The 1x compatibility makes it a straightforward upgrade for riders seeking a cleaner front end and less chain management. While the specific BB width isn’t stated here, Shimano GRX components typically align with common road/gravel standards, making installation straightforward for compatible frames.
SRAM APEX 1X Wide Dub Crankset 165mm DM 40T Aluminum NO BB
SRAM APEX 1X Wide Dub crankset offers a streamlined, single‑ring design with a wider chainline for gravel and mixed-terrain riding. The set reports a 40T chainring and a longer DUB crank spindle to accommodate both road and MTB bottom bracket standards. It’s sold without a BB, which provides flexibility to match your existing or preferred bottom bracket system. The 165 mm crank length is a common choice for riders seeking an efficient pedaling position while maintaining clearance on wider tires.
Features highlighted include a 40T ring, 1x simplicity, DUB spindle compatibility, and no BB included. The design emphasizes durable construction and reliable shifting performance, particularly useful for riders upgrading from a multi‑speed front derailleur or those adopting a cleaner 1x setup. It’s a strong option for riders prioritizing lightweight, simplified maintenance, and broad compatibility with a range of frames.
GANOPPER 32T Single Speed Crankset 1X MTB Crank Arm Set
The GANOPPER 32T 1X crankset is designed for single‑speed use and 1x mountain bike setups, featuring a 104 mm BCD and a 32T narrow‑wide chainring to improve chain retention on rough terrain. It lists a crankarm length of 170 mm and BB compatibility with 68 mm and 73 mm widths, making it adaptable to many road and cross frames that support 1x configurations. The design prioritizes stiffness and durability while maintaining a light overall weight suitable for modular upgrades on mixed-surface bikes.
Key points include: 32T chainring, 104 BCD, 170 mm arms, and 68/73 mm BB compatibility. The narrow‑wide chainring helps with chain retention on uneven pavement, while the 1x single‑speed setup reduces complexity and potential derailleur misalignment. This crankset is best suited for riders seeking a simple, rugged upgrade for road‑to‑gravel transitions and basic 1x builds.
microSHIFT Sword Black 1x Crankset
The microSHIFT Sword Black 1x crankset is designed for 9/10‑speed platforms with a 40T chainring and 110 mm asymmetrical BCD, which aids chain alignment and shift reliability. It uses a JIS square taper spindle interface, which is compatible with many older and mid‑range bottom brackets, and it lists an arm length of 170 mm. This crankset is positioned as a straightforward upgrade for riders building a light, efficient 1x system on road or gravel bikes that still rely on a square taper interface.
Notable features include 170 mm arms, 40T chainring, 110 BCD asymmetrical design, and a JIS square taper interface. It is particularly suitable for riders who want a budget‑friendly 1x upgrade without modifying their BB standards. The Sword line emphasizes compatibility and ease of installation, making it a practical option for versatile, all‑terrain riding.
BOLANY Mountain Bike Crankset MTB 1x Square Taper
The BOLANY 1x crankset is a rugged option built for single‑speed applications with a 104 BCD and a choice of chainrings in 32/34/36T. It features 170 mm crank arms and uses a square taper interface, aligning with older or budget‑friendly road and mountain bikes that can support 1x configurations. The design emphasizes durability and a lighter weight profile, making it suitable for riders who want a reliable upgrade without a complicated front derailleur system.
Key details include: 104 BCD, 170 mm arms, 32/34/36T options, and square taper compatibility. This crankset is particularly attractive for budget‑minded riders who want to maximize power transfer and chain retention on a 1x setup while preserving frame compatibility across a range of bikes used for commuting, light trails, and weekend rides.
Buying Guide
Crankset And Bottom Bracket Compatibility
Before purchasing, confirm your frame’s bottom bracket standards (68 mm or 73 mm shell width, plus spindle type). Some 1x cranksets use external or integrated BBs, while others rely on traditional JIS square taper interfaces. Check your frame’s crankarm length compatibility (typically 165–175 mm) to maintain a comfortable pedaling position and proper feel on descents and climbs.
Chainring Size And Gearing Range
40T is a common, versatile choice for road and light gravel, offering a good balance of acceleration and maintainable cadence on moderate grades. If you ride steeper terrain, consider a slightly larger ring or a 32T option paired with a compatible cassette. Narrow‑wide chainrings help with chain retention on rough surfaces, reducing the risk of drops. Ensure the crank’s BCD matches your preferred chainring sizes (e.g., 104 BCD is common for 40T rings).
Weight, Stiffness, And Durability
Higher stiffness improves power transfer and sprint response but may add weight. Aluminum cranksets provide a good balance of stiffness and cost, while some high‑end options use lighter alloys or advanced manufacturing. For mixed terrain, durability and reliable shifting trump marginal weight savings, especially on weekend rides and training miles.
Drivetrain Compatibility: 1x Vs. 2x
1x systems simplify setup and reduce maintenance, but you lose the wide gearing range of 2x setups. If you already own a wide‑range cassette or plan to ride mostly on flats and gradual hills, a 1x setup is practical. When upgrading, verify alignment with existing derailleurs and rear cassette. Some 1x cranksets pair with a variety of rear Cassettes from 9 to 11 speeds, but you may need to confirm the chainline and derailleur capacity with your frame.
Budget And Availability
Budget‑friendly cranksets deliver solid performance and easy maintenance, but they may lack some refinements found in premium lines. Availability varies by brand and model, with some systems offering more aftermarket compatibility than others. Consider future upgrades, such as a compatible front derailleur removal or a transition to higher‑speed rear cassettes, when budgeting for a 1x drivetrain upgrade.
Frame And Tire Considerations
Choose a crankset whose chainline suits your frame’s geometry and your tire width. Gravel and road bikes often benefit from a slightly wider chainline to avoid tire rub on the front triangle and to maintain smooth chain engagement on rough surfaces. If you use wider tires (38–40 mm), verify adequate clearance and a compatible chainring position to prevent contact with frame elements during heavy steering.
