The HX 1501 Spline 1 is a high end all round trail wheel designed for all round E-MTB use, based on DT's renowned Spline 1 family the HX 1501 offers sub-2 KG weights with the supreme all-round durability that demanding E-MTB'ers requireE-MTB's are tough on wheels, really tough, not only is there the added weight and higher maximum drive torque but E-MTB riders tend to ride further and more frequently, this adds up to a real challenge for anyone looking to design a truly durable wheel for long term E-MTB useThe result is DT's mission Hybrid, the first wheel engineering project to look specifically at the challenges of heavy duty E-MTB use for wheelSo, what's new? Just the nice blue stickers? nothing could be farther from the truth!Hybrid ratchet hubs feature reinforced hub shells, oversized bearings and steel 24 tooth ratchets along with steel freehubs to prevent marking under extreme torqueThe rims have reinforced spoke beds to resist fatigue and handle high loads for long periods of timeThe straight pull spokes are custom made for Hybrid with an oversized 2.34 mm hub interface designed to protect one of the key points of stress on a wheel that's being used for E-MTBIn order for a wheel to pass as Hybrid certified in DT's inhouse testing lab it has to survive 50% more lifecycles, its spokes and rims have to endure 20% higher load tests and the bearings must be able to handle almost twice the maximum load of standard wheelWhilst intended for E-MTB use, the Hybrid range is also ideal for larger riders, bike packers or anyone looking for a really durable wheelset with a high weight limitRear wheels include both Shimano and SRAM XD freewheels for easy conversionWhen bought as a pair they will include tubeless rim tape and tubeless valvesSystem weight Limit: 150 KG
