Atomlab’s SL alloy handlebars switch from 6000-series to 7000-series alloy, dropping the weight to about 260g and becoming more fitting of the SL moniker. They have a 25mm rise, 4° upsweep and 9° back sweep. Width is 760mm. There’s also a new 195g Carbon SL (red), which will only be a 31.8 with 15mm rise, 6° upsweep and 9° back sweep.

They’ve added a new 31.8 bar alongside the original 35mm clamp size, and the stems get reducers if you wanna run the thinner bar.

Check out pedals, hubs, cogs and gears below…


The reducer fits around the 31.8 bar, then clamps into the 35mm ID stems. Note the difference between the 31.8 and 35 bars side by side.


The new SL flat pedal gets a longer axle and wider platform than their other pedals, and it gets a bit more machining, too. It has 10 pins per side that thread in from the front sides and don’t pass all the way through. Weight is 360g for the pair. Body is 6000-series alloy, spindle is cromoly with a cartridge bearing and DU bushing.


The 102 hubs and SL Trail wheels get a new Crimson red ano color, which is matched by most of the rest of their line, including the new parts. They’re jumping on the narrow/wide chainring and oversized cog bandwagon, but the benefit here is they’re color matched to the wheels and other parts. The 40 and 42 tooth cogs comes with a steel 16t cog to replace the 15 and 17, then the large cog fits against the back of the cassette.


Boost hubs are coming, too, which will get CenterLock and 6-bolt options and their 102 points of engagement freehub mechanism.


Speaking of hubs, their DHR hub, which is made specifically to fit a 7-speed cassette without any spacers, is shipping.


It works nicely on their Corsair DH bike, which is also now available.


The Corsair Revo enduro bike we saw at Eurobike last fall gets a tweaked graphic plan, changing from the glossy blue graphics to a more subdued matte blue.

Those SL ‘totally not Hope F20s’ look nice, except Hope already make the F20 themselves in the UK, presumably that pedal’s not coming over here.

Hope asks an awful lot for the F20, considering what it is, so I won’t complain about another option, if it’s priced more competitively.

The SL pedal will be $135. We made the first extruded CNC pedal about 17 years ago…
