More than likely, if you’re looking for new wheels from RaceFace the new Turbine R wheels will be your first choice. As much as we’d all like to run the best parts all the time though, if you’re looking for more affordable wheels RaceFace has you covered. The new Aeffect SL, R, and Plus wheels follow suit with the rest of their Aeffect product offering a great blend of performance and value. The wheels should check a lot of boxes for most riders with 27.5 and 29″ options in most versions, though the Plus will only be offered in 27.5″. Running a 40mm internal width, the Aeffect Plus is ready for adventure…

Also built with the same straight pull hubs and double butted spokes with brass nipples, weights for the SLs are listed as 1710g for 27.5″ and 1790g for 29″.

The Turbine R 35 stem is new to the line, but RaceFace tells us it’s essentially a rebranded Easton Haven. Which is good since that’s a very popular stem. The 7075 aluminum Turbine R is meant for 35mm bars and will be offered in 32, 40, 50, 60, and 70mm lengths with zero rise, a 42mm stack height, and a claimed weight of 138g for the 50mm.

    Jeb: what comparable forged stem is lighter, stronger and cheaper?
    The forged stems i see are a little cheaper, possibly stronger, but definitley not ligher.

    Syncros XM1.5 FR 35.0, half the price, stronger (look up bent haven stem on google) and a smidge lighter. This is a direct comaprison to another 35mm stem. If we were comparing to 31.8 stems the difference is much bigger with more options.

    I am guessing that since not a single word was wasted on the hub internals, that it’s the same (tired) pawl design as the Vault hub on the R wheels?

    I get that all these companies want to be part of the wheel game, but man, how many so-so hub options do we really need?

    If you want my money you better get busy with something other than pawls. The crappy ratchet set you can get from Harbor Freight for 15.99 uses pawls.

      In terms of reliability, manufacturability, serviceability, and weight it is hard to beat a ratchet set up. There are of course other options in design, but they all have strikes against them. But I’ll still be picking up a set of Stealth or Onyx hubs for my next build. Just for the silence.

      A pawl system is proven to work very well if designed correctly. If you have been in the industry long enough you will see broken teeth on DT ratchet, and King splines, everything can break. The I9 and Vault hubs that use pawl systems are far from tired as they work extremely well and have faster engagement than the King which is the gold standard. the sprag cluches have been around for a long time tested and tried by King and Lew back in the early 90 but abandon due to the ability for them to fail at higher loads. There are riders that will have zero problems with those hub but bigger riders with lots of power have been known to break them. Plus they are about 100g heavier than other systems.

        I’ve broken every pawl hub I’ve ever used in short order over 30 years of mountain biking. I haven’t tried an I9 hub but that’s about it. I’ve never broken a DT Swiss hub and I currently beating on six DT 240s and 350 hubs. I’m guessing that they may fail when there is a bunch of grit inside causing poor engagement but that’s about it. I have two King hubs which have been ok but I still get popping out of them once in a while when they fail to engage properly (both are quite new and spotless inside).

        Sprague clutch hubs feel like poop to me. They have a mushy feel with a bit of kickback on rough climbs. Most recently I tried a Nobl (modified Onyx) wheelset and was put off by the vague feel. The silent coasting was pretty rad though.
