With or without power.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eSRAM's most refined aluminum road crankset. The arms are shaped to put material only where load actually goes, the 48\/35T rings are integrated as a direct-mount unit rather than bolted on, and the whole assembly runs a DUB spindle for a simpler, more durable bottom bracket interface.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in 165mm and 170mm arm lengths, standard or with an integrated spindle-based power meter.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eStandard or power?\u003c\/h4\u003e\n\n\u003cp\u003eMechanically these are the same crankset. Same arms, same 48\/35T X-Range rings, same DUB spindle, same chainline, same shifting. The power version adds a strain gauge inside the spindle and weighs under 40g more.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGo standard if\u003c\/strong\u003e you already run a pedal-based power meter, you train by feel or heart rate, or you're building to a budget and power isn't the priority.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGo power if\u003c\/strong\u003e you're training with structure, riding indoors on a smart setup you want to cross-reference, or planning to add power eventually. Buying it now is a modest step up from the standard crank. Adding it later means buying a second crankset — or a pedal system that costs considerably more than the upgrade.\u003c\/p\u003e\n\n\u003cp\u003eThat gap is the whole argument. A standalone power meter typically costs more than the difference between these two, and this one adds no extra component to charge, install, or move between bikes.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eHow the power meter works\u003c\/h4\u003e\n\n\u003cp\u003eThe strain gauge lives in the spindle rather than in the chainrings, pedals, or crank arm. That location keeps it protected from crash damage and rock strikes, and it means the measurement doesn't change when you swap chainrings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIt measures your left leg and doubles it.\u003c\/strong\u003e This is a single-sided system — it reads left-side force and calculates total output from it. Worth understanding before you buy:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor training, it works.\u003c\/strong\u003e Structured training depends on consistency, not laboratory accuracy. The same meter reading the same leg the same way, ride after ride, gives you intervals, zones, and progression you can actually train against.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt won't show leg imbalance,\u003c\/strong\u003e because it can only see one leg. If you're rehabbing an injury or specifically chasing L\/R balance data, you want a dual-sided system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIf you have a significant imbalance,\u003c\/strong\u003e your total number will skew in whichever direction your left leg differs. It'll still be consistent — just offset. Most riders' imbalance is small enough not to matter for training purposes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eBattery and durability\u003c\/h4\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e400+ hours per battery.\u003c\/strong\u003e That's a full season for most riders — ten hours a week gets you through most of a year.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUser-replaceable AAA lithium battery.\u003c\/strong\u003e No charging cable, no dock, no proprietary cell. Use a lithium AAA, not alkaline — alkaline cells drop voltage differently and give you unreliable readings and short life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIPX7 rated\u003c\/strong\u003e — submersible to one meter for 30 minutes.

They aren't — they're part of a different system.\u003c\/p\u003e\n\n\u003cp\u003eTraditional road gearing pairs a 50\/34 chainset with an 11-tooth small cog. X-Range pairs smaller rings with a \u003cstrong\u003e10-tooth\u003c\/strong\u003e small cog on the cassette. A 48T ring over a 10T cog gives you a higher top gear than 50 over 11. You give up nothing at the top end.\u003c\/p\u003e\n\n\u003cp\u003eWhat you gain is the jump between rings. A 50\/34 asks you to swallow a 16-tooth change every time you shift the front. This is a \u003cstrong\u003e13-tooth jump\u003c\/strong\u003e, which means less cadence disruption, fewer compensating rear shifts, and a smoother progression through the range.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e this only works with an X-Range cassette that has a 10T small cog. Running these rings against a conventional 11-speed or 11-tooth cassette gives up real top-end speed.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eCrank length — 165 or 170\u003c\/h4\u003e\n\n\u003cp\u003eShorter cranks have quietly taken over road and gravel fitting, and for good reason. A shorter arm opens your hip angle at the top of the pedal stroke, which makes a low, aero position sustainable for longer and takes strain off the front of the hip. It also raises pedal clearance, which matters on gravel and in crits.\u003c\/p\u003e\n\n\u003cp\u003ePower loss from going shorter is negligible for almost everyone — riders self-select cadence to compensate within a few rides.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e165mm\u003c\/strong\u003e — riders under roughly 5'8\", anyone chasing a lower front end, anyone with hip impingement or tight hip flexors, criterium and gravel riders wanting clearance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e170mm\u003c\/strong\u003e — the general-purpose length for most riders 5'8\" and up, and the safe pick if you're currently on 172.5 and unsure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGoing shorter raises your effective saddle height. If you drop from 172.5 to 170, raise your saddle 2.5mm. From 175 to 165, raise it 10mm. Get that wrong and the new cranks will feel worse than the old ones for reasons that have nothing to do with the cranks.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eDUB\u003c\/h4\u003e\n\n\u003cp\u003eDUB is SRAM's spindle and bearing standard. One spindle diameter works across every frame's bottom bracket shell — you change the bottom bracket to match your frame, not the crank. Larger bearings than the standards it replaced, which means longer bearing life and a stiffer interface.\u003c\/p\u003e\n\n\u003cp\u003ePractically: this crank fits any frame, as long as you buy the correct DUB bottom bracket for your shell.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch4\u003eYou will need a SRAM Flattop chain\u003c\/h4\u003e\n\n\u003cp\u003eThis is the mistake that costs people a weekend, so it's worth being blunt about.\u003c\/p\u003e\n\n\u003cp\u003eSRAM's 12-speed road drivetrains use \u003cstrong\u003eFlattop\u003c\/strong\u003e chains, which are a different design from standard 12-speed chains.
