare bird, but somebody must have made them. For a Mullet application, A straight steering tube qr fork would be fine. ;)

You don't need a complex analysis to know this, you just need to look at the locations that the forces get transferred into and out of the fork/wheel. Forces are transmitted to the wheel/fork from ground at the bottom of the wheel; forces are transmitted from the wheel/fork to the frame at the headset bearings. For the same force applied by the ground to the bottom of the wheel, the same forces will be transmitted to the frame at the headset bearings. What's going on between them won't change the forces transmitted from ground to frame. |

I think you're looking at a new wheel for this project. |
