TCU vs Flex Cam

Can somebody tell me what advantage a TCU has over a Flex Cam or vice versa? I know the difference in the two units but have no idea how one might be better than the other or is it just a preference thing? I will eventually get into trad (after I take guided courses) but for now I am just curious.

besides the obvious of 4cu vs 3cu, i think that i would feel more comfortable placing a flex cam in a horizontal placement because of the floppy stem.

Flex Cam - Single Cable design has more movement before the cam begins to move in the crack. Four Cams offer more stability and better holding power.

TCU- Three Cams are faster to place and can be fit into more places.

Faster to place? How so? And with Aliens, I'm hesitant to say that a 3CU will fit in places Aliens won't, C3's notwithstanding. Those babies fit in impossible placements.

The OP didn't mention aliens nor BD's, but the compison between a Metolius 3cam and a Trango 4cam.

To answer your question though:
The 3 cam units are faster to place as the process of looking at the crack is easier and imperfections to set that center cam in are easier to spot. In addition, when the crack is shallow, the 3cam can generally just be placed, where a 4cam often has to be set with the cams specifically alligned. Also, in pin scars or flares, it takes more time and effort to set a equivalent 4cam unit.

(Admittedly, I agree with you on the aliens, but am hesitant to open that can of worms on here, and it was beyond the scope of the OP's question)

That is one thing I was thinking about. I've seen pictures of the Metolius cams placed in horizontal positions and it looks really stressed. Thanks for the replies. I will be sure to ask plenty of more questions to whomever I end up getting as a guide. It will most likely be Texas Mountaineers.

Stressed, describes it fairly accurately. I love my Metolius cams, love the way the place, and hold, but.. I have a few that were weighted pretty heavily while in horizontal placements, the cable ended up rather deformed. Even after straightening them, they are just never the same, the smooth action is gone I've been really impressed with the BD C3's for both vertical and horizontal placements. Personally I think you need a mix of cams. My big cams are a mix of BD Camalots and Trangos Max Cams (which btw, there is a recall] on the #1)

I don't know why you'd compare these two specifically. Similar price? I can't tell you the difference other than I know I prefer single-stem cams. The one time I racked up with some friends Flex Cams, I thought they were excellent cams. You don't hear about them much, considering their more-hyped rivals though. You need to play with different types of cams because, like you say, I believe it all comes down to preference more than anything else. You need to figure out what you feel comfortable climbing above.

Aliens up to red, then C4's. Anything else is second rate.

By the way, did anyone notice that CCH now has a website?

funny how they don't mention anything about the latest questions of their quality control surrounding their product.

January 12, 2006
Colorado Custom Hardware (CCH) has recently completed an investigation, and extensive testing of our product to identify and isolate safety issues concerning the brazing on CCH Alien cams.The safety of our customers is our number one priority and therefore we are issuing a recall for any cam bearing the marking described below.

The units with this issue are marked with a small center punch dimple (picture) at the base of the round ball where the axle goes through the cable eye. Although few failures have been reported, CCH recommends immediately discontinuing the use of any Alien cams with this mark. We are issuing a full recall of these cams. Please return them to CCH for a free replacement. You can mail your cams to:

Colorado Custom Hardware Inc.
ATTN: Brazing Recall
115 East Lyon Street
Laramie, WY 82072

CCH has always worked to assure the absolute highest quality of every cam we produce, and we are currently working on ways to further enhance our already stringent standards of quality control. Again, I would like to reiterate that ensuring the quality and safety of all CCH products is our highest priority.

Sincerely,
David Waggoner
President of Colorado Custom Hardware

looks like they're coming up a little shy in that department since then..

Thanks dude. I actually post on erockonline now and then under this same name. I only have a couple friends that trad and they are n00bs at trad so they aren't the best to learn from but not ignorant either. Thanks for the offer to meet up at erock too. I might take you up on that sometime soon.

Actually, In the info provided with the products, a single stem cam (bd .75&2 C4) has no strength-wise advantage over a double stem cam (Metolius 00 TCU). They information says that they BOTH loose about 2KN of holding power when loaded in a horizontal crack with the stem over the edge. This is independent of other advantages or disadvantages.

That being settled, I would probably choose a TCU for smaller pieces and a Flexcam for larger pieces, but I'm not very familiar with Flexcams. I trust they're similar to BD C4's

If you actually read my post.. you'd see that I never mentioned anything about a "strength" or "holding power" difference, but was in fact referring to the way in which Metolius cables tend to "ended up rather deformed"
when "weighted pretty heavily while in horizontal placements.", and the subsequent effect on the cams action.

You also might want to read your own post..

Yes, they are similar.. in that they are both cams.

BTW. It's not necessary to underline your entire post when you *think* you have a point to make.

Abraham,

these are some bad pictures... but they are examples of what skinner was talking about.


this damage was from when the cam was used as a directional for a toprope.

i appreciate your info about the loss of holding power on either brand, however it seems that the bd's are WAY more resilient -- at least in resisting this kind of damage.
**edited to remove bad pictures**

oh btw, Skinner, lighten up a bit, the kid is only 16 and trying to contribute.

If YOU actually READ my post, you'll find out I never said anything about you being wrong. I'm pretty familiar with metolius TCU's and I know exactly what you're talking about. Same thing happens to every single wired piece I've ever seen. (think stoppers and hexes, not just cams). I just wanted to clear that out so other people out there wouldn't get confused thinking there was a difference in strength.

guess what... shielded cables also get deformed. Really. If the manufacturer says the holding strength is 2kn weaker, I think we should believe them. (Of course, if you have actually tested a significant number of TCU's vs. Flexcams and found that TCU's are weaker, I apologize)

You got imaginary killfiled. I hope you're not offended. I was going around imaginary killfiling people after a few Beers last night. I even killfiled Dingus, which is something I'll probably come to regret. The trad bug thing is directed at somebody else? I already have it amongst others....peathe out...
