$199 for a power meter. That’s about as affordable as it gets.

The Stages Shimano 105 R7000 replaces your left crank arm. If you’re already running a Shimano Hollowtech II crankset, you’re most of the way there — you swap one arm and you’re done.

±1.5% accuracy, 200+ hours on a replaceable coin cell, ANT+ and Bluetooth, and it only adds 15 grams.

Two things to check before you order:

It measures left leg only and doubles it. Fine for most people training against themselves, but it’s not dual-sided.

Frame clearance. You need about 10mm between the crank arm and the chainstay for the sensor to clear. If you’re at 7-9mm, a bottom bracket spacer usually solves it.

It fits R7000 and other Shimano 11-speed Hollowtech II cranksets. It’ll physically install on 12-speed too, but the q-factor is 2mm narrower on that side.

Not sure if it’ll clear your frame? Ask before you order.

One of the lightest seatposts you can buy — the Gemini ÄLSAK, made in Barcelona.

Carbon with titanium hardware, zero offset, and a clamp that works with round or oval saddle rails. Starts at 92 grams. Most high-end carbon posts we carry run 160 to 200.

Two things to know before you order:

The layups. Lightweight is the 92g version, rated to 90kg rider plus bike (about 198 lbs). Performance adds 20-35 grams and takes it to 130kg (about 287 lbs). If you’re near the limit, get the Performance.

It can’t be cut. Length is a decision you make once, so measure before you order. Minimum insertion depth applies.

We stock the round version in 27.2 and 30.9, which covers most road, gravel, and mountain frames with a round post. We also carry the version shaped for the Specialized Tarmac SL8.

Which cycling metrics actually tell you whether you’re getting faster?

Josh ranks some of the most common metrics cyclists track, including power, heart rate, cadence, left-right balance, calories, training load, and speed.

Some are incredibly useful for measuring progress. Others are helpful only in the right context...and a few might be getting more attention than they deserve.

Where would you rank speed?

Someone said I got this wrong on my power meter rankings. He’s right — but so was I.

There are two different questions you can ask about your power numbers, and most people lump them together.

Accuracy: are the numbers correct?
Consistency: are they the same every day?

If your power meter reads 10 watts high every single ride, it’s wrong — but it’s wrong the same way every time. Like a bathroom scale that’s 3 lbs off. You can still track progress.

So for training against yourself on one bike, consistency is what matters. He’s right about that.

Accuracy comes back the moment your numbers have to match something outside your bike — racing indoors, moving a power meter between bikes, buying a new one, following a plan built on real watts.

Split apart: consistency is S tier, accuracy is A.

Some cyclists never think about their crankset but a erious ones do.

The SRM PM9 measures power at the spider — that means both legs, every pedal stroke. It runs 100 hours on a charge and fits almost any bike with 24mm, 30mm or DUB spindle options and your choice of crank arms.

Add the CYBREI METARBON carbon aero chainrings and you have a complete, race-ready drivetrain. We build every unit to order. SRM Cybrei

Not every power meter feature matters as much as you think. đź‘€

We ranked some of the biggest power meter features from S-tier to F-tier based on how much they actually matter when choosing your next power meter.

Battery type?
Left/right balance?
Ease of installation?
Smart features like auto-zero and active temperature compensation?

Some are genuinely important. Others sound way more useful on paper than they are in the real world.

What feature would you put in S-tier?

Everybody wants this bike. Nobody can get it. Here’s the way around that.

The XDS X-LAB GT8 has been one of the most in-demand gravel bikes out there — Velo called it “absolute dead-center of the current gravel consensus,” and half the YouTube coverage is some version of “how is this so cheap.” It’s also been sold out for a long time.

The frameset arrives September 1st. $1,999.

Toray T-800 carbon frame and fork, 3.92 lbs for a size M. 55mm tire clearance, internal downtube storage, UDH hanger, T47 threaded bottom bracket, mounts everywhere for bikepacking. Lifetime warranty on the frame with registration. XS through XL.

If you can find the complete bike, that’s a hell of a package. But nobody has it, and nobody knows when it’s back. This is how you get the frame.

It’s up on the site now — you can sign up to be notified when it lands.
