Everybody's gotta learn sometime
That looks pretty normal to me, the top one anyway (leg extension). Ride it for a few hundred miles and get used to stopping and starting?

FWIW on my small road bike with 700x40 tires and 70mm bb drop and road shoes I can stop at traffic lights, seated, with one foot down on the very tip of the shoe just to balance. I can imagine with slightly different geometry and shoes you might have to lean the bike to do that, or just hop off the front of the saddle - both are fine and normal. Just get used to what you need to do for your bike.

Both look good in terms of fit. The bike miiiight be a little small but nothing that fit was and flexibility can't fix. As others have mentioned , when at a red light your butt should be off the. Ike and over your top tube. That's the safest way to be at a red light without falling over.

Also arch/straighten your back a bit. It shouldn't be curved like that while riding. You can do this be sticking your butt out a little. That will also get your soft spot and sit bones onto your seat. Bend your elbows a bit as well.

I'm no expert but it seems mostly ok to me. I would tip the handlebars up a bit so you don't have to change your position that much to make good use of the hoods.

Hoods are for aero though and you'd want to be able to shift your position at the hoods. Looks good to me. It's really the back arch that's bothering me right now. Otherwise it looks good. If you are finding keeping your back being difficult the it's a strength thing. Do some planks in addition to cycling to strengthen your core.

This is a picture of my first bicycle fit. Notice the change in position. I’m also pedaling smoother (I can link the video if you want) but notice how the back angle changes. Ideally, you want to look similar to that; they achieved this for me by lengthening the stem and maintaining a flat hood and handlebar.

The left is the fitted bike. The right is the before.



I personally wouldn’t move up the seat to try to achieve this. If anything, your seat at 30.4” looks fine and in fact looks better. Bend your arms some more and make sure you’re looking up (and not down at the tire).

Edit: Can’t believe that I really got into cycling with that fit 8 years ago. Been a long road.

Without seeing more than one frame and also a posterior shot, we can't draw anything definitive from the posted photo. Even sitting on a saddle slightly crooked or canted will have a major effect on knee angles. This is why I'd rather just get a reliable measurement of his book inseam, use the Lemond method and subtract 1-1.5cm from it.

As someone who recently had to learn how to unclip and stand over the top tube at lights in metropolitan traffic after a bike fitting, it's really not that bad once you get a feel for it!

Sometimes you nail those push offs when the light turns green and you clip immediately in without having to "search" for the pedal and it feels rad even :)

A video would be better. preferably on a trainer pedalling at your normal cadence and against a reasonable resistance.

I moved to an area with some serious climbs and I am really bad at climbing mountains.
My casette is a 11-28 and I have a ultegra 6800 short cage rear derailleur. Shimano says 28 is the largest possible casette but I want a 32.
Some people wrote on the internet that on their bike the short cage work with a 32 casette.

What are my options ?
If I try it with the current derailleur and it doesn't work, do I need another (longer) chain once I buy a long cage ?
Derailleurs are hard to find these days, can I use a shimano 105 R700 or ultegra R8000 with my older 11 speed ultegra 6800 shifters ?

If you get an 11-32 you'd need to get a longer chain anyway.
You can use R7000 or R8000 fine with your 6800 shifters.
Another option is to get different chainrings - if you're on 53-39, say, going to 50-34 would be a massive difference.

I'm not sure what your best option is, but there's a good website for figuring out which Shimano bits are compatible with eachother:

Get a Wolf Tooth Road Link. I have a 6800 medium cage RD which supposedly maxes at 32t and with the Road Link I was able to use a 42t cassette. You shouldn't have to worry about blowing apart the RD with a 4t jump.

The Road Link just drops the RD down from the hangar and is relatively cheap and easy to set up with some B-screw adjustment.

Like Vando said, the RD you have can probably fit a bit larger cassette than officially stated so perhaps try the cassette alone first and see it it works. Shimano understates the max capacity for their road stuff as far as I know.

Also as Vando said, make sure your chain is long enough before anything else.

I’ve got to buy a new casette so will also get a new chain. I hope that if I got the new chain and it turns out not working without the hanger extension I can then fit the extension without needing another new longer chain.

I went to an empty parking lot and tried out the 30.4" seat height, just using regular shoes for now. Starting up was actually pretty easy, but getting off the bike in the proper way was a lot trickier.

They’re good but slightly sell-y, at least in the past, meaning, if you’re coming in with a saddle you like, or shoes you like or what not, they would try to sell you on the saddle or shoe they preferred. For a friend of mine, they were really pushing for the saddle they had developed at the time. They also really hate leather saddles (even if that’s your preferred saddle for your use-case).

They never pushed me on anything but the saddle, and it’s actually a really nice saddle.

Anyway I doubt they’ll push the saddle super hard on current customers because they don’t have any to sell.
