Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Impressions on size of new bike

Just received my new Planet X RT-58 v2 Alloy Shimano Tiagra Road Bike.

I'm hoping to get some first impression feedback on the size of the bike.

Is it possible based just on the attached images to say if this frame and setup appear to be too small for me?

FYI I am 182.5cm with an inseam of 86cm.

The advice I received on this forum and from customer support was to purchase an L, as the bikes appear to be sized up a little.

If you need more images to provide better feedback please tell me.

Not bad. I'd probably slam that stem, and maybe go for a longer one. Seems like the reach might be a bit short but depends on preference I guess. I'd want a little more aggressive fit.

When my hands are on the drops, I can see the wheel hub in front. As a general rule the handlebar should cover the hub when on the drops. So you might be right.

Would "slammng" the stem in this case mean simply flipping it over?

Well possibly flipping it but moreso getting rid of the spacers. But again, it's preference. It looks like you have a pretty good endurance fit there. If that's what you are going for then you might be right on the money.

Yes I should have clarified, I am looking for an endurance fit.

Not to be a downer, but since you ask for unvarnished opinions I think it looks small for a classic endurance fit. On the other hand, "endurance fit" is not that well-defined and your bike and position both look great to me.

Looks like it's in the right ballpark - with stem/spacer adjustments you should be fine. At this point, I'd put some miles on it and see what needs tweaking.

On the hood's you're at a pretty standard 45 degree back / arm angle. I'd say the size is bang on, and it's a good position to start with. Don't listen to the peanut gallery telling you to slam the stem, at least until you've built up your fitness and figured out what type of fine tuning you'd like from your bike.

Looks a little small to me...but (full disclosure) I think almost everybody rides bikes that are too small, with the bars too low. I'm an old, stiff guy who's been riding for almost 50 years, and nothing has made as much difference in my comfort and performance as abandoning the idea that the pros' riding position was ideal for everybody.

Can you bend your elbows? Wondering about the amount of elbow/knee overlap. The cockpit may be a bit cramped, but the longer stem can probably wait as you adapt to the roadie aero position. If you get a lot of miles in, those spacers below the stem will likely come out. With the right saddle, you can roll hips for a flatter back.


Here's a decent position for 'just riding along smartly'.
edit: for reference, i'm about 2cm taller and slightly longer inseam.

What you're showing looks OK. However, I wonder about positions you don't show; you're showing straight arms in all three. I think the best fit allows comfort in a greater range. For instance, you may not be in the habit of riding in an aero position, but can you get comfortable with a loose "handshake" grip on the hoods and your forearms horizontal? When you get up on the pedals and lean forward, do your elbow bend much, or do they stay fairly straight? Are the transitions between aero, normal, on the rivet and standing smooth and natural, or do you find yourself adjusting awkwardly in any way?

Frame size looks right, next size up would be huge for your size with a 590 top tube length. I'd experiment w/ lowering stem first, don't cost nothing, then take it from there. Then look at whether you'd want to lengthen it a bit.

Looks small to me. But then I favor a stretched out position. For sure lengthen the stem and bend your arms.

Do your hips rock when you pedal? If so, the seat is too high. and IMO it looks like it might be a tad high. Otherwise, you look good, except for your elbows.

If you ride on roads without bending your elbows, you probably transmit lots of pain to your hands, wrists, elbows, shoulders and upper back ... not a recipe for comfort. You may not sense it as pain, but that's what it is.

Looks about right to me too. Agree try to bend elbows a bit.

That said, true fit depends more on feel than looks.

Seems ok to me. As you get stronger/lower on the bike, you might want to get a 10mm longer stem with a lower angle.

Looks fine to me. There are adjustments you can make BUT DO NOT MAKE THEM NOW.

Ride this bike in this relatively neutral set up and slowly you'll know which adjustments to make as time progresses.

It's a slow process but as you ride your body will give you feedback on what position it'll rather be in etc. It can take months at least to completely have you bike set up in it's final form. It took me nearly a year and a half to get my configuration in a way that felt "just right".

Congratulations on the new purchase!

Close. Now go ride it and report back. But put enough miles in to make it a meaningful assessment.

Thanks for all the great feedback.

General consensus is the frame is not too small, so I'll keep the bike.

Took it out last night and it felt good. As good as a road bike can feel after 18 months without one, and riding a town bike every day.

I'll take some pics of me on the bike in a lower position tomorrow when my new pedals and shoes arrive.

I would say that it's about right, but possibly marginally small. You should wear your shoes and set the saddle height and set-back and look at your reach again. Your photos look a bit similar to ones I took a few months ago, when I had all sorts of problems with a bike that was a bit small for me. I also wanted an endurance fit and ended up moving the saddle back quite a bit (c. 3-4cm behind KOPS) and getting a riser stem than reduced saddle to bar drop to about 3cm.

Once you are happy with seat height (probably 760+mm from BB given your inseam) and set-back (use either KOPS or "balance test" as a starting point), then look at a reach that will allow for comfortable relaxed shoulders, with upper arms at about 90 degrees to your torso and a 15 degree bend at the elbow. You may want a stem that is 10-20mm longer than current.
