SRAM’S RAIL 40 wheels have handled a shedload of punishment and – for the most part – survived unscathed.
Aimed at enduro/trail riders, they boast UST tubeless credentials, a 23mm internal rim width and 24 double butted, straight pull spokes per wheel, laced two-cross. They’re available to fit just about every axle dimension out there, and will take SRAM’s Torque Caps should your fork be compatible.We set our wheels up tubeless with Hutchinson Toro Hardskin tyres and, although the relatively narrow rims gave the 2.35in tyres a fairly rounded profile, had no issues with burping or unseating.
The Double Time freehub delivers consistent, rapid pick-up. The rear hub bearings have developed play quicker than expected, but SRAM assure us they’re aware of the problem and it’s now been dealt with.We’ve been impressed by just how well the rims have dealt with multiple tyre-bottoming rock strikes – they’re showing no signs of deformation and are still fairly straight. Hit really tight turns and there’s some flex, but not enough to detract from steering accuracy, so that’s no bad thing.
The 1,990g weight is OK for the price, but a slightly wider rim would be nice.
The RAILs have shrugged off months of abuse with relative ease. A slightly wider rim would be a plus though
