Caute, nasiel som si takehoto kamosa. Rozumieme si akurat sa na nom tusim moc natahujem.

(Stravil som nejake tie hodiny chcekovanim videi a citanim ako najst ideal bike fit ale tusim ma ta rozmanitost teoretickej internetovej knowledge len matie, tak reku idem na to pocitovo :)

Chcel by som teda skratit dlzku predstavca, akurat tieto zavitove predstavce su uz zda sa out of fashion a tazko sa hlada co potrebujem resp. budem potrebovat ak sa rozhodnem dalej experimentovat..

A teda k veci moja dilema je dvojita:

/ aku dlzku predstavca zvolit ako pokus c.1 6cm? 8cm? mam vysku cca 172-173 cm

// ci ist touto cestou: https://ebay.to/2xY4rps
Alebo skor skusit konverziu https://ebay.to/2HyCvYL a na nu potom hladat co potrebujem

00000101000635640006356505595951018149390850976408514698

co tak skusit sklonit spicku sedla nizsie, nez mas teraz (z pohladu na foto ma normalne rozboleli koule .. ) a skusit vytiahnut predstavec o par mm vyssie ?

00000101000635640006356505595951018149390850976408511695

predstavec by som niešiel pod 8cm, bude sa to potom divne ovladat
ak chces
urcite jak pise ea nizsie vymen sedlovku za nejaku bez setbacku
mozno posun sedlo trochu dopredu, ale pozor
nemal by si tym kompenzovat to, ze mas proste "dlhsi" ram nez potrebujes

00000101000635640006356505595951018149390850976408511597

zrusit setback na sedlovke a compact handlebars .)
a vacsiu kazetu!

ten setback a rajdy su asi najschodnejsia cesta pri takomto bycikli! ale myslim ze to nieje az tak zle s tebou aj podla obrazka by som povedal ze to je dost ok

7 slov a 3 z toho v anglictine. ta zvysna slovencina to tam dost spati - naco sa s nou trapit?
bolo vobec niekedy zaujimave pisat cyklo zargon v anglictine?

000001010006356400063565055959510181493908509764085115970851238208512403

môj problém je, že ten slovenský nepoznám lebo všetko čo viem som sa naučila v eng
(ďalšia vec že 10+ rokov kvakam v práci anglicky denne a strada deformata)

Skusil som este zanalyzovat za pomoci jednej mobile app.. vyzera ze fittujem tie intervaly.. aj ked otazna je presnost.. zalezi to ako su tam umiestnene tie body.. uz mala odchylka dava celkom velke rozdiely.. vo vysledku nejak takto.. (.. a ano som tucniak .)

FIT SESSION SUMMARY

Your implied max knee angle of 149° falls within the suggested range of 136-151°, suggesting your current saddle height is sensible. (To achieve an implied max knee angle in the middle of this range would suggest lowering your saddle by 1.7cm).

Any adjustments you decide to make to your bike should be made in small increments (saddle up/down/fore/aft by 0.5cm max), checking each time that you feel comfortable, giving your body time to adjust.

Under no circumstances should you attempt to make an adjustment that exceeds the recommended limits set by the manufacturer of a particular component (eg. saddle rail or seat post limits).

Torso Angle 41
This is usually a trade off between comfort (and power output) vs increased aerodynamics. With a typical riding position on the hoods you might want to go as low as 33° for racing shorter distances or go up to 45° with rides of longer duration or when there is a lot of climbing involved. Bikes designed more with leisure in mind may encourage torso angles above 50°.

Max Knee Angle (implied) 149
136-151° is optimal for most people. Your flexibility is an important factor to consider. If you find yourself rolling your hips or pointing your feet more then your max knee angle is probably too large for you. If your priority is to maximise top end power, eg. as a sprinter, your optimal max knee angle may need to be lower than normal - however this may come with increased risk of knee injury.

Min Knee Angle (implied) 76
70-78° is sensible. If you find this is on the small side yet the max knee angle is on the large side, it could be that your crank arm is too long. Conversely if you find this is on the large side yet the max knee angle is on the small side, it could be that your crank arm is too short.

Knee Angle (as pictured) 109
We don't make any suggestions based on this angle but see FAQs for info on how to use this to verify other angles.

Min Hip Angle (implied) 66
This is most relevant when in the tuck position. You should be careful not to cramp yourself excessively, hence reducing power and comfort. For very flexible people, 35-40° may be a good target to aim for when in the tuck position. If you are not particularly flexible 45-55° is a better target, especially for rides of long duration. In particular, triathletes should note that enduring a long period with an overly tight hip angle will negatively impact their run performance.

Shoulder Angle 86
For performance oriented cyclists we suggest a target range of 75-90° for a typical 'on the hoods' position. You will probably dip below this if riding on the bar tops or if your bike is designed more with leisure in mind.

Pedal Axle to Knee Front 8.4
For seat tube angles 71-74°, it is normally a reasonable starting place to target having the knee front (bony bit just below the knee cap) directly above the pedal axle. For steeper seat tube angles, expect the knee front to go beyond the pedal axle

Saddle Tip to B.Bracket 6
UCI rules stipulate that this should be no less than 5cm, but this is not relevant for most people and this condition is often breached with the aggressive set up of many tri focused bikes

Saddle To Handlebar Drop 5
This is governed by several factors and there is no suggested range. For those with long legs relative to the frame stack or for bikes with aggressively low front ends, a large drop may be inevitable. How comfortable this is will depend on your conditioning and power output - your legs help to support more of your weight as your power output increases. Some elite riders prefer the extra control they can feel with a small frame plus long stem setup and are fine with a large drop (and low torso angle). Nevertheless, for most people, with a regular road bike set up, drops of more than 13cm are normally best avoided.

Seat Tube Angle 75
Classic road bike geometry is in the 71-74° range, time trial or triathlon focused bikes are typically in the 74-80° range. A steeper angle facilitates a tuck position that naturally rotates the rider position forwards, giving greater comfort at lower torso angles.

s prihliadnutim na fotku, stale plati, ze tie handlebars maju dlhy reach (je to taky, pre mna velmi neoblubeny, typ, ktory ma low drop a dlhy reach, vramci snahy o aero) a o tom svedcia aj tvoje ruky, ramena vytiahnute dopredu a klby viacmenej von.

zatial by som nesiel proti telu a jeho limitom a radsej stavil na pohodlie (krcnej chrbtice, ramien a krizov) a skratil ten reach a zmensil drop, ak by to slo.

s takto vystretymi rukami si koledujes o bolesti najma laktov a krku.

lakte necitim ale krk citim.. krize su take ambivalentne.. je tiez pravda ze ta appka tam ma 30 sec samospust a steloval som do tej pozicie tak narychlo cize nie je to mozno uplne ta optimal pozicia v ktorej sedim aspon pocitovo nevnimam ze by som mal cely cas takto vystrete ruky ale urcite smerodatne ze nieco treba robit s tym reachom..

00000101000635640006356505595951018149390850976408511003085110250851140008512385

krk citis lebo nie si zvyknuty..

00000101000635640006356505595951018149390850976408510458

tvoj handlebar ma velky reach. osobne nedoporucujem skracovat predstavec, ale ist do compact handlebaru s kratkym reachom. ak prilis skratis predstavec, bicykel bude prilis vratky a budes riskovat, ze ti predne koleso na nejakom hrbolci utecie.

0000010100063564000635650559595101814939085097640851045808512386

imho vraktost bicykla nezalezi od predstavca ale od polomeru otacania, bezne jazdim bez drzania rajd ako by dlzka predstavca v tom pripade ovplyvnila jazdu? nijako...cele to zalezi ako su od seba vzdialene kolesa tiez od fork rake a headtube angle...to ako mas dlhy stem akurat ovplyvni tvoje ovladanie bycikla a ako je prenesene tazisko ci viac v predu alebo vzadu.

0000010100063564000635650559595101814939085097640851045808510951

good point aj ked na tej fotke je to trocha z uhlu tak sa to zda enormne dlhe.. kazdopadne stoji za uvazenie..

00000101000635640006356505595951018149390850976408510015

co ja viem tak ja mam 169 a mam 52 a predstavec 110 a este k tomu mam viac slamnuty stem...cize ak mas nejake problemy a bolesti (tj si menaj flexibilny) treba cvicit a zlepsit inak si myslim ze by si si na to mohol zvyknut a malo by to byt ok. mozno tiez nebolo by zle zobrat viac compact handlebars, drop je strasne nizko.

ak je toto tvoj prvy cestny bike a predtym si jazdil biky kde si bol viac vystrety tak opravene si mozes mysliet ze to je moc natiahnute ale na ceste je to tak a este core strength je dolezita.

no moze byt, musim to este otestovat dlhsim jazdenim
