SLX – for those exploring their mountain bike calling
Like DEORE XT, the new SLX M7100 series also features Shimano’s groundbreaking 12-speed MICRO SPLINE cassette with either a 10-45T or 10-51T range, 1x12 or 2x12 cranksets, a dedicated SLX-level 12-speed chain, 2-piston or 4-piston brakes, fully adjustable ISPEC-EV shifters, optimized front and rear derailleurs and 12-speed ready hubsets, bringing premium technologies to those discovering true mountain biking.
Cranksets: The new SLX 1x12 crankset features HOLLOWTECH II technology with an integrated bottom bracket axle and hollow crank arms. Chainrings come with a Dynamic Chain Engagement+ tooth profile, which, with its narrow/wide teeth, aids chain retention, smoothness and quietness of the drivetrain. To securely and quickly mount the chainring the crank is equipped with a direct mount system. The crankset comes with 30T, 32T and 34T chainring options, interchangeable with XTR and DEORE XT rings, and has crank length options of 165 mm, 170 mm and 175 mm.
SLX M7100 cranksets are available in three chain lines:
52mm (FC-M7100-1) for Over Lock-Nut Dimensions (O.L.D.) of 142mm or 148mm to give the narrowest 172mm Q-factor
55mm (FC-M7120-1) for an O.L.D. of 148mm for wider tyre and frame clearance (Q-factor 178mm)
56.5mm (FC-M7130-1) for an O.L.D. of 157mm and a Q-factor of 181mm
Crankset weights: FC-M7100-1: 631g, FC-M7120-1: 638g, FC-M7130-1: 656g (all 32T; 175mm, w/o BB).
The SLX 2x12 HOLLOWTECH II 36-26T crankset offers the ultimate range when matched with the 10-45T cassette, maximizing your possibilities on all sorts of terrain while maintaining small gear steps.
Two 2x cranksets are available, both featuring a 2-bolt system for fixing the left side crank arm in place on the spindle. Much like DEORE XT, the FC-M7100-2 crankset has a 142mm O.L.D. for chain lines of 48.8mm and a Q-factor of 172mm. The FC-M7120-B2 crankset has a 148mm O.L.D. for chain lines of 51.8mm and a Q-factor of 178mm.
Weight for the FC-M7120-B2 (36-26T, 175mm, w/o BB) is 682g and for the FC-M7100-2 (36-26T, 175mm, w/o BB) is 674g.
Cassette: SLX 12-speed cassettes come with the MICRO SPLINE fitting system and are available in a 10-45T option for small gear steps or a 10-51T option for maximum range. Both cassettes also feature HYPERGLIDE+, allowing for quick up and downshifts and an extremely quiet drivetrain. The cassettes have an aluminum spider to house eleven steel sprockets and one aluminum sprocket for the best balance of durability, weight and riding styles. The CS-M7100-12 10-51T cassette weighs 534g and the 10-45T option weighs 513g.
Chain: The SLX new 12-speed HG chain has been redesigned with an extended inner plate to improve chain engagement and retention and comes with SIL-TEC roller link plates for smoother running and more durability in all conditions. The CN-M7100 chain (113 links + Quick Link) weighs 252g.
Derailleurs: Coming in either single (RD-M7100-SGS) or double (RD-M7120-SGS) chainring variants, the SLX rear derailleur enables precise and quick shifting over that huge 12-speed gear range. Both derailleurs feature SHIMANO SHADOW RD+ positioning as well as bump stoppers and 13T pulley wheels to make rides quieter and more enjoyable. Rear derailleurs weights: RD-M7100-SGS: 316g, RD-M7120-SGS: 322g.
The SLX front derailleur comes in one specification for both 48.8mm & 51.8mm chain lines but is available for D-type, E-type or M-type mountings. Front derailleur weights: FD-M7100-D: 135g, FD-M7100-E: 166g, FD-M7100-M: 114g.
Shifters: With side adjustment and rotational adjustment options the ISPEC-EV shifters, which bolt neatly to the brake lever, offer solutions for tailoring the riding feel. For riders using a 2x12 set-up, a MONO lever (SL-M7100-IL) on the left shifts the front derailleur both up and down with an extremely light and precise action. SLX M7100 shifters are also available in a clamp band version.
Shifter weights: SL-M7100-IR: 121g, SL-M7100-IL: 73g.
Brakes: SLX brakes calipers are available in an XC-specific 2-piston version or a Trail/Enduro 4-piston version. The 2-piston version shares the same design as the previous version, which means the previous SLX-level G02S/J02A resin brake pads or G04S/J04C metal pads brake pads are compatible, whereas the 4-piston version is a new completely new construction drawn from the XTR M9100 design, using D03S (resin) or D02S (metal) brake pads pad (compatible also with N03A and NO4C finned pads).
The SLX brake levers work with both the XC and Trail/Enduro calipers and come equipped with Shimano’s Servo wave system for quicker engagement, improved power and a shorter free stroke. The brake levers are now angled in two positions against the handlebar for a stiffer brake sensation. The levers also feature a reach adjust dial for simple brake tune-ups on the trail.
XC style brake kits (BR-M7100-BL-M7100) with rotors (160 mm SM-RT70) and brake pads weigh 425g and the Enduro style brake kits (BR-M7120-BL-M7100) weigh 444g including rotors and pads.
Rotors: The SLX-level ICE TECHNOLOGIES rotors (SM-RT70) are designed to cool rapidly thanks to a sandwiched aluminum core, fused in a durable steel outer layer, resulting in consistent brake performance and longer lasting brake pads. Sizes available are 140mm (121g), 160mm (133g), 180mm (159g) and 203mm (193g).
Hubs: Individual SLX front hubs and rear FREEHUBs are available in widths of 100mm and 142mm, 110mm and 148mm, or 157mm. The FREEHUB (FH-M7110) features a cassette body with Shimano’s MICRO SPLINE design. Hub weights: HB-M7110: 142g, HB-M7110-B: 147g, FH-M7110: 350g, FH-M7110-B: 354g, FH-M7130-B: 359g.
Summing up a huge range of options it’s clear that the new DEORE XT M8100 series provides high performance features for today’s demanding and adventurous mountain bikers, whereas the SLX M7100 series, sharing the same DNA, draws on this inspiration to bring quality performance to those discovering the fun of mountain biking.
Henry Bosch, Shimano Europe MTB product coordinator: “Whilst speed, focus and control was the mantra we lived by during the XTR development, we needed to widen that for DEORE XT and SLX. We thought a lot about how and why people ride mountain bikes. For us the answer was in making a set of components in the right grade and specification to match the competitive ambitions, the adventurous riding styles and the performance quality of mountain bikers across the globe, above all making sure that riders receive durable performance to have as much fun as possible.”
SHIMANO SLX components will be available from mid July.
