|   Action-tec or Cycle Dynamics cassette? | B R H
Oct 29, 2002 12:50 PM | | I'm going to try one of these lighter cassettes but I'm having trouble deciding which one. It sounds like the GoldTec just won't cut it, so I'm looking at the all Ti versions from Action-tec and Cycle Dynamics. Cycle Dynamics has been very responsive to e-mails. Their website makes a big deal about "gear cut" teeth. Is this a big deal? Also, it appears as though the Cycle Dynamics cassette is not heat-treated nor is there any other mention of hardening. Action-tec offers heat-treated versions of their Ti cassettes. Anybody have experience with either of these? |

Oct 29, 2002 12:55 PM | | but not the heat treated version. It's probably overkill.
I can't decide if I want to stick with 8spd or go back to 9. |

Oct 29, 2002 1:09 PM | | You reported on the GoldTec cassette right? I think I'll just wait for you to post results on the Action-tec too! :)
I'm guessing you're considering going from 8 to 9 for reasons other than dirt problems? Aren't you one of the guys running only 2 chainrings up front? Are you worried about obsolescence or do you need the additional gears with for a 2x9 or ?
I'm hoping 8 speed will allow me to have fewer troubles in dirty conditions on longer rides. Is this wishful thinking? |

Oct 29, 2002 2:02 PM | | The Ti cogset should hold up a long time. My original reason for the 8 speed was weight-driven., and still is. I never had shifting issues with the 9r. And, no, I have a 9sp triple up front, 44/32/22. |
| Cassette weights. | B R H
Oct 29, 2002 2:58 PM | | Weight is important to me as well (another reason I am considering 8 speed... I also was happy with the steps between gears that my old 7 speed offered though so I haven't ruled that out yet either!). The Cycle Dynamics 12/28 is shown as being 140 grams. I'm not sure this is correct though since their 12/26 offerings are shown as weighing slightly more. All their 8 speed cassettes are on sale right now for $139 (US).
Do you have any weight info on the Action-tec offerings? I don't believe I saw any on their website. |
| I called Russell and went over the weights with him | pedalAZ
Oct 29, 2002 6:01 PM | | If memory serves, the 8spd 11-30 was around 215-220 grams and the 9spd 11-32 was around 235. |

Oct 29, 2002 10:04 PM | | I don't have any weights, but I have been using 8 speed Action Tec Ti cassettes on my cyclocross bike for 4 seasons now. Granted I don't ride the bike all that much except during CX season, but the cogs have held up extremely well in the less than ideal conditions found in CX racing (mud, sand, snow, etc.) |
| consider this one too: Inferno 11-32 149g... | nino
Oct 29, 2002 11:25 PM | | as posted about 2 weeks ago i still have that 11-32 Inferno one piece cnc`d Aluminium cassette.it`s kind of hard anodized.149g (154g incl. lockring).it has shifting ramps and shifts good but won`t last too long if used in mud.I have a 13-26 road cassette of the same brand and after well over 1000 miles it`s still in great condition.just the 2 most used middle cogs start to make a slight rattling but nothing to
bother.shifting on my cassette is equal to Dura-Ace cassettes.
it`s new and has never been mounted.it sells for 135$ at Inferno.I would sell it for 85$ + shipping

| What about Cycle Dynamics titanium cassettes? | tankhead10
Oct 30, 2002 6:16 AM | | Has anyone used these cassettes? They give some interesting information about the reason to use 6/4 titanium for a cassette and for chainrings. Are these bits of information valid or hype? It sounded good. The link is on the next 50 under a similar topic about gold tec cassettes. I emailed them and am waiting for a reponse. |
| What about Cycle Dynamics titanium cassettes? | Too many bikes to ride!
Oct 30, 2002 6:40 PM | | The reason they or any bike company uses 6/4 for certain applications is because of how hard it is. Unfortunately it is tough to work with, except in things like dropouts and cassettes.
When it is used in a tubing format, it becomes very difficult to work with. Even tougher is 7/11 titanium. Only one company has used that mix of ti, and I am not sure if they even use it anymore.
When a tough material is used, it is alot easier to use when it is machined, like on a cassette or dropout.
Hope that helps.
