Amaury Pierron has shared what looks to be a new short travel bike from Commencal called the Tempo.
The race season isn't over for Amaury Pierron just yet, as he will be trying out some XC racing this weekend on what appears to be a fresh bike from Commencal. We have seen Cecile Ravanel running a short travel Commencal for some time, but the new bike spotted here looks far closer to production and even is badged with the name 'Tempo.'
The bike seen in Amaury's social media post looks to use a similar suspension setup to the new
Commencal prototype enduro bike that uses a short-link four-bar layout with a rigid rear triangle is connected to the mainframe via two short links. The front triangle looks very different from Commencal's current range of bikes with slimmer-looking tubes that most likely save some weight. Unfortunately it also looks like the rear brake line and dropper housing are routed through the headset, a trend that seems to be catching on for some unknown reason. Fingers crossed that changes for the production model.
Commencal has taken a pretty strong stance against carbon fiber bikes in the past, so it's not surprising to see that this bike is constructed from aluminum. Given that modern XC bikes are normally made from carbon it will be interesting to see how light Commencal are able to make an alloy frame, and if it could be competitive at World Cups against other non-metal race bikes.
We have reached out to Commencal for comment and will update this if we hear back.
Bike companies: No one likes that shit. Not even Pinkbike, who has a tendency to make excuses to try to defend stupid 'new standards' that don't need to exist.
“Use my PITA headsets or say goodbye to your family... slowly”
Cons: its harder to service, heavier because you need a huge head tube, more to go wrong
Pros: literally nothing.
To be clear I was not defending it just truly curious why it always gets so much hate.
Back in the days the cable guides on bikes were for interrupted outer cables. There were more than a few aftermarket solutions to allow people to clamp their continuous outer cables (or brake hoses) to these existing guides. You could consider the fact that these guides through the headset are getting more common a good thing, if you really try hard. The more there are, the sooner there will be some aftermarket solution available for all those poor sods who succumbed to such a frame.
- so far those upper cups are not sealed, so more water/humidity can purge into the frame.
- requires more spacers under the stem.
- cables have more excessively smaller diameter bows. This may not affect performance with hydraulic cables, but can do with conventional steel-cables for shifter and dropper-posts.
- can cause more excessive cable-rub with the steerertube.
- not service-friendly at all. This, along with the cable-rub, is a deal-breaker for almost everyone.
This stuff is for sure not "consumer-driven", but just cost-effective for manufactors.
I would rather risk voiding warranty than have to warranty or replace a crappy headset every 6 months.
Please pass along the sentiment here. Headset cable routing means that I, and apparently hundreds of other people here will never consider purchasing this bike.
On a time trial, or actual race road bike, the potential aero benefits might be justified.
But they have no place on a mountain bike. Mechanics (home, or professional), do not want headset cable routing, because any time you work on the headset, replace a stem, mess with stem spacers, you will need to re-bleed your brakes, and re-adjust your deraileur.
No one wants this. Literally no one.
I think those bikes sell well, most people will think they need it, because.
I'm no XC Racer, but I've been eyeing an aluminum, "XC/DC" frame to replace my hardtail with for sometime (something like an alloy spur or alloy element frame only). Besides the internal routing, the bikes looks to fit the bill and I wouldn't mind replacing the headset and rigging up an external routing set-up.
Also commencal ect don't gain money by making it harder to service, just piss of consumers/mechanics.
Speaking for all mechanics everywhere, we don't want this, never have, never will, there is already enough work out there with people who either don't know how to do it them selves, or don't have the time. Good mechanics are snowed under, we don't want it wasting our time!
Let’s be honest. 3hrs on YouTube and some park tools and you can be a bike mechanic. I was one. It’s nothing special. 99% of it is unf*ckulating old shifter and replacing stuck posts. Building wheels. Servicing suspension. Bleeding brakes well. That’s such a small part and even that stuff isn’t hard after you do it once. Change my mind.
Wrenced in many shops and nobody wants headset cable routing. No mechanic likes working on these. Tri bikes, aero road bikes same thing; a pita to fix. The problem is that product managers at bike companies who design or sign off on these never have to fix em.
Complaining about revenue making things like this or shifting standards that makes people buy new is the most bike industry thing to do
I also want to know why Commencal makes a big deal about their stance on carbon, yet they spec their bikes with carbon wheels.
Just let me zip tie it to my frame myself, its not that hard.
It was just way too pricy for a teen based target audience.
I remember once crossing a street and I dropped a MiniDisc and then watched a car drive over it. I picked it up, dusted it off, put it in my player and it worked.
Haha. Well done.
If the weight isn’t too high this looks like a winner.
BTW, it is being reported that the bike weighs 27.5 pounds www.vojomag.com/prototype-commencal-bientot-de-retour-en-xc
That wouldn’t stop me from putting carbon wheels on it, though.
Its generally passable at best but this isn't a great example.
The physical effect from depth of field on a quality camera is still leagues better.
You could save a little more weight with the SC fork, a OneUp Dropper, and dumping the AXS, but this bike is never going to win the scale wars.
My opinion, XC is more closely related to Road cycling in its direction than Enduro, Trail or Downhill....or Down Country. The bikes are constantly being developed like road bikes; stiffer, lighter, faster, more aero. Integrated cable management came from road cycling from a purely aerodynamic standpoint.
Yes, for your average Trail or Enduro rider, the integration of cables into the headset is just silly and useless. But for those XC riders that desire the cleanest cockpit possible, its exactly what they want to see. No "ugly" cable bungs in the frames. Cables are hidden under or in the handlebars and simply disappear. And if there is an issue.....take it to the mechanic.
Luckily I have an old spreadsheet that can calcualte this. Just need to assume the frame weight.
This frame with shock and hardware is likley ~7lbs maybe a bit less.
Mathing out the rest using the spec sheet in the photo lands at 24.2lb, but add a pound for sealant, dropper post cable and lever etc.... and sub 26lb seems easily within reach. Commencal is known for heavy frames, but 7lb should be well within reach. Aggressive Al Enduro frames are 8-8.5lbs with a larger shock.
So
Holes in the steerer !?!?

/bike combo is photoshopped
Seriously, it's a sexy looking bike in a nice color.
before you ask - Im on the hunt for the perfect setup and if that means i have to ride every bike or component then i will.
Its great as it really shows the quality of parts and frames etc - it hugely varies between brands.
Having to bleed brakes just to change a stem or add a spacer is a no go for me.
The BMX/dirt jump crowd have tried all kinds of wacky variations on running cables into headset and around them. Given that a healthy headset is mission critical to landing big jumps, if funky cable routing were such a headset killer, they'd be the first to stop doing it.
Additionally, even with the holes in the HS cap, the dust and crud exposure of the HS is trivial compared to that of the hub bearings, and for us "average schmuck" level riders, those don't wear out every year.
Commencal's basically doing the same kinds of things Dangerholm does with cable routing, and when he does it, the PB boards light up with fawning praise.
Methinks most of the folks on this board just don't like the way the Commencal's routing looks, not that it's objectively all that bad.
If we want to know why headset routed cables do, in reality, nuke headsets after less than a single season, the answer is the cables. We've all seen water bead on our cables. Because of surface tension and other things, water flows down the outside of the cable housing, following cables, flowing with them like a freaking river. When your housing transfers right next to the bearing cartridge its literally delivering dirt & water straight to them.
And all this doesn't even begin to discuss abrasive cutting into soft, aluminum steerer tubes, maintenance, waste, bleeding brakes, etc.
Most of the time the headset, or stem are special parts that you can't even change.
For changing them you need to get off all the cables first. So instead of a simple 5 minute job it becomes " Let's bleed 2 times brakes and adjust the the dropper and drivetrain afterwards " Job.
The owner of the bike shop I work and the other mechanics hate this crap.
