Bike Check: Adam Brayton's Nukeproof Giga 290 Carbon

May 29, 2021
by Nick Bentley  


During the Gravity Events Downhill Series round 1, I managed to catch up with Adam Brayton and have a chat to him about his shiny, new Nukeproof Giga 290 Carbon. It may seem like Adam brought a knife to a gun fight using an enduro bike for a DH event, and maybe a few years ago that might be true, but now with the new breed of long travel enduro bikes that's no longer the case. This is something I brought up with Adam and asked why he picked this bike to use over his Nukeproof Dissent 290. He said he felt that with the pedally sections on the track and the way that the Giga rides, he felt it was the tool for the job. This, to me, is something I think has some merit for 90% of the UK downhill races where there isn't crazy elevation and quite often large pedally sections thrown in so a long travel enduro bike (or as Nukeproof put it Super Enduro bike) starts to make a lot of sense.

Adam's Giga is obviously a complete custom build with plenty of Hope's CNC machined loveliness scattered all over the bike. His plan to use his Giga proved to be a smart one as he took home 4th place in a stacked UK Elite field at Gravity Events downhill series round 1.

Ad Brayton was out with the number one board this weekend and on the enduro bike pushing hard as always.

Adam was running some interesting frame protection in the form of camouflage tape. A bit of a departure from the normal clear helicopter tape or invisiframe kit.

bigquotesI thought the Giga would be well suited to the track. It was a lot of fun to ride and I can’t wait to race some enduros on it this season!Adam Brayton

The Giga 290 Carbon, is Nukeproof's new "super" enduro bike with 170mm of rear travel when running 29" wheels. The Giga is a UD Carbon Fibre frame with an adjustable main pivot, internally piped cable routing, ISCG 05 mounts, threaded 73mm BB and Boost 148mm rear axle spacing. There is 3D contoured rubber frame protection to be found in all the normal locations around the chainstay and under the bottom bracket. Interestingly, there is a factory fitted clear paint protection kit fitted to all Giga's as standard and Adam's is no different. Adam's Giga is in gloss black, which is not available to buy right now, although with bike availability as it is they're pretty hard to buy in any colour. If you want more information on the Nukeproof Giga, check out Mike Kazimer's first ride review here

Adam is running a full complement of Fox suspension and dropper post. Starting with the forks, these are a Fox 38 Float, Factory Series fork, with 38mm Kashima coated stanchions offset at 44mm, which are housing a Grip 2 Damper, running 180mm of travel.

The rear travel is taken care of by a Fox Float X2, Factory Series shock with a Kashima coating. The X2 has the 2 Position lever to allow for locking out on long fire road climbs. Adam is still running the Nukeproof custom tune in the X2 that came with the bike, the same as anyone else who buys a Giga, the X2 is a 205x60mm size with a Trunnion mount. The Fox Transfer dropper seat post is again the factory version which is again Kashima coated and is 170mm in travel.
photo
The Giga's internal cable routing comes down the downtube and out under the shock before going back in to the seat stays. To keep his bike running super quiet, Adam has put neoprene foam tubing around the brake line and rear gear cable housing to stop them making noise as they knock against the shock.

Adam had the privilege of running the number one plate at round one of the Gravity Events series. This was attached to his full Renthal cockpit set up with Adam running a Renthal carbon fatbar with a 20mm rise and cut down to 760mm wide mounted to a Renthal Apex 35 stem which is 40mm long. All finished off with a set of Renthal Lock-On Traction Grips in black. The camo tape has made another appearance protecting the Renthal bars from rubbing from the cable ties used to hold the number board to the bike.

The cockpit is topped off by the Nukeproof skull top cap.

photo
Sat on top of the Fox Transfer seat post is a Nukeproof Sam Hill Enduro Saddle Oil Slick that has a low stack height, approx. 8mm lower than standard rails. This means you aren’t using unnecessary space which could be better utilised with a longer dropper post.

photo
Hope still reserve this special colour for its factory riders and some of its complete build bikes.

Braking is taken care of by Hope's popular Tech 3 E4 brake front and rear. The 4 piston brakes are a CNC machined one-piece design machined totally in-house by hope in Barnoldswick, Lancashire. Adam has fitted Hope's 200mm, floating and vented rotors front and back. There are some nice colour touches on Adam's set up with the orange screws in both of the tech 3 lever adjusters. There are also matching orange washers on the caliper bolts just to tie it all in.

Adam is running Hope's Evo Crankset with 170mm long crank arms and a spiderless Hope narrow wide 32 tooth chainring. Mounted to the ISCG 05 mounts on the Giga frame is a Hope Slick Guide Short chainguide for added security from dropping chains when you're riding as hard as Adam is known for. Adam is running Crankbrothers Mallet clipless pedals

photo

Adam is running a SRAM 10-51 GX eagle cassette, chain, rear mech and shifter.

Wheel-wise Adam has a set of 29" Hope Fortus 30 wheels with Pro 4 hubs front and back. The Hope Fortus rims are a Welded 6061 T6 Aluminium rim with eyelets, 30mm wide rim and are laced to a set of Hope Pro 4 hubs with 32 Black Sapim Race stainless steel double butted spokes built with silver brass nipples. Adam is running Cushcore inserts front and rear along with Double Down Maxxis tyres which is another indicator this bike is built to be ridden hard. Tyre-wise there is a Maxxis Minion DHF that is 2.5" wide and on the rear is a Maxxis Dissector that is 2.4" wide. There is no denying this bike is set up to take the hits, that's for sure.

Thanks to Ad for spending the time between practice and his race run for me to do this bike check.

 What’s that wire thing coming from the shifter?

 Maybe a battery-free prototype? What powers it??

 it's an antenna extension, so he can operate his shifter from up to a half mile away

 @alexdeich: Close, so he can operate other racer’s derailleurs from 1/2 a mile away.

 Look, someone has to say it, it looks like a Santa Cruz

 The shock placement is similar but the front triangle on a Santa Cruz bike is totally different.

 It’s a big single pivot. Doesn’t look like a SC to me.

 More like a Nukeproof Scalp, dissent which where out way before a current Santa Cruz if you have a look ;-)

 Sort of. This has a proper steep seat angle, unlike santa cruz, that with the exception of the bullet, have slack actual seat angles. Can’t ride a SC with long legs - you end up sat over the rear axle.

 everytime i see comments like that, i have to ask myself if people are blind on both eyes or just dumb

 You mean Santa Cruz looks like this. In the enduro world Nukeproof are dominating Smile . My main bike will be a Santa Cruz Megatower cc when i build it up. Moving over from a NP Mega 290 factory.

 Dear Nukeproof,

It's a really nice bike but why is the beautiful saddle (designwise and shape, color is debatable ) not available for sale?

I would gladly spend my 70 Euros on this Spesh lookalike saddle rather than give them my money because I know Nukeproof gear performs equal or better, looks cooler and pays Sam Hills wage, which is an underrated argument.

Let him ride til 50, so fluid and effortless, a perfect example for riders young and old.

So please let me buy this Nukeproof Sam Hill Enduro Saddle, would you?

Thanks Nukeproof

 It’s not about needed. If I was a pro I would want the best and lightest thing I could get. Just proves he doesn’t wanna be as competitive as possible. @Clifflane3:
  • 12 0
 @freeridejerk888: he's not on a full factory team anymore. He's "Supported" by Nukeproof, Maxxis, Hope and probably a few others. But, as @jamesbriancrilly said, either he or his team manager (if he still has one, I can't recall), is buying some of their gear out of their personal budget. I'm sure blowing thru several xx1 eagle derailleur every season is gonna add up real quick.

 @Trudeez: yeah and it goes to prove that the mid-tier stuff is really good anyway. Good enough to be competitive on.

 Exactly. why not go with the best and the lightest when you're a Pro & have the #1 plate.

 "His plan to use his Giga proved to be a smart one as he took home 4th place in a stacked UK Elite field at Gravity Events downhill series round 1." He got 4th.

 "Adam is still running the Nukeproof custom tune in the X2 that came with the bike, the same as anyone else who buys a Giga"
So basically a one off custom tune then....
  • 5 1
 Most OE bikes have a custom tuned shock for that frame. After market shocks are the standard ones.

 Took me a second to get it, but it was a good one.

 Yep, totally missed it as a joke. Probably because I've seen at least one other Giga. Two is a crowd these days.
  • 3 0
 There isn't really a custom tune for most X2s. The advantage to a twin tube shock is that you don't need a custom mid-valve tune except in extreme situations.

99% of all fox X2 platform shocks have the exact same shim stack.

 Hope rims are the only product hope don’t make themselves. And it shows - weigh a tonne and not that good.

Way better to build some hope pro4s onto Dtswiss rims

 Build on other hubs. Only reason to use hope is because you want something shiny. @Richt2000:

 Agree. I run dtwiss hubs and rims these days, but when I ran hope pro2s evos and then pro4s evos never had any issues, super reliable. Just don’t like their rims.....
