Tire Giants Just Confirmed the 30.5" Wheel Is Real
An automotive supplier that builds clutches for Aston Martin just showed up with a downhill brake caliper that doesn’t look like a science project anymore. Raicam, based in Mondovì, Italy, has been circling mountain bike brakes for a couple of seasons now — levers on World Cup bikes, prototype calipers at trade shows, the slow creep every new brake brand goes through before anyone takes it seriously. This week, per Pinkbike’s tech coverage from the Lake Placid DH World Cup finale, that creep hit a real milestone: a production-looking Raicam caliper, not just a lever paired with someone else’s four-piston unit.
It’s a strange week for brake news. Lake Placid also gave us Shimano’s production-ready Saint spy shots, a brake backed by over a century of cycling-specific engineering. Raicam’s pitch is the opposite: zero cycling pedigree, decades of motorsport friction engineering instead. Brakes were the whole plot of this round, not the title race.
Quick Take
What it is An Aston Martin clutch and driveline supplier’s first full DH caliper, built on its own friction tech rather than licensed hydraulics Spotted Lake Placid DH World Cup finale, per Pinkbike’s tech coverage Who’s behind it Raicam, an Italian automotive OEM supplying clutches, flywheels, and torsional dampers to Aston Martin Based Mondovì, Italy — brakes manufactured in-house, not outsourced Existing lineup RG Gravity (Enduro/DH/eMTB), RXO (Trail/Enduro crossover), RXC (XC/down-country) — each in Racing, Factory, and Performance tiers Top lever detail Factory-tier lever uses a micro-bearing pivot; lower tiers run a bushing Price context Raicam’s existing RGR Factory trail/enduro brake runs roughly €800/pair — this new DH caliper has no price or ship date yet Best for Riders curious about the next brand trying to break the Shimano/SRAM/Hope lock on gravity braking Skip if You need a brake you can buy today — this is still a spy shot, not a product launch
Yes, and it’s less strange than it sounds once you look at what Raicam already does. The company has spent decades as an OE supplier of friction materials and driveline components to the automotive and motorsport world — clutches, flywheels, torsional dampers. Raicam’s own announcement about its Aston Martin relationship confirms the long-running OEM supply deal, and per Bikerumor’s reporting on Raicam’s MTB entry, that same hydraulic and friction know-how is what’s getting repurposed into bike brakes.
That’s not nothing. Friction management and heat dissipation under sustained load is Raicam’s actual day job, just normally applied to something with four wheels and a lot more mass than a mountain bike. Whether that translates cleanly to a bike lever and caliper is a separate question — braking a 1,500kg car and braking a 180-pound rider on a 40-pound bike are not the same engineering problem, even if the underlying friction physics overlap. But it’s a more credible entry point than, say, a random component startup with no prior hydraulics experience.
Before this week, Raicam’s MTB presence was three lines, each split into Racing, Factory, and Performance tiers:
All three lines use 2- or 4-piston hydraulic disc calipers depending on tier and discipline, and — per Bikerumor’s coverage — every brake in the lineup is made in Italy, not farmed out to a contract factory elsewhere. The top-spec Factory lever is the one detail worth remembering if you’re cross-shopping tiers: it runs a micro-bearing pivot instead of the bushing pivot used on the Racing and Performance versions below it. Small detail, but it’s the kind of thing that shows up as lever feel the first time you pull it, not in a spec sheet.
None of that is DH-specific hardware, though. Through most of this season, what showed up on World Cup bikes was Raicam levers — paired with other brands’ calipers, not Raicam’s own.
This is the part of the story that makes “spotted at Lake Placid” more than a one-off photo. Raicam levers have turned up at multiple 2026 World Cup DH rounds this year, mixed and matched with calipers from other manufacturers — the same way pro mechanics have run Shimano Saint calipers with XTR levers for years when the parts happen to bolt together and work. A lever showing up alone isn’t much of a story. It usually means a sponsored rider is testing ergonomics while the actual braking hardware stays whatever’s already proven.
Trace it back far enough and the pattern is less “prototype gets cleaner” and more “borrowed parts get replaced.” Pinkbike’s own Tech Randoms coverage of the 2025 Andorra DH World Cup spotted a Santa Cruz V10 running a Raicam lever paired with a SRAM Maven caliper — someone else’s stopping power, Raicam hardware only at the hand. A year and a Lake Placid round later, the caliper underneath that lever is finally Raicam’s own. That’s a different story than a single brake maturing through rough drafts: it’s a company swapping out the one part it didn’t make yet.
Here’s the thing that makes this week specifically interesting instead of just another spy shot: gravity braking has been a two-brand conversation for years. Current Saint is the value pick in our brake shootout, and the next-gen version is closing in on retail. The SRAM Maven B1 sits above it on price — $249/wheel for the Silver version, $349/wheel for Ultimate, per our own testing — and at the top of the power ceiling most riders actually chase. Raicam’s existing RGR Factory brake already lands north of that Maven Ultimate number on a per-end basis, before a DH-specific caliper with its own tooling and piston count even gets priced. Hope, Trickstuff, and a handful of boutique brands fill in around the edges, but nobody’s seriously threatened the Shimano/SRAM duopoly on DH-specific hardware in years.
A new caliper from a company with zero bike-brake brand recognition doesn’t threaten that lock this week, or probably this season. But it’s one more data point in a pattern worth watching: automotive and motorsport suppliers looking at mountain bike brakes as an adjacent market worth entering, the same way we’ve seen with Pirelli’s return to MTB tires. When a company that already solves braking and friction problems for a living decides bikes are worth the R&D spend, that’s different from a startup bootstrapping hydraulics from zero.
Too early to say with any honesty. Raicam’s existing RGR Factory brake — the trail/enduro-focused model already on the market — gives some signal: 4-piston caliper, roughly €800 per pair with pads, rotors, and mineral oil included, and reviewers who’ve actually bled and bedded them in note solid power on par with Shimano XTR, though without quite the lever refinement of Hope’s Tech4 V4 or the premium feel of Trickstuff. That’s a reasonable starting point for a brand two or three product cycles into bike brakes. It’s not a brand beating the established players yet.
The DH-specific caliper spotted at Lake Placid is a different piece of hardware entirely, built for a harder braking environment than anything in Raicam’s current catalog. No pricing, no piston size, no rotor spec, nothing beyond “it exists and looks finished.” Judging DH performance off a photo at a World Cup is exactly the kind of claim this site won’t make.
Riders who track new brake brands before they’re mainstream. If you were early on Hope or Trickstuff before they had real retail presence, Raicam is the current version of that bet — unproven, but backed by real hydraulics experience rather than a crowdfunding campaign.
Anyone curious why non-cycling companies keep entering MTB components. Raicam joins a growing list of automotive and outdoor-adjacent suppliers treating mountain bikes as a legitimate R&D target, not a side hustle.
Readers already following the Saint spy-shot story. Lake Placid turned into a two-brake story this week. Worth tracking both threads together since they’re both pointing at the same broader shift: 2027 could see more gravity brake competition than the sport’s had in a decade.
Anyone brake shopping this week. Current Raicam products are trail/enduro-focused, not DH-rated, and the DH caliper spotted at Lake Placid has no release date, price, or spec sheet attached to it.
Riders who want brand pedigree before they buy. Raicam’s automotive credentials are real, but zero of that experience has been proven on a World Cup-level DH run yet. That’s a different bar than supplying clutches to Aston Martin.
Strip away the brand name and this is a clutch-and-driveline supplier deciding bikes are worth the R&D line item, then showing up a year later with its own caliper instead of someone else’s bolted to its lever. That doesn’t make Raicam a threat to Shimano or SRAM yet. It makes them a brand worth bookmarking, backed by friction and hydraulics experience most MTB-only brake startups don’t have on day one. The existing RGR and RXC lines are already real, buyable products with a sensible tier structure — Racing, Factory, Performance, with the bearing-pivot lever reserved for the top spec. The DH caliper is the piece that was missing, and it just showed up looking finished instead of experimental. An Aston Martin supplier’s name on a World Cup brake is a curiosity until someone actually bleeds one and beds it in.
