29er wheels in orbea urrun 30 size s

@klaudynka - short answer: yes, 29" wheels can work fine at 158cm, but the thing to check isn't the wheels - it's the standover.
The Urrun only comes in 29", so it's not a choice you're making anyway - it's whether the size S fits you. A few honest points:
• Wheel size itself isn't the problem. 29ers roll over rough ground more easily and feel more stable - as a first experience they usually feel calmer, not scarier. Plenty of shorter riders get on fine with them on the right frame.
• Standover is the real number. From Orbea's geometry, the size S Urrun has a 775mm standover. At 158cm your inseam is likely somewhere around 71 - 75cm - which means straddling the top tube could be tight or touching. That's the measurement to check before anything else: measure your inseam (barefoot, book against the wall trick) and compare. You ideally want a few cm of clearance for when you have to bail off the saddle.
• Reach is fine. The S has a 410mm reach, which is sensibly short - you won't feel stretched out.
You're not alone in this, by the way - @Giox's post is worth a read: his wife is also 158cm and standover was exactly her worry when choosing a bike, more so than wheel size.
My advice: if there's an Orbea dealer anywhere near you, go swing a leg over a size S before ordering. Five seconds straddling the top tube will tell you more than any chart. If standover clears, the 29" wheels will be the least of your worries - you'll adapt to them within a ride or two.
What's your inseam measurement, if you know it? Happy to sanity-check it against the numbers.
@klaudynka - right, 74cm inseam against the S's 775mm standover gives you roughly 3.5cm of clearance. That's on the tight side of "comfortable" but not a dealbreaker - it's in the same ballpark as riders who report the Urrun's 445 mm chainstay and 66-degree head angle making it manageable at low speed, and the frame itself has a sloping top-tube, slacker fork angle, and longer reach which usually means the real-world pinch point (where you'd actually straddle it, feet flat) sits a touch lower than the nominal seat-tube-junction number implies.
So: workable, not generous. A few practical notes given that margin: • When you have to bail off the saddle in a hurry, you'll want to be dropping the seat and getting a foot down quickly rather than relying on loads of top-tube clearance - normal technique on any hardtail, just worth being deliberate about it at your margin.
• 3.5cm is enough that most riders manage fine, but it's exactly the kind of number where "measure at the shop" beats any spec sheet - your actual straddle stance, footwear and how you stand will shift it a few mm either way.
I couldn't pin an official S-specific standover figure beyond what's in our geometry data (775mm), so that's the number I'd stand behind rather than anything more precise - if you want it nailed to the mm, worth asking your Orbea dealer to confirm off the actual frame when you go try it.
Bottom line: at 74cm inseam, the S should work, but it's close enough that swinging a leg over one in person before you buy isn't just sensible - it's the deciding factor here.
Looks like that one snuck through twice @klaudynka - no bother, but I've already crunched the 74cm number in my last post: roughly 3.5cm of standover clearance on the S, which is workable but tight enough that trying one in person is the deciding factor, not the spec sheet.
Nothing new to add on the numbers - just let me know how the shop visit goes, or if there's a specific stockist near you and you want a hand finding one.
