Tech Randoms Part I: Fort William DH World Cup 2024

The most recent Gamux Sego DH prototype is now under a veil of mystery. We are told the veil is not covering a new shock, or any changes to the kinematic, or indeed anything structural at all. I think we will have to take that one with a pinch of salt. I will say, Gamux work with Manitou for suspension, and we are yet to see a coil shock from them…

The first winner of World Cup Downhill race (in 2024) on board a Gates Carbon Drive will be awarded a €100k “Belted Purse”

Gamux machine the Sego DH frame from 7075 T6 aluminum, and then bond in carbon fiber sections to fine tune stiffness

The Gamux was home to a new tire from Schwalbe, as indicated by the “First Ride” hot patch

The tread pattern is distinct from anything in Schwalbe’s current lineup, but it certainly has its similarities with a certain Maxxis tire beginning with ‘A’

Polygon looks to make a comeback in downhill with the new Collossus DH, to be raced this weekend by Douglas Vieira

It runs the same IFS suspension platform as the Collossus Enduro bike. It can be setup as a mullet or full 29″ with the geometry correcting flip-chip in the rear, there’s a flip-chip at the lower shock mount that adjusts the BB height, and the headset has 1.5″ cups that allow for use of aftermarket angle and reach adjustment headsets.

The size large has 480mm reach and a 445mm chainstay length

Vieira’s Polygon was home to a prototype from Kenda

It also has its similarities with aforementioned Maxxis tire

It looks as though Canyon have a new Sender, full details of which we are not yet privy to. We can discern it will be a not-inconsiderable departure from the current linkage-driven four-bar design, now home to a rear pivot that sits concentric to the rear axle – as opposed to the Horst pivot seen on the current bike. We’ll be keeping our eyes peeled for a closer look at this one.

Dakotah Norton’s is running a 75mm rise bar on his Mondraker Summum prototype – full bike check to come

He was previously experiencing chinbar clearance issues when running a 40mm rise bar with 35mm worth of spacers underneath (he was smacking the chinbar off the stem)

Dakotah (and many other e*Thirteen sponsored athletes) is running the new Sidekick hub, the internals of which are yet to be revealed

It’s a completely silent hub, but that’s not the interesting bit. Rumor has it that some kind of “floating” mechanism inside allows it to reduce pedal kickback (a bit like an OChain, without the need for any electronic actuation. It is entirely mechanical.

The floating brake arm on the Cube Two15 DH Bike reduces anti-rise from 105% to just 18%, helping to keep the bike higher in its travel under rear braking

Finn Iles’ Specialized Demo prototype is said to have a new shock from Ohlins, though we weren’t permitted a peek under that Brutalist cover

Three electronic buttons on the bar switch it through different modes – the top cap serves as a reminder of which color does what. Oh, there’s a new 3D printed brake lever from Magura on there, too.
