|   2003 Ti Eggs | Mycroft
Oct 27, 2002 12:35 AM | | Just got my triple Ti Eggs and thought that I would post some info for you guys.
The triple Ti is eye candy!! Gold Ti Nitride treatment for the spindle, and spring. The rest is Ti grey except for the endplug, which is now gold anodized Al.
I am impressed that Crank Bros has used the harder to work and far more expensive 6Al/4V Ti, instead of the cheaper and softer 3Al/2.5V Ti in all its Ti parts. The nitriding is a nice touch to keep an extra hard surface treatment.
Now for the weights for the 5 models:
- Triple Ti claimed 185g per pair (actual weight 184g for mine)
- Twin Ti - 218g/pr
- Ti Egg - 230g/pr
- Stainless Steel - 266g/pr (~20g less than my 2002 SS which was 286g).
- Egg Beater Chrome - 294g/pr
The construction differences are:
- Triple Ti (list $400) - Ti in Spindle, Body & Wing; SS (300 series) spring. The gold Ti spindle is quite a lot more substantially built (thicker) than the SS one.
- Twin Ti (list $300) - Ti in Body, Wing, SS (forged 420) Spindle and Spring (300 series)
- Ti Eggs (list $250) - Ti in Body; SS Spindle, Spring & Wing (17-4 ph SS)
- SS (list $140) - SS in all, Body is 17-4 ph SS.
- Chrome Eggs (list $100) - looks quite a lot different
Weight savings over SS equivalent:
- Ti Body: 36g/pr
- Ti Wing: 12g/pr
- Ti Spindle: 33g/pr
At the shop, I can tell you that hefting the Triple and Twin Ti in hand, there is a clear difference in weight (even at 16.5 g/peddle).
Vs the SS Eggs:
- the triple Ti is $3.21/g saved
- Twin Ti is $3.33/g saved
- Ti Eggs is $3.06/g saved
Hence the best value ranking by incremental dollars/g saved is the Ti, Triple Ti and finally, the Twin Ti. Although, at $400, the Triple Ti is described as fiscally reckless!!
Just installed it today from its beutifully-designed immaculate 6061-16 gold anodised extrusion case onto my Ellsworth Truth. Riding the bike, immediately felt so much lighter from my prev SS Eggs. I flew over the track today, climbing skywards.
But then I discovered that this surge of performance from the 102g savings may have been entirely the effect of my wallet - which is now so much lighter.
Excuse me while I go see my psychiatrist about a small problem that I have ... I believe that its called Weight Weenies' Psychosis.
I think that a number of you may have it to ... |

| Nice job with the information but........................... | tankhead10
Oct 27, 2002 11:50 AM | | are there any rider weight limits for the different ti beaters that are posted in the descriptions of the pedals. Like "No one over 165 lbs. may think of using these pedals." tanks again for the great info! |
| yes, great info, but..... | VT Mike
Oct 27, 2002 12:42 PM | | i'm curious about how durable the pedals with Ti wings are. I know there have been some pretty long discussions here about which is harder - Ti or steel. I've smashed the wings of my eggs on some rocks pretty hard and they have held up well. I wonder how the Ti wings will compare. |
| 6Al/4V Ti ... | Mycroft
Oct 27, 2002 1:39 PM | | Is generally accepted as the toughest and strongest Ti alloy available. The other 2 are Commercially Pure (CP) and 3Al/2.5V Ti (found in most Ti bikes).
Ti is more ductile and has a stronger tensile strength than Stainless steel and has a higher point of fracture, as I understand it (not being a materials engineer).
So, I am not overly concerned about it holding up vs SS. Most of the better Ti bikes have their rear deraileur hangers made from 6Al/4V Ti for the reason above.
However, if I have a problem, I'll post. |
| Weight Limits ... | Mycroft
Oct 27, 2002 1:31 PM | | The LBS guy said that he was informed the weight limit for the Triple Ti was 200lbs. Don't know about the rest of the eggs - whether this applies or not.
This last bit is not mentioned in the catalog that I have from which most of this info is derived.
Guess this might rule a number of folks out if correct ... |
| @ Interbike, Crank bros said......... | Fulton
Oct 27, 2002 3:31 PM | | there is no rider weight limit, they will warranty anything that breaks, but they reccomend keeping it under 185 on the ti spindle. The cromo (ss?) spindle is quote "Clydsdale Approved" |
