|I know that Heras and others used the triple to climb the Angliru
Do you know what gears he actually used?

|17:43 CEST 174 km/3 km to go
Casagrande is catching Mayo and the two have passed Gonzalez and are closing on Beloki, now the best part of a minute down on Heras, who (for the gear ratio obsessed) looks to be riding with a 30x23 or so bottom gear - I think that it will be a victory for the triple chainset today, although there is still a way to go...
I don't know what DA cassette he was using, probably still had a 25 or 26 to go.

|He used a 30x25 for some spots. I know that Paul, Bob, and Phil mentioned that Sevilla didn't go with a triple and instead went with a 39x29 setup. I've done climbs similar to this so I can appreciate the need to have this type of set up.

|Actually he didn't use a triple, he had a 53/30 big ring small ring and a 25 rear sproket. Beloki had a 53/39 with a 29 tooth rear!
|Is that possible? 53/30?||DougSloan|

|I'm not aware of any crankset like that, and even so, it would shift like crap, if at all. You sure it wasn't a triple?
|Is that possible? 53/30?- Yes||boneman|

|In 1999 when Jimemez won, Tonkov who came in second was using a 53/30 with a 26 in the back. Set up was DA. I don't know how they did it but the Eurosport TV feed and commentary talked about and showed the various setups. That year, being the first, a few teams/riders used triples as there was the fear of the unknown under race conditions. The following year, almost all riders were on doubles including Simoni, Ullrich and Heras.
Interesting to see the switch back this year.

|I guess you could use the DA triple crank, but run the 53 in the middle position; problem is, the DA triple crank does not have separate bolt holes for the 30 ring in the crank, but rather uses extension tabs on the inside of the 39 middle ring to bolt on the granny ring. Maybe they are not using a DA setup? This just doesn't make sense, if they are using DA, plus, I just cannot possibly imagine they could get the front to shift directly from a 30 to a 53; you'd be slamming the chain right into the side of the 53, rather than having it close enough to cleanly pick up the chain. I need to see this.

|A 53/30 double is impossible with existing equipment. The smallest inner ring a shimano double road crank will accept is 38t (bolt ring is 130mm). On a Campy double road crank 39t is the smallest (135mm bolt circle). Even if Heras's tried to use a standard (110mm bolt circle) mountain bike crank he could not fit a 30tooth ring in the second (middle) position. If he used a micro drive mountain bike crank (94mm bolt circle) he could fit a 30tooth in the middle position but then good luck finding a 94mm bolt circle outer ring with 53 teeth (they don't exist)(not to mention the bottom bracket spacing issues that would be created by attempting to use a mountain bike crank). Finally, no front derailler ever made (double, triple etc.)can handle a 23 tooth jump between adjacent chainrings.
I watched the stage on OLN and per Phil Liggett and what I could see Heras and all the Posties were running Dura Ace triples. Per Phil they were running 53-39-30 with a standard 12-25 cassette.

|The standard Dura-Ace triple is 53x39x30, and it sure looked on a triple on television, to the extent one could tell through the rain and fog. I would assume that a team as savvy as U.S. Postal would use something standard and proven on a ride that important.|| |
