Sorry for the confusion. Since the bar/stem are the same piece, I answered yes - the cable exits the underside of the base bar (at its center, where the "stem" portion is). However if that's not sufficient given your frame requirements, you can exit the brake cable out the back of the "stem" portion, then back and around to your brake. Should present roughly identical frontal area, and shouldn't have any problems with cable friction or routing.

Below you can see the image you requested. It shows the distance from head tube to the centered brake cable port. It's approx 45mm forward of center, I imagine still compatible with your Lotus. But I could be wrong, and you might need the alternate path suggested above.

Just saw this....Tom(and anyone else) could the brake lever have something to do with poor braking for even a 'properly' setup Omega? I have set up several sets of Omegas on my shiv with no trouble until recently.....I have some new PD TT brake levers with less pull length than other brakes. My back Omega does not work worth a crap now....Ive reset it several times and just cannot get it to actuate properly. So, I am thinking it is possible that some guys have set their brake up properly however, have chosen a set of levers that will not allow enough actuation for the Omegas...especially on the back.

Yes. Probably not enough to warrant the vitriol some customers have expressed, so when I hear "the Omegas don't brake worth a crap," there's often some combination of setup error and/or exaggeration. But other users have opined specifically about their frustration with Profile-Design ABS levers and Omega. My favorite levers are Shimano. Either Dura-Ace BL-TT79 (carbon) or BL-TT78 (alloy). I haven't used the alloy version, but I assume the same pull ratio. Also, the Di2 TT shifter/levers (any generation) use the same pull ratio as the BL-TT79's, so they're excellent as well.

And as a followup, the Omega X should be less sensitive to lever choice, due to the new geometry, materials, and ease of setup.

Get rid of those Profile Design levers. I hated mine. I never felt comfortable braking with them. Once I went with Dura Ace levers, the braking was much stronger

Thanks for the reply Nick! I have been contemplating the Di2 TT levers...I guess I will pull the lever on them now.;)

"WHEW...I really regret that workout!"..............Noone

Thanks for the heads up. I am sure they are good levers....just not good with the old Omegas. Di2 TT levers it is....I now have a good excuse to spend the money on them.

Hi Nick,

Do you have an anticipated supply date for the Sigma X? Will you be taking pre-orders? I had always been tempted by the original Sigma, but there were a couple of things putting me off, which have been changed on the Sigma X so I'm keen to get hold of one ASAP!!

+1 on Dura Ace levers. They are the best ones I've used so far. Had SRAM 500 before with Omega front and they were useless... They were useless with the rear brake too which is an Ultegra.

Thank you for taking the time to get to the bottom of my probably unique query.

It looks like the central cable hole in the stem wont work on my frame, since centre of head tube to nose of frame measurement is about 58mm. The routing out of the top of the stem may work ok with the front brake lever on the left. I'm sure my Nokons will allow a tight enough routing. Out of interest, the cable hole in the stem, is it merely a drilled hole, or is there additional material in this area to give it extra strength against the rigours of acting as a cable stop? Would there be any reason why I couldn't drill a second hole further forward in the stem? (ignoring the fact that it wont then route through the spacers, which I'm not planning on using anyway)

Same here. TT79 levers are worlds apart from the Vision levers I originally cabled up to my Omegas. Mk1 Ventus levers work incredibly well with original Omegas too.

Will the Alpha X bar/stem work on a Cannondale Slice model, as the Cannondale Slice 2015 model has a rubber bit just behind the stem where the cables go into for the rearbrake and di2 cable, as seen in attached picture. And how would that work with the cabeling?[/img]

Yes it will work just fine. That grommet on the Slice is removable if needed.

Hi Nick,

Genuine question and I hope you understand where I'm coming from. Now that you have updated to the Sigma X stem, will you continue to support owners of the original Sigma? To use our product in a low stack setup without any spacers below, a lot of your consumers had to cut their steerer tubes low enough that it makes it impossible for us to use any other model of stem. And those who kept spacers below their Sigma might not be able to reproduce the same stack with a regular stem. We had to take a leap of faith to let us use your product!! I for one made an irreversible modification to my beautiful P3C!! If I cut my fork down low enough to use the Sigma XF that I bought, will the new Sigma mount to that? If not, are you keeping a stock of the Sigma XF (and N35) to support your prior customers, should we ever have a problem with the stems we bought?

Best regards,
Rich.

You cut your fork, you take your chances. Products change. Always leave .25 - .5cm of extra steerer.

I'll let Nick give you an actual answer now, which is most likely yes. Curious as to what supporting the purchaser of a stem looks like.

I do accept that Dave, but you can't leave extra steerer above the stem with the Sigma XF design, so if you are using it to achieve particular stack you won't be able to reproduce that with a regular stem. And if you have your stem slammed which lots of folks do, you are shut out of luck. But I knew I'd be locked in to Tririg when I did it.

I think support would look like;
"my stem broke, what can I do"
"it's ok we have more stems"
vs
"sorry we don't make those stems any more and the new one requires more steerer to clamp to" (it might not, I don't know)

I'm just a bit worried about that, but don't necessarily expect anything. But it's fair to ask, no? It's not a forty quid stem..

Cheers,
Rich.

Yes, absolutely. As of right now, we keep warranty stock on hand for everything we've ever made.

As a followup, the Sigma X clamping zone is 4mm longer than the older Sigma XF, but the Sigma X also includes the ultra-low dust cap, which is typically shorter by 10-15mm compared to standard dust caps. The result is that upgrading a Sigma XF to the new Sigma X usually means you can actually add a spacer (above or below the stem). So the upgrade path will remain for most users, but we will continue to support our existing customers.

broke down and got a(nother) "new and improved" omega. That makes #5

Has anyone fitted the new brake yet?
Was hoping to get some first impressions.

So, on my 2012 (old) P2... Will the Sigma X clean up my cabling and fit well/ make any aero difference? Looking at that and the breaks. Also, does anyone have any pictures of what the sigma x looks like when installed on a 2012 (or any year of that model) p2?

I've got it installed, working on a review of it (probably end of the week)

After a short ride though... pretty much everything good about the original, but a bit cleaned up overall. Really like the new face plate and wedge. The one downside is that the "center pull" back plate (no hanger) is an extra $50 for those who want/need it. Kinda a jump for an already fairly expensive brake, when it was an easy piece to add/remove on the original.

---

My Blog - http://leegoocrap.blogspot.com

which part was the extra $50?
The hanger is included right?

I hear you. I really wanted to make it an integrated piece like the original, but it wasn't possible given certain other design constraints. I also wanted to make it an included freebie, but that was simply price prohibitive. It's a pretty small percentage of customers that really want that part, so our best compromise was to make it an optional extra.


Yes, the cable hanger is included. The extra part is an optional back plate that *removes* the cable hanger. It is effectively the same as chopping off the cable hanger from the stock version of the brake. It really only serves as an aesthetic benefit, since our original aero testing did not detect a difference between hanger on and hanger off. Even if you run a cable hanger upstream (via a stem or headset hanger), you can still use the stock brake just as it is. Again, it's basically an aesthetic option. Granted, I do LIKE that option, which is why we still offer it. But we couldn't make it a freebie this time around.

Just to clarify:
