Even if there is a very slight difference (which I doubt there is), you'd never notice it.
So in other words the difference is minuscule. I'm actually about to take some beginner track classes (CalvjanoTrackie?! Calvington?!) and since I'm in the market for a new bike I can commute with and take to the velodrome, I think either the 725 or 721 is a good choice.
I know!! haha Question is do I want slick welds? I kind of like the idea of the 721 though so I'm leaning closer to that.
ANyway, I looked at the geometry charts, and I usually fit a 53 better, around a 538 top tube length and a stem length anywhere between 90 to 110mm. I was wondering if I'd be okay with getting a 53 even with leaders long top tube? Worse case scenario is that I'd need a stem size 10 or 20mm smaller, which isn't that bad.
ALso, I forgot to add how stiff the Leaders were in general?
You may be better off with a 51. Because of the head tube angle and rake of the fork, you'd be better off using a shorter stem to prevent you from being too far out over the front wheel so keep that in mind when figuring out sizing.
My 725 is really stiff without being overly harsh and I know TT has said good things about how stiff his 721 is on the track.
Well, I think that sums it up, I'll be getting a 721. Though if you say it might be better to have a shorter stem, maybe I'll choose the 53. I was going to switch to a 100/110mm stem on my Kilo because the 90mm was so cramped when I was in the drops. If I get the 53 I may be able to just keep a 90mm on there.
I've got a 70mm on my 55. Just make sure you check all the numbers really well before ordering. A lot of people order the wrong size (ahem hamfoh).
Here's the 721/725/735 math:
Ha what an idiot! I heard he was looking at the 722 geo when he ordered too. Sigh, some people. Buy first, ask questions later, amirite?
I can ride with risers or track drops with a 70mm stem, fwiw, but bullhorns don't feel comfortable and I feel like the small stem makes the combo with the long TT feel weird to me. I'm sure I could eventually get used to it, if I can't sell it for the right price, but I do miss bullhorns.
calv, I'm normally a 58 and a 58 is definitely too long for me. I would measure yourself 500x before ordering a 725. I really want to run a 90mm stem or so, so I definitely wish I had sized down
I really like my 721. I have a 70mm on my 61.
I thought it was 'cause they are 25.4mm.
basically that combo is why I held off. silver + 25.4 - any other combination and those wouldn't have lasted a day I bet.
hopefully ordering a 722TS within the next two weeks..trying to figure out whether or not to get a 55cm or a 53cm. I'm around 5'10" with somewhere close to a 30-31" inseam. I currently have a 55cm Vitus 979 roadie that is goddamn comfortable and i was comparing the geometry to the 722 hoping i could get somewhere close. figured the 55cm might be my best bet. 979 has some tight geometry and i'm pretty sure the track 979 has identical geo.
Anyone have some insight?
getting more and more used to the 70mm stem (kinda forced to unless I want to move my crankset over to the soma in the meantime -- I don't) and may end up keeping the longer 725 as I just love the way it feels on a nice open road. I think today I'm going to put on the bullhorns and hope I don't feel like I'm doing yoga while doing. plsss feel good. plsss bro
yes, his concept is so unique.
that's what I was thinking
Retrogression needs to make an aluminum lo-pro frame and then sue Low who can sue Leader who can sue Cinelli who can sue Cannondale who will then go bankrupt.
