The Dupli-fit seems like a great tool for easy setup. Also seems ripe for an App to handle coordinate conversions. I found a basic app on the App Store but a more specific version wouldn’t be too hard. An iPhone mount (or two) would also allow for more precise measurements of the angles. Rubber bands would probably work for that too or a 3D printed adapter.

It would be great if you could use the buttons on the SRAM Red shifters to shift the Classified hub. You can use them to control a Garmin (a competitor product to SRAM's Hammerhead), so I don't see why SRAM wouldn't let Classified use it to shift the hub. Is there a technical reason it couldn't work or just a protocol/licensing/legal reason?

I’m not sure about technical reasons, but from a brand perspective, it’s completely understandable why SRAM would have zero interest in allowing people to pair its controls with components from another company.

One of the early hopes from folks when Classified first launched was that SRAM would just buy them since it made so much sense for it to all be bundled together. But alas, Classified apparently has bigger plans.

Does the RainX do anything for fog? That’s my main nemesis

Haven’t tried it in that situation, but I’m guessing it won’t be very effective, at least not initially. Those droplets will probably be way too small and won’t roll off until they start to form bigger drops.

I’ll admit that after a very hilly gran fondo last year I’m interested in the Hope 4-piston brakes.

I’ve rarely encountered anyone who complained their brakes worked too well.

Wolftooth's numbers might benefit from some rolling resistance data to back it up. On the one hand, the pressures are nearly identical to what I've arrived at on my own. On the other hand, I also used to think 100psi felt the fastest rolling.

GCN has done a variety of rolling tests on their YouTube channel using the SRAM app to set pressures. Unless you’re on a track 100psi is way too high on modern tires.

I am looking forward to the review of the Formula calipers. I am happy with all my MTB brakes but disappointed in the handful of SRAM road calipers I have. The Paul Component Mini-Moto/Touring Canti setup on my CX bike out performs all my SRAM road set ups. I may give the calipers a try once a long term review comes out.

What haven’t you been happy about with those? And which SRAM brakes and levers?

Rival. They seem either seen on or off on both my Crux and Aethos. I’ve done the bed in processes and road on each for a year. A bleed helped some. They are ok but nothing special.

Hi James. What gives the formula caliper more power? Larger pistons? Pad compound? I would also be really interested in what the pad retraction is like and is there rubbing, etc.. This is because to get greater pad force due to bigger pistons the pad travel has to be reduced. Since the volume of fluid moved by the lever is the same as that added to the caliper and, if the pistons are bigger, then the travel has to be smaller to have the same fluid volume.

My apologies for the delay, but I only just recently heard back from Formula. Still trying to get a bit more information, but it *sounds* like the pad clearance is comparable to stock.

"Indeed, we increase the hydraulic ratio by using a larger caliper pistons but this is only possible due to the higher stiffness of the caliper. Stiffer caliper ---> bigger piston allowed without sacrificing the feeling = more stopping power and higher thermal stability.

"It’s also worth noting the quality of rollback seals, piston material and the crazy expensive lube used in assembly help with feel.”

Confirmed: no claimed reduction in pad clearance.

Great question! I don’t have an answer for you, but I’m sure I can find out.

As you said, though, that additional power doesn’t come for free.

James, a request for your to-do list: an update for the Coros Dura now that they have had a chance to roll out software updates

Already been on my list! Short answer: it’s definitely better, but still not on par with top competitors, particularly with navigation. If you need/want a more basic setup, however, I’ve actually come to like it a lot. The battery life is INSANE.

As a randonneur and route creator the navigation part is my main interest. I am generally happy with my Roam v1, but there are some issues with how Wahoo handles cues when a route is loaded, often changing custom cues from RwGPS

Navigation is absolutely not the Dura’s strong suit.
