2 Cracked stems? Deda and ITM

[xcnick]

I'd like some opinions on this if possible! The first photo below is of the inside of a Deda Zero100 stem the i stripped to inspect due to occasional creaking. I don't think there's any doubt this is cracked! I bought it second hand in January, that's a lesson learned!



This next photo is of an ITM super over stem that's had maybe 18 months of use that I have just dug out of the spares to replace the Deda for now. This also has a similar line also on the lower part of the stem-both have been run negative rise. I'm not sure if this is a crack or not? But concerned due to the Deda above.



Has anyone had similar experiences with these stems? I like the Zero100 and tempted to just order another but I'm extremely concerned now!!

Damn. I would not trust riding them.

I'd suggest, just for security of mind, going up to a stronger stem. Maybe like the Pro Vibe Mark Cavendish stem or even the Theo Bos stem.

Buy a Cannondale SystemSix ControlTech stem. You'll never break that.

Thing is is I'm a weedy 65kg and 5ft7 on a good day! The Deda was paired with a Zero 100 bar and I went for this setup due to a good reputation. I'd really like to keep my cockpit all the same if possible, and I like the 82degree angle. Have I just been unlucky? Both stems are 110mm

If you're in North America, try contacting Deda warranty and see what they have to say. I found the service from them to be superb.

Unfortunately I'm in the UK. I have just found the distributor details for Deda here so will see how that goes. No receipt though...
