Question Re: TriRig Speed Concept Clamps

I guess there are a certain number of folks out there now that were able to get in on the order for these clamps and have been using them for some time now. I just purchased a set here on ST and installed them, they certainly clean up the front end of the Sped Concept and put my pads exactly where I need them. Does anyone out there have any feedback on these? How are they holding up? Any issues with the bolts loosening over time etc? Can you feel the bolt heads through the pads on long rides? Any other feedback?? Thanks in advance!

Where’d you get the clamps? I’m interested in getting some.

they did a one time only order for them a few months ago

I missed out on teh official order but managed to buy a set off someone on ST who had purchased them but didn’t sue them. I’ve been riding with them now for about a month and I must say they are great!!!

I got them. Love them. Can’t feel the bolts. My only complaint is that they are a bit tight and I actually had to pry them open to get my bars into them. They also take away most of the adjustibility of the system so if your don’t rest right on top of the spacers these things may not work for you.

I think that there is enough demand out there that Nick might be able to be persuaded to do another run. I think he’d be better off selling the concept to Trek and making a few bucks.

It looks from the pictures like, in order to move the cups narrower, one might need to use a spacer in order to elevate the inside edge of the cup over the extension. Is this right? I ask because the added height of the required spacer would negate some (but obviously not all) of the benefit.

That’s correct - you’d need a 10mm spacer above the clamps to move your cups closer together. The clamps lower the minimum stack height by 25mm, so you’d still be getting 15mm lower even with that change. But if you needed -25mm, and narrower arms, the these cups aren’t for you. And in fact, there is no available solution for doing that, short of buying a smaller frame. Anyway, stack height is just one of the benefits (-200g weight, -10 bolts, eliminates tilt slip, more aerodynamic, more elegant, etc). I ride exactly that way, with one spacer above the clamps. But my cups are set wide. That’s just what I happened to need to achieve my position.

Another benefit here is that even if you don’t need to ride the clamps slammed, you can use them to change the relationship between your pads and your extensions - that is, the clamps can be put either right underneath your pads, or anywhere in your spacer stack. So you can fine-tune the optimal elevation of the shifters given your extensions. Personally, I think the stock SC extension put the shifters too high. So if you were using 30mm of spacers, you could put the clamps at the bottom, and 20mm of spacers above it, to effectively lower the shifter height by 20mm.

Just as a PSA, there will be one final batch of clamps available next month in the TriRig store. Then I’ll probably drop them entirely to focus on the Omega brake.

Yes, if I am understanding your question correctly you need to elevate the cups with a spacer to get them to the closest position width-wise. I believe you can run no spacer on the bottom and get that lovely near zero stack height but at the cost of having to have your pads partially outboard of the extensions instead of centered over them.

Right, Nick is a bit more qualified to comment than I am :wink: . BTW Nick, these are just such an elegant solution. Love mine.

Thanks. No doubt there are many worthwhile benefits apart from stack height, and I intend to snag some when they come available; I was just curious. As others have said, it’s an ingenious and elegant piece of engineering. More broadly, I’ve been referring people to your site frequently – thanks for your contribution to the triathlon community.

Thinking more about this – probably unwisely – is there a good reason not to shave off the inside of the cups so that they could be lowered the full 25 cm and also narrowed? I run with a bottle clamped between my forearms as it is, so the inside lip of the cup doesn’t seem necessary from an ergonomic perspective, but I imagine it could play a role in terms of structural integrity and ability to support weight.

Honestly, I think you’d be fine doing that, but proceed with caution.

Just ordered a set of these…can’t wait to get them on and dialed in. Thanks!

What bolts are people using? It seems that the stock bolts are too long. If you are buying them are you using aluminum or steel and what about the washers?

You should have several different length bolts with your spare parts that came with the bike. The different length bolts are meant to accommodate variable spacer stack options. There are probably some washers in that spare parts bag as well.

I LOVE mine. I’ve had them since the initial run and have many, many rides and races on them. The weight they shave is crazy. I switched to HED aero extensions which are also much lighter. Use the long bolts that go through the basebar. Pick the size that works best for your stack. I got some CeeGees replacement pads and I don’t feel the bolt heads at all. Nick did an awesome job with these. I hope that, since I was an early-adopter on these clamps, that I’ll also get that opportunity when his new brakes are available. I now own what is alleged to be the very first Cervelo P3 ever shipped to a US customer. I’ve rebuilt the frameset with modern components and the best fork I could find for it. Nicks brakes will be the perfect finishing touch. Of course, I’m fond of stopping when I really need to, so I’m anxious to be an early adopter, but not a guinae pig! :wink:

I am already using the shortest bolts (I think) and they’re too long with no spacers.

Yeah, if you run zero spacers and just the clamps, even the shortest stock screws will be too long. But they’re standard M6 screws, and available at any hardware store. Just bring your existing screws when you go shopping so you can compare length, head size, and thread pitch.

Or you could bust out a dremel and shorten your existing screws a bit.

I cut my longest stock bolts to do exactly that (figuring I might want the short stock bolts some time in the future). Thread a nut onto the bolt above the point where you’ll make the cut. Use a hacksaw or a dremel to remove what you need to. Err on the side on not removing much, I think I took off 1 cm or so, marking my cuts based on about 5 mm off the short ones. File your cut to get the ends and threads more or less even and low. Use the nut you threaded on above the cut to clean the threads up further by going over it them a few times.

FWIW it might be challenging to find bolts that work at your local hardware store. Most thread pitches available are not going to work. I think Dan or someone suggested an online hardware company that has pretty much everything. I can’t remember what the thread pitch on them is but it was talked about in the SCOT.

Unrelated question to initial post, but…
Any Tririg SC Clamp users have issues with the stock armrest cups flexing down too much under weight
of arm/elbow. The stock Bonty armrests are a less dense plastic and it seems that my elbows want to slide laterally. Also, the
inherent design of the clamps pitches them slightly down to pinch the aerobar tight. Granted,
my arms may prefer a wider armrest position. But I love the minimal design and my BTA applications are smoother.
I’ve experienced with adding a bracket under the armrest to help support the flexing armrest. Works better.
Anyone have the same issue?
