Can't wait for Scott to release the first one piece handlebar/fork steerer so we don't have to worry about stems anymore !

One day powder bed fusion manufacturing will be so good that Scott will be able to manufacture an entire bicycle as a single part.  Maybe.

You are a professional road rider that believes it will be more aero..

I'm on a L 2018 Smuggler which came with a 40mm stem and 20mm rise (7° backsweep) bars. 

I'm now on 50mm rise, 10° backsweep bars on a 60mm stem. The increase in backsweep which is heaven for my wrists did result in a more cramped feeling "reach" hence the 60mm stem. 

Stem height is probably 5mm lower than what it was originally.

Oh you have to change out your headset bearings? Thats stupid just throw the bike away and buy a whole new one 😃

Yeah but they can just melt it down and print a new one

What does running a stem that 'matches the fork offset' have anything to do with anything? This is one of the most WTF claims I have heard regarding bikes and bike fits.

Where in relation to this offset is the tyre to ground contact patch? How does the handlebar to patch relation change relative to wheel size? Fork axle to crown? Dynamic sag? Travel position? Head angle?!

Most importantly, what does the position you attach your handlebars to have anything to do with riding dynamics when you can have multiples of 10 mm difference in handlebar setback (effective reach or whatever you want to call it) depending on handlebar geometry.

To get into a similar position running a 55 mm rise handlebar that I had only in 12/8° sweep resulted in me having to run a 70 mm stem to be in roughly the same position fore-aft as I was with a more normal 8/5° sweep handlebar on a 40 mm stem. Because the bars are made by having the backsweep swept BACK, they do not come forward and then back to have the same relative clamping to hand position.

Commenting on stem lengths should REALLY include handlebar geometry and also roll to have even a smidge of comparability between setups.

My opinion is that several people, including racers have tried it, and it led to crashes. I don't know the engineering or numbers behind it, and I don't need to, riders seem to crash more on shorter stems, I personally feel more comfortable on a 42.5mm stem than a 35mm stem. If it ain't broke, don't fix it.

Racers have crashed on short stems because they haven't used them with long chainstays. If you feel more comfortable on a 42,5mm stem then stick with that. I've tested -10, 10, 17 and 20mm in the last decade and I've settled on 20mm. My bike has 474mm chainstays and I have loads of front end grip.

Its a good looking bike. 

And under Colognes it sure looks fast, given that hes coming from the Commencal, which everyone seems to think is the fastest bike on the circuit right now.   

It also appears to the the same "2008 demo" suspension design as the "new" Nukeproof haha.

Coulanges, the name you are looking for is Coulanges. He rides a bike for a living. 

Colognes. You wear those on the body to smell better. Know your French.

It's actually closer in suspension design to the Supreme v5 in that it's an upper and lower link connected by a tie rod. The shock on the new Gambler appears to be driven by the lower link rather than the upper link.

Didn’t mondraker go down this road years ago only to become more moderate? And if you look at race results of the most recent people using the super short stem theory - cough *gamux, you’ll see it’s not exactly the most successful thing in the pits. 

Seems a strange design ethos.. to position myself further backwards to correct my weight bias that’s happened due to an extremely long chainstay I have designed; I then needed to utilise a novel stem to shorten everything up and position myself centrally! 
Or am I reading it incorrectly?

Counterpoint - Back in 2012 Brook went back to a normal stem and won a world cup after being on the short one most of the season

Only if it lives up to the Scott name, by including a remote lockout and headset cable routing

fork in the picture is a fox 40 though.

Am I the only one who thinks the red giga looks weird? Almost like reverse mullet. Hope I'm not having a stroke or something.

that Megafly is just a rebadged Ridley Raft. I guess that there will be a fair amount of repurposing from BCF

Went to check but they’ve taken them off the site. If you search on DuckDuckGo for Nukeproof “reactor crb” or any name of bike it will come up with the page but no geometry anymore and the menu pages that show all the bikes are no longerIMG 7865

There were geo charts when I looked, but I didn't memorise them. The Kilowatt had a 445mm rear centre across all sizes and I think a 64.5HTA, with a reach about 475 in large. I'm assuming the Reactor would be similar with a shorter RC as it has no motor.

 

They did also have the Megawatt carbon with the SRAM motor up on the website as well, so it seems like a mix of the older designs (Mega, Scout), bikes they had in the works (Reactor v2 and Giga v2) and ones borrowed from BCFs other brands (Megafly)

See that alot on road bikes and Santa Cruz... Carbon frames and cheap build kits.. Because somehow the Carbon frame will cover up the performance of the lower tier parts...

Manufacturer wise it should make sense as they buy the gear and "make" the frame so the margins should be higher. Problem is most of the brands also buy the frames 😂
