You’ll find Shimano Claris is 8 speed and Shimano Dura-Ace is 11 speed. They both use a four-arm spider with uneven spacing between those arms, the idea being to provide strength and stiffness where it’s needed while keeping the weight low.The outer ring in both cases is aluminium/GFRP. The lower the number, the better. However, tolerance or gaps between chain pieces are only a part of the story, and the coatings and chain materials used are also likely responsible.According to CeramicSpeed’s data, the Eagle X01 chain (which sits at an average wattage of 6.27W with UFO V2 treatment) is approximately half a watt more efficient than the top-tier Eagle XX1 Gold chain.
That all said, Kerin’s data does suggest the Shimano Ultegra HG-701 11-speed chain offers better durability over the more expensive Dura-Ace HG-901 model.
As Kerin suggests, it’s these cheaper chains that are more likely to damage your drivetrain components through unexpected wear.
Why get a TT bike for? And those differences can be quite apparent, with thousands of kilometres separating the best and worst in terms of durability, and as much as a 4 watt (at 250W, 90rpm) difference in drag – not insignificant figures. They do this to save a little money, and they know most people won’t check their cassette.As we’ve just talked about, groupsets come in higher and lower varieties. If you’re sticking with Shimano 11-speed, I’d say it’s worth upgrading your Shimano chain to at least an Ultegra level, and if efficiency matters to you, then Dura-Ace is worth the extra.And perhaps the biggest takeaway from all of this testing is that no matter how durable a chain is, the lubricant you use will play the most critical role in drivetrain durability. Kerin subjected 31 models of chain to his motorised Tacx Neo torture chamber, keeping the lube (White Lightning Epic Ride, previously tested to be a poor and abrasive lube) and contamination controlled, all while measuring chain wear along the way. And similarly, SRAM’s Force AXS Flat Top chain is faster than the more expensive Red version. Without knowing what is wrong, it's hard to find the right fix. In theory both systems will handle a 34-tooth largest sprocket, but while we've heard of people persuading Tiagra to cope with a 36-tooth, we have direct experience of a long-arm 105 mech cheerfully shifting to a 40-tooth sprocket.The other major difference between the two groupsets is that the 105 brakes are considerably better than Tiagra ones. At least for Shimano, the efficiency does improve as you spend more. Premium chains from most brands feature slotted (or drilled) plates and hollow pins for weight savings.
