:( The Omega does not fit on the rear of a Scott Plasma 2 due to the height of the arch and the brake gets bolted to a plate then mounted to the frame. The arch blocks the bolt you need to tighter to put the plate on the frame. I have an email into Nick but I don't really see a work around on this one.

PS Pretty powerful on the front!

Juanmoretime - if you got a thin hex head bolt, could you not use this to attach the plate to the frame by using an open ended spanner rather than allen key? I have the same issue fitting the Shimano AX brake to the rear of my Cervelo P3. If I understand correctly, the Plasma fitting sounds very similar to the Cervelo.

I wish.

When the Omega is mounted not only does it cover the bolt. The plate is plastic covered and the allen key is deeply recessed and there is only a couple of millimeters between the plate and the brake. It looks like a total no go.

Anyone interested in a new Omega?

Okay, looks to be a different design to Cervelo. Pity it may not fit!

Would love to buy the brake off you, but have been buying too much of late and need to stop... :oops:

I think the EGG on the back with OMEGA on the front would be a good combo. Double OMEGA would be better. :D

@Juanmoretime I had to remove the cover and cable hanger piece in order to install it on my p3, your photo has been deleted so i can't see whether this would work for you or not? I then re-assembled the brake in situ.

Edit:- just found a photo online of the plasma 2 rear brake area, would it not work if you spaced the omega out further by using multiple serrated washers, not the most elegant solution I realise!

They do brake fabulously too, although they were only used 3 times on last nights TT!

I'm think if I reverse the mounting bolt and attach it to the plate and use a nut as a spacer and to lock it in place. Then mount the plate I'll have a threaded "rod" to mount the brake. I can then mount the brake using a cut down brake nut and a thin washer securing it from the inside of the brake. :idea:

Heres a couple of photos of my rear brake, trying to improve the aerodynamics with a little bit of gaffer tape and card. :)

Now with added fairing:-

I think this should help smooth airflow round the edge of the brake which was sticking out a little. and its relatively stealth modification in real life.

Chances are he is a triathlete and the regs are most likely not that strict where he races.

That is clearly structural and provided by the manufacturer.

UK TT scene, their own regulations not UCI ones! Only 1 UCI race per year, the sporting National Champs (as opposed to the fixed distance champs run by the UK TT body). 2 seconds to remove a bit of tape and card before hand.

Wow, very cool. I may have to try that on my fork!

Does anyone know where you can get "gaffer tape" in the US? It looks like black duct tape.
