Great Product and Comfort

In the past I tested a lot of different saddles due to saddle pressure problems and cut outs that didn’t work for me. At the end of this time consuming and quite costly process I decided to give Posedla a try (not just because I wanted to support a small, courageous company, but also because the concept and design of the saddle seemed convincing to me). The experience especially on longer rides was completely different and I’m really excited about the level of comfort and precise fit. Also the cut out is perfect for my needs. I’ve already ordered a second saddle for my other bike 😊

Sedlo Joyseat

Na sedle Joyseat jezdím cca 2 měsíce a pocit je z něho velmi dobrý. Ze začátku jsem si nějakým zásadním rozdílem, oproti mému sedlu Selle Italia, nebyl jistý ale čím více a déle jezdím, jsou pocity lepší a lepší. Ze začátku mne dokonce trochu "tlačily" sedací kosti ale teď už žádné nepohodlí necítím. Zatím jsem ale nejel jízdu delší než 2,5 hodiny. Sedlo hodnotím ale rozhodně velmi kladně.

Moje zkušenost s Joyseat

Cyklistiku jsem měl možnost vyzkoušet od amatérské až po poloprofesionální úrovně. Během této cesty se můj pohled na důležitost správného sedla výrazně změnil.

Ještě před 6–7 lety, kdy jsem jako závodník najel 17 tisíc kilometrů za sezónu, jsem sedlo zas tak moc neřešil. Buď jsem měl šťastnou ruku při výběru, nebo dlouhé hodiny v sedle a obrovský návyk na jízdu vše vyřešily za mě.

Po 7 letech závodní éry, kdy byla bolest zadku a zad to poslední, co mě trápilo, mě to nakonec stejně dohnalo. Jak se mé životní priority měnily a roční nájezd klesal, otázka výběru sedla mě začala trápit čím dál tím víc. Návyk byl pryč a sedlo, které mi celý život vyhovovalo, už tak perfektní nebylo. Nekonečné poposedávání a nepohodlí. Prvních 60 kilometrů jsem si jízdu ještě užil, ale potom se to změnilo v trápení.

Jsem takový cyklistický svéráz, takže se rád držím „tradičních a ověřených“ věcí. Sedla jako Fizik Arione a Selle Italia SLR pro mě byla nesmrtelná klasika. 🙂 Každopádně tlak od mého zadku byl stále větší a já to musel začít řešit. Shodou okolností jsem měl možnost vyzkoušet a testovat první generaci Posedla Joyseat.

První jízdy byly bez problémů, ale stále to nebyl skutečný test na opravdu dlouhou distanc. Ten přišel až po nějaké době, kdy jsem se rozhodl vyrazit na 200km gravel závod Traka v Gironě s ročním nájezdem cca 500 km. Nebyl to nejlepší nápad ani nejpříjemnější zážitek, ale zadek byl rozhodně to poslední, co mě brzdilo. Nemusel jsem si vůbec poposedávat a v prudkých stoupáních při šlapání v sedle jsem měl maximální oporu.
Další test přišel na 24hodinovém závodě, do kterého jsem šel s přibližně 4500 najetými kilometry. Podařilo se mi ujet přes 500 km a znovu musím říct, že zadek bylo to poslední, co mě trápilo. Opět stabilní pozice, žádné opruzeniny ani otlaky. Tady jsem spíše trpěl na otlačené dlaně, takže možná i tomuto kontaktnímu bodu by se mohlo Posedla začit věnovat :)

Sedlo Joyseat by mi určitě pomohlo i z hlediska samotného výkonu v dobách, kdy jsem závodil. Mně však nesmírně pomohlo v tom, abych si na 100 % užil čas v sedle, který už není tak dlouhý, jaký bych si přál. Proto si myslím, že Joyseat není jen pro závodníky, ale naopak pro lidi, kteří si chtějí naplno užít ten omezený čas v sedle, který jim každodenní povinnosti dovolí. Je opravdu skvělé vědět, že člověk má v tomto ohledu o starost méně.

Díky!

s pozdravem Petr

Saddle from different world

I've been involved in the world of cycling, both amateur and semi-professional, for over 10 years, mostly on the road. For several years now, I’ve also been focused on bike fitting, and choosing the right saddle is a big topic for me. Over time, I've tried dozens of saddles—some were more comfortable, while on others, I couldn't even manage a few kilometers. Even though I found a saddle that mostly worked, there was always some small 'but,' and I had to adjust to the saddle. That's why the idea of the Joyseat saddle, which takes the opposite approach and adapts to the rider, appealed to me so much. From the very first ride, I had a feeling this was from another world, but I was still a bit skeptical from my previous experiences. 'When is it going to start hurting somewhere again?' I kept repeating to myself. I’ve been riding on the Joyseat for over 6 months now, and not a single problem has arisen—it provides support where it should and doesn't put pressure where it definitely shouldn't. The fact that it's a Czech brand is just the cherry on top for me. Keep it up and thanks! :)
