1.) What year was OCLV120 introduced, '01? Or was the 120 always what they produced, but decided to call it 120 when they introduced SuperLight, 110?
2.) What OCLV did Lance use in the '99 TdF? TREK claims that the 120 is 100grams lighter than the '99 Tdf winner.
3.) If & when do you think Trek will switch to an integrated headset and a full carbon fork?


Some answers,TJeanloz

1) The OCLV120 was introduced after the Tour (August) in 2000, as a 2001 bike. The previous OCLV would have been a '150' in the same nomenclature.

2) Armstrong previously rode an OCLV '150', though Kevin Livingston tested the OCLV120 in the 1999 Tour.

3) I doubt we'll see an integrated headset; though what they have on the 110 is integrated for most intents and purposes (it's a proprietary size). I'd guess we'll see a full carbon fork within two years. I'm really not sure why they don't already offer the option.

As you may know, the '03 5200 & 5500 now have the OCLV110 straight blade fork(trickled down from the 5900). Do you expect the complete 110 frame will trickle down eventually? I'd imagine more than likely, but in how many years?

on how much lighter Trek figures the material can stand it, as they'll have to come up with a lighter version of the 5900 (OCLV 100?); also, the ride is completely different and the 52/5500 has a lot of fans.

Oh, yeah, the OCLV110 forks are not exactly the same, though what the difference between them accomplishes, outside of minimal aerodynamic improvements for the 5900, is beyond me.
True about that OCLV110 fork. It probably isn't much lighter.nmjtferraro

just a clarifier~
the oclv110 straight blade fork on the new 5200 & 5500 is nowhere near the fork of the 5900. The legs are different, but more importantly, the 5900 fork has a carbon crown vs. the alloy on the 52/5500 fork. it's more a style change than a trickling down of technology.

the 5900 fork, with alloy steer tube, weighs in just over 350 grams vs ~ 550 grams for the 52/5500 fork. the huge difference comes from differences in the crown material. ke

keep in mind, the weight diff in the forks is one of the big reasons the 5900 frameset is so lusted after. most of the weight savings come not from the tubeset (110 vs 120) but from the fork & headset.

personally, i don't see any reason for trek to come out with a complete carbon fork - too many failures associated with improper installation & zero weight savings. the 5900 fork is one of the best on the market, imho.

it won't shock me at all to see an oclv99 tubeset or something like it in the future. the technology already exists, albeit in an expensive form. that, and a bit of planned obselescence have kept it from hitting the market.


ps. to win the official "trek-weenie" award, tell me this: is it possible to install said 5900 fork and headset on a standard frame? the bottom cup/race is oversized, but if i remember correctly, the outer diameter of a 5900 frame appears to be identical to a 5500 frame (1&1/8 headset). could one press a 5900 headset bottom into a 1&1/8 frame?

the answer is no. From what I remember (note to self: study up on Trek trivia), the bottom cup on the headtube of the 5900 is oversized, which means said cup won't fit into a smaller hole (to make the visual easier). A bit like the square peg-round hole deal, but round/round. Oh, forget it.

No, it won't work.
That was my gut reaction,TJeanloz

My initial answer was what you say, but the implication of that is that you could use ONLY the supplied headset and fork with the 5900 frame, which is possibly the case, but I'm not sure of it. It's pretty rare for a manufacturer (other than Cannondale) to require a proprietary part like that, because it's a big turn-off for high-end consumers to be stuck without choices.

I understand that the fork and headset are an odd size and NEED to be used together (i.e. you can't swap out just the headset or just the fork); but I'm not so sure that the cup itself is a different size- meaning that they aren't replaceable with anything else.
I didn't realize the leg were different. Also, r u sure about..jtferraro

the weight of the 5200/5500 fork? I have a '01 Trek catalog in front of me and the specs for forks are as follows:

5900 = ICON OCLV SuperLight Carbon Air Rail OD. Oversized 1-1/8", .77lbs., 348g

5200/5500 = ICON OCLV Carbon Air Rail OD. Oversized 1-1/8", .99lbs., 450g
