After winning the MTB World Championships in Champ\u00e9ry, the UCI Mountain Bike World Series in Lenzerheide was the first time we’d seen the world champion stripes on Jackson Goldstone\u2019s bike.<\/p>\n

Some interesting tech points were hiding on his Santa Cruz V10, including a prototype Fox 40 fork and new Shimano brake calipers that we believe are prototypes for an upcoming Saint groupset.<\/p>\n

While Goldstone showed good speed for the whole weekend, qualifying fourth on Saturday, an unfortunate crash in his race run cost him 8 seconds and resulted in a 22nd place.\u00a0<\/p>\n

We checked out the new world champion\u2019s bike in the pits to get a close-up look at the rainbow details.<\/p>\n

Fox 40 prototype

At the front of Goldstone\u2019s bike is a new Fox Factory 40 fork, which features stickers from the brand\u2019s RAD (Racing Application Development) programme.<\/p>\n

Unlike the Podium fork<\/a>, Fox has kept a traditional design for downhill racing<\/a>.<\/p>\n

\"JacksonThere were no clues on the top of the fork. Nick Clark \/ Our Media<\/p>\n

The crown looks to feature the generative architecture we\u2019ve seen on Fox\u2019s latest forks, including the new 36<\/a>, where the brand says it increased torsional stiffness by 20 per cent.<\/p>\n

At the top of the stanchion, it appears the fork is using a GRIP X2 damper, the same as that found on the current 40. However, we\u2019d expect the insides to be different from how it\u2019s labelled.<\/p>\n

New Shimano Saint brakes
\n\"JacksonIt would be cool if Shimano left these raw for the production model. Nick Clark \/ Our Media<\/p>\n

It\u2019s been nearly 13 years since Shimano last updated its Saint groupset, with many fearing the Japanese brand had forgotten its gravity-inspired riders.<\/p>\n

While we\u2019ve seen nothing of a new drivetrain, these chunky stoppers suggest Shimano has something in the works.<\/p>\n

The calipers are much larger than the recently released XTR 9220 brakes, closer to SRAM\u2019s Mavens<\/a>, hinting that these may be the big-power brakes many fans have been waiting for.<\/p>\n

\"JacksonThe current-generation Saint has been used with XTR levers by pros for a long time. Nick Clark \/ Our Media<\/p>\n

An XTR lever is used in conjunction with the caliper on Goldstone\u2019s bike, which we assume means the lever on upcoming Saint brakes may be the same.<\/p>\n

With SRAM showing a prototype DH AXS<\/a> at the weekend, could we see the big brands bringing updates to their downhill bikes<\/a> next year?<\/p>\n

Rainbow delight
\n\"JacksonSanta Cruz had the frame painted and shipped to Lenzerheide. Nick Clark \/ Our Media<\/p>\n

Goldstone took the stripes two weeks ago in Champ\u00e9ry, but we\u2019ve had to wait until now to see them.<\/p>\n

\"JacksonThere are details of the win throughout the bike. Nick Clark \/ Our Media<\/p>\n

The 21-year-old American’s team have gone to great lengths to make sure his victory is well celebrated across the bike, with the stripes featuring on various components.<\/p>\n

\"JacksonGoldstone appears to see the benefits of a tuned mass damper. Nick Clark \/ Our Media<\/p>\n

Goldstone\u2019s bike features other techy details, with his raceplate hiding a tuned mass damper.<\/p>\n

We\u2019ve seen a few riders experimenting with this, with the component said to reduce the amplitude and duration of vibrations down the trail.<\/p>\n

\"JacksonThis setup should reduce pedal kickback and reduce chain slap. Nick Clark \/ Our Media<\/p>\n

At the centre of the bike, an Ochain device<\/a> is used to reduce pedal kickback, while a STFU Trail chain damper is used to silence the chain.<\/p>\n

\"JacksonGoldstone’s mechanic says these hubs have been hand-painted. Nick Clark \/ Our Media<\/p>\n

Keeping the rainbow scheme together were these hand-painted Chris King hubs, which Goldstone\u2019s mechanic, Woody, has laced into Reserve DH rims with rainbow nipples.<\/p>\n
