Still seeking to identify an option or waiting on a TriRig sale.

First question... Are you sure that it is a TRP 922.1 brake? Felt's site simply lists it as a "Felt Aero TT / Tri."

I am not familiar with the 922.1 brake or its mounting system. But, the TRP website offers little encouragement. It says "This brake is not Shimano Direct mount compatible and will only work with bikes designed for this brake." So, I assume that your options are pretty limited. In fact, you would probably need to confirm whether the Omega X brake's adapter is compatible.

If you could figure out an adapter, I would recommend the Ultegra direct mount as an less expensive alternative to an Omega X or another TRP. I like the Ultagra DM, because it has a top pull rather than a side pull cable entry. This simplifies the cable run and gives you a cleaner, lower friction brake route.

I can confirm that it is a TRP 922.1 brake used on the B14 setup. I had to lookup the user manual to figure out how to adjust to fit my new carbon rims. I do agree it is a horrible setup and doesn't make for easy adjustments. I'd also like to hear about any prossible replacements for it but i have a feeling that felt designed the frame mounts to specifically work with this brake alone.

A couple updates on this from another thread... Tririg Omega X brakes are compatible with that TRP standard, and the Dura Ace 7800 direct mount brake will also work.

The new Omega X looks like it is fully compatible according to their compatability chart here -> http://www.tririg.com/...p;page=compatibility

The brake is only $60 more than a replacement TRP brake and they have a sale on now for 10% off. I'm seriously thinking about getting one as adjusting that rear on the felt is horrendous.

I have a brand new Omega SV that I bought as a replacement for my TRP undermount but never used before selling the bike. I hated the TRP. It looked like the Omega would have been a huge improvement if I had kept the bike.

Just do it! The brake is wonderful. I have a pair of them on my IA 16, and they are worth every penny.

Thanks for the heads up on the TriRig sale. I've been holding out since I'm only doing trainer work outs right now. I placed my order and am hopeful this works a lot better. I will wait to see how this mounts but maybe I won't have to remove the brass sleeve stuck to the brake mounting post.

Im not sure what sleeve youre referring to but fron what i can tell from their installation instructions you will nees to mount the Low DM adapter to your existing brake mounts and then the omega mounts directly onto the adapter with a single screw.

If you look back to the first post you'll see that my TRP brake came apart when I removed it from the bike. The inner brass bushing, or sleeve, is corroded to one of the brake mounting post. It's not going to come off easily and not likely in one piece. If the Omega bracket fits over this bushing then I won't have to remove it. It's not thick at all so I have my fingers crossed.

I just installed a Tektro T741R https://www.tektro.com/products.php?p=55 on a new Felt FR1 build. It is simple, elegant, powerful, and easy to adjust. The barrel adjustor is where it should be, doing away with inline adjustors, QR's,
and the like. They only seem to be available directly from Tektro as they are pretty much an OEM only product.

I received my Omega X. I haven't started the install yet but I did watch TriRig's video. In the video it appears he removed the brake mount posts and then installed the mounting adapter. Am I correct that these need to be removed? Did you remove the rear brake posts on your IA? If so, did you use any lubricant, heat, etc.?

If anyone else has removed these posts, any tips or suggestions would be appreciated.

Roger

Yes, the canti studs must be removed in order to install the Omega X and it's Direct-Mount Adapter. It takes a good deal of force to remove the studs, as they are typically installed with thread locker compound. I've done it myself on many bikes, it just takes a lot of torque. Many people think or assume that too much torque in removing them will damage something, but it never does. Just get a good wrench and turn. They are standard threaded, so counter-clockwise to remove.

TriRig, thanks for the reply and advice. The fit and finish of the brake, as well as the smooth and simplistic movement, make this look like a really nice upgrade.

Roger

I understand the Omega-x does not fit the Felt DA because it uses linear pull brakes. And these have the studs in a different position in respect to direct mount brakes.

However, I should be able to build an adapter provided I have the specs, that is, the distance between linear pull brakes studs and direct mount bolt locations. Do you know this dimension or where I can find it?

I'm sorry but I can't endorse or assist with that use case, as we haven't tested it ourselves and can't ensure it's safety. I know you're just asking for dimensions, but I don't want to tacitly endorse the use you're suggesting without knowing it's safe first.

I was able to successfully remove the posts on my Felt B14 without issue. A 5/16" wrench fit mine and I slipped a short pipe over the end of it for some additional leverage. I really appreciate the stainless steel hardware given the environment this brake operates in. I need to swing by the bike shop tomorrow to pick a cable housing ferrule and a cable end cap to complete my installation.

One question, from my car maintenance and repair work I have developed the habit of using blue thread lock on nearly all threads. Any reason you would advise against it?
