Suggestions for TT stem?(8 posts)

Suggestions for TT stem?Drupa
Dec 4, 2002 7:06 PM
Want to avoid the hyperlight variety - I have seen too many break. I am running a cowhorn bar with airstike 2000. Looking for a stiff and stable 110 - 120mm. I had been leaning toward the Thomson, but it seems like it may be a little too heavy at 200g. I would prefer a 4 bolt, but would like any advice on reliable stuff you guys have ridden.

I am 175lbs...

Thanks

If you are just looking for stiff a reliable stem, the Ritchey WCS is probably your best bet and not too spendy. It has 4 faceplate bolts and bolts in opposition on the steerer clamp.

You've seen a stem break?? That has to be interesting.. I've seen recalls because of poor bolts and there were issues with the face plate on the early deda newtons breaking, but that is it. Stems are borderline on impossible to break. Flex yes, some light stems will do that. I ride a 3TTT Zepp, which falls into the superlight category along with the ITM Stem, the Newton and a few others but it is wonderful. The only possible issue is that the Ti hardware needs careful attention when using the hex wrench or you might strip the interface of the bolt.

Just last weekend, a bike courier came into my LBS with a broken ITM and a bashed face. Wasn't a crash, appeared to be a fatigue fracture. Broke at the steerer weld. The month before, we had a 3T with the same problem - fortunately that guy wasn't hurt as bad.

The steerer weld?? I can picture broken face plate. I guess.. I can picture a stripped bolt, but the steerer weld? Maybe I'm not sure where you are referring to. Most light threadless stems aren't welded but machined out of a solid block of aluminum. Breaking the stem itself (catastrophic snapping) would take some impressive force on my 3T-Zepp. I honestly wonder if stems are breaking at the steerer if installation is an issue. Oh well.. I'm not arguing here.. just having a hard time picturing it.. obviously the stem takes a lot of torque.. A broken stem still sounds baffling to me.

This is not something you mentioned, but when I put a Look Ergo stem on my Cervelo, my comfort and speed improved. I can lower and extend it for a fast 10 mile TT, or raise it for 100 miles (or whatever). It really does help to dial in position, as you can freely experiment with some pretty radical positions. The weight penalty is neglible compared to the benefits of good position, vitally important in time trials.

For a fixed stem, I'd stick with an ITM Millenium or Ritchey.

Thanks for the advice.

I try not to buy anything made in France - just makes me nervous. Nothing French has ever instilled any confidence in me!

You don't even trust Mavic wheels? You just described a catastrophic failure of an Italian part (ITM) -- does that disqualify all Italian parts? If you base your buying decisions primarily on nationality, I don't think I, nor maybe anyone, can help you much.

Wow, didn't think about the wheels - that sucks!

I repair many brands of espresso machines for several chains. French machines are very hard to work on and always inexplicably use non standard parts. The new automatic machines that Starbucks is placing in all its new stores were having some serious troubles last year because the french components were failing. They had to be retrofitted and replaced with newly designed parts (non-french). I have found that I am better off having a french prejudice.

Don't forget the anti-American french culture, the endless news stories describing their labor force's laziness and culture of entitlement and, of course, the Renault.

I hate, and avoid, all things French.

Other than this one prejudice, I am open minded and embrace diversity.

I am going to have to eBay my cosmos wheelset - Luckily, I got them at deep discount.
