Key SRAM Force AXS E1 Crankset Features

One-piece aluminium chainrings improve stiffness, durability and front-shift accuracy.
X-Range gearing uses a consistent 13-tooth jump to reduce disruptive cadence changes during front shifts.
Carbon crankarms combine low weight with efficient power transfer for climbing, sprinting and fast bunch riding.
Available with 46/33T, 48/35T or 50/37T gearing to suit different terrain and rider strengths.
Eight-bolt direct-mount architecture provides a straightforward path to compatible SRAM AXS power measurement.

The most versatile all-round option for club racing, fast bunch rides, rolling terrain and long-distance road cycling.

50/37T

A higher-geared combination intended for stronger riders, criterium racing, flatter routes and consistently fast road riding.

Carbon crankarm construction

The SRAM Force AXS E1 Crankset uses reshaped carbon crankarms to balance stiffness, low weight and durability. Carbon allows material to be concentrated around high-load areas while reducing unnecessary mass elsewhere.

This construction produces a direct response during out-of-saddle climbing, hard acceleration and sprinting. It also helps reduce the overall groupset weight without moving to the considerably more expensive SRAM RED crankset.

One-piece aluminium chainrings

The inner and outer chainrings are manufactured as a single integrated structure rather than two separately attached rings. This architecture was previously a key differentiator of SRAM’s flagship road cranksets.

The one-piece construction provides several benefits:

Increased lateral stiffness
Precise spacing between chainrings
Consistent interaction with the front derailleur
Faster shifts onto the large chainring
Reduced movement between the two rings
Lower structural weight
Improved long-term shift consistency
Clean, premium appearance

The principal trade-off is replacement cost. The inner and outer rings cannot normally be replaced separately, so the complete chainring assembly must be replaced when the teeth are worn or damaged.

X-Range gearing

SRAM X-Range gearing uses relatively compact front chainrings with road cassettes that begin at a 10-tooth sprocket. This provides substantial high-speed gearing while reducing the difference between the front chainrings.

All three combinations use a 13-tooth jump:

46/33T
48/35T
50/37T

The smaller chainring difference limits the change in cadence when shifting at the front. It also reduces the number of compensating rear shifts required to return to the rider’s preferred cadence.

Eight-bolt direct-mount interface

The chainring assembly attaches through SRAM’s eight-bolt direct-mount system. This creates a stiff connection between the crankarms and chainrings while providing compatibility with approved SRAM power-meter components.

160mm crankarms

The shortest option can suit smaller riders, cyclists with restricted hip mobility and triathletes seeking a more open hip angle. It also increases pedal clearance through corners.

165mm crankarms

The 165mm option has become popular among riders moving away from traditional longer road cranks. It can reduce peak hip and knee flexion while supporting a smooth, high-cadence pedalling style.

170mm crankarms

The 170mm version provides a versatile middle ground and suits a broad range of road cyclists. It delivers a familiar feel while offering slightly more pedal clearance than longer options.

172.5mm crankarms

The 172.5mm version remains a common road-racing standard. It suits riders whose existing fit, flexibility and cadence work well with a moderately long crank.

Crank-length fitting considerations

Moving to a shorter crank changes the position of the pedal at both the top and bottom of the stroke. Saddle height normally requires adjustment to maintain similar leg extension.

For example, moving from a 172.5mm crank to a 165mm crank may require an initial saddle-height increase of approximately 7.5mm.

Its stiff one-piece chainrings provide crisp front shifting across rolling roads, while the three gearing combinations let riders tailor the bike for flat criteriums, mixed-terrain bunch rides or steep alpine routes.

Cyclingnews published its Force AXS review on 27 June 2025 and concluded that the system provided excellent performance while narrowing the gap between Force and SRAM’s flagship components. The crankset’s carbon construction and integrated chainrings formed an important part of that improved weight and performance package.

Slowtwitch assessed SRAM Force AXS from a triathlon perspective on 13 May 2026. The publication concluded that most triathletes would find it difficult to justify SRAM RED’s substantially higher price because Force delivered very similar practical performance, with much of RED’s advantage confined to lower weight and more premium finishing.

Routine cleaning

Wash the crankset with mild bicycle cleaner, clean water and a soft cloth.
Avoid aggressive solvents and abrasive polishing products.
Do not direct high-pressure water at the bottom-bracket seals.
Remove accumulated chain lubricant from the chainrings and crankarms.
Dry the crankset after wet rides.
Keep strong degreaser away from the bottom-bracket bearings.

Carbon crankarm inspection

Inspect the crankarms regularly for:

Cracks
Deep scratches
Gouges
Raised carbon fibres
Crushing damage
Pedal-thread damage
Damage around the spindle
Heavy heel rub
Significant impact marks

Stop riding if structural damage is suspected. Carbon crankarms should not be repaired with cosmetic filler, glue or general-purpose resin.

Chain and chainring maintenance

Clean and lubricate the chain regularly.
Select lubricant appropriate for local weather conditions.
Remove excess lubricant to reduce dust accumulation.
Measure chain wear with a compatible chain-checking tool.
Replace a worn chain before it damages the cassette and chainrings.
Inspect the chainrings after a dropped chain.
Check the teeth for hooking, deformation or impact damage.
Use compatible SRAM chains and drivetrain parts.

Bottom-bracket maintenance

Check for bearing play, roughness and creaking.
Confirm that crank preload remains correctly adjusted.
Inspect the spindle and seals during scheduled servicing.
Replace contaminated or worn bearings promptly.
Have persistent noise diagnosed by an experienced bicycle mechanic.
Avoid assuming that every creak originates from the bottom bracket, as pedals, chainring interfaces and frame hardware can create similar sounds.
