Ceetec Launches $390 Phenum Alloy XC Race Stem that Weighs 100 Grams

Swiss Components manufacturer Ceetec has launched a new lightweight XC race stem with a claimed weight as low as 100 grams.

Ceetec's Phenum C10 stem was designed for racers looking for a light but strong stem for their race machines and uses the Swiss brand's proprietary 'Full C10 Metal Matrix Technology'. The brand CNC-machine the aluminum and then use quenching and tempering post-processing to achieve a higher strength from the alloy. The metal then goes through a three-step process of surfacing and anodizing to achieve a matte finish similar to carbon.

The Phenum C10 is available in four different lengths of 70, 80, 90 and 100mm, with all sizes featuring a -18 degree rise. Ceetec claims that the stem will weigh 100 grams for the 70mm offering. The overall weight rises to just 121 grams for the longest 100mm length.

Ceetec offers a choice between black or gold titanium bolts.

Ceetec's Phenum C10 is not a cheap option for those looking to drop some weight on their XC bikes, as it currently sells for $390 // €318. You can find out more about Ceetec's lightweight stem here.

 Phenum sounds like a body part that would enjoy being licked.

 Don't dude that, Mr. Boxmtb! You know it' A L U M I N I U M, and we all know that will explode on your first descend.... not like Carbon! Also, recent studies, indicated that Aluminium, can diminished your P E N I S size.... contrary to Carbon!

 @adrennan: Stems do not have to be e-bike rated. That would be like an e-bike rated seat or pedals.

 nice. were the bolts 4.20 grams each?

 Or you could buy a hyperstem that's about half the weight, half the cost, available 40-120mm and rated for enduro use.

 I'll think I'll stick to $25 generic or no-name stems and keep $365 in my pocket.

 Or you can support Canadian instead since you appear to be from Canada? I spent $140 CAD on a stem from 9point8 because it was made here. Not based on price or anything else. And the quality is beyond that of what I've seen from Raceface or some others. Highly recommended.

 @noone1223: I have never heard of them but have supported your countries bike industry since Balfa started. I will certainly check these stems out. Thanks!!

 I bought one of those cheap Brand-X "enduro" stems from CRC and its appearance doesn't inspire confidence. Fortunately it wasn't destined for a MTB, and I'm not sure I'd want to pinch pennies on a MTB stem.
  • 1 0
 @noone1223: I have no problems supporting Canadian companies. I've owned bikes with frames built in Canada - Marinoni, Miele and Norco (Yes. Norco used to build frames in Canada) and I currently own a bike from a Canadian company (Argon1Cool but the frame is from Taiwan. I run components from Canadian brands including RaceFace and SquidWorx. I've used DeKerf to restore and repaint an old steel frameset and I try to shop locally. My next bike could well be a Devinci Kobain because the frame is made in Quebec.

But I'm not made of money and the thought of spending anywhere close to $100+ on a threadless stem is mindboggling. Stems are machined out of aluminum and to me are functional items, rather than aesthetical. 7075 aluminum has the same metal and chemical composition, no matter their origin - the same goes for 6061 aluminum. In my decades of cycling, I've never had a stem - no matter the cost - fail on me.

 79g for the same length at a fraction of the price. And it also looks better.

 I was going to ask how you get that on your bars without a removable faceplate until I remembered I'm on PinkBike and not RoadBikeReview. Still would be annoying to have to take the crap off your bars to remove them from the stem, though.

 Wren stem 80 grams for $80.00

 Usually $45 on Nashbar. I’ve had one on my SB100 for a full season, and it’s great. Not quite as stiff as other stems, but that’s not a big concern for me. I also run Wren on my CX and one of my road bikes... zero issues, and amazing weight to dollars ratio.

 I still just don't understand the allure of a super light stem. I get it. . . . This is aimed at the xc race/weight weenie group (I would imagine this would be more at home on a road bike or hill climb bike). However, for me, the allure of not knocking all my teeth out and breaking my neck is much greater. I'll stick to burly stems and forfeit the 50 gram savings.

 1. They need to make a 60mm. Maybe even 50mm. With the way XC bike geometry is headed even 70mm is too long for some of folks.

2. The difference between this and a Race Face Turbine of the same length is 21g. That's 0.05 lbs. That's 5 100th's of a pound. The RF Turbine retails for about $100.00 US. You can find them for $85 no problem.

I don't mind paying a premium price for premium parts but this goes too far. $150.00 max.
