This is the fastest RD pulley system.
17TS & 17TR installation tips:
1, due to increased offset by the oversized pulley system, please make sure your RD and frame are aligned and calibrated correctly.
2, please check the length of your chain. Here is how to calculate, chain should be 10-20mm longer than the RD at 0 tension (shown as the picture below) when rests on the smallest chainring and smallest cog.
3, to lower the requirements for chain length and RD/frame alignment, we introduce the new 16T pulley system, 17TS and 17TR. Compare with 17T, the power saving would be lowered by about 0.2 watts but increasing chain stability and shifting speed.
Għaliex jissostitwixxu derailleur roti taljola
L-ewwelnett, poruż limitu pożizzjoni rebbiegħa tista 'taġġusta lura tensjoni aktar, ittejjeb id-dgħjufija ta' medda dgħajfa oriġinali, u jagħmlu l-up u 'l isfel tensjoni katina bejn rota gwida u snien ħafna aktar adegwat.
It-tieni nett, in-numru tas-snien kuntatt jew kontroll numru snien bejn katina u snien tal 17T derailleur wara huwa aktar matul ċaqliq tagħmir, hija biss simili li oqros-nofs u żewġ naħat ta 'xi bsaten, l-akbar il-lieva ta' kontroll, l-aktar b'saħħitha l-poter ta 'kontroll.
Fl-aħħarnett, wara disinn mill-ġdid kurva rotazzjoni tal-gaġġa, il-distanza bejn rota gwida fuq u l-snien hija mtejba.
passi installazzjoni
1.Remove-gaġġa ta 'wara rota taljola derailleur: Neħħi vit hex fuq in-naħa tal-bażi tal-gaġġa rota taljola tuża hex wrench Nru 2. (Il-gaġeġ oriġinali rota taljola tneħħa fir-ritratt)
2.Remove-vit hex, jieħdu mill-gaġġa rota taljola oriġinali u fir-rebbiegħa. (Il-gaġeġ oriġinali rota taljola tneħħa fir-ritratt)
3. 17T karbonju gaġġa rota fibra taljola, tista 'tara 8 toqob, immarkati f'1 sa 4 toqba aġġustament tensjoni, il-erbgħa l-oħra għall jitnaqqas il-piż. Il-muntaġġ tal-bidu default toqba 2. (tensjoni: 4> 3> 2> 1)
4.Install-toqob tar-rebbiegħa magħżula immuntar fil-labar rebbiegħa. Ix-xaft istainless steel fuq il-gaġġa rota taljola għandhom jiġu bix-xaħam qabel l-istallazzjoni.
5.Push-gaġġa rota taljola fil-toqba ta derailleur wara.
6.Rotating gaġġa rota taljola, li jistabbilixxi tarjola gaġġa rota limitu qabża kamin blokk fil-derailleur wara.
7.Imbotta l-gaġġa rota taljola bis-sħiħ fil-bażi tal-derailleur wara.
8.Daħħal il-kamin hex fil-toqba fuq in-naħa tal-bażi tal-derailleur wara bl-użu Nru 2 hex wrench.
9.Issikka l-vit.
10.Ripetut rotazzjoni gaġġa rota taljola, tikkonferma l-rebound mingħajr xkiel, l-installazzjoni hija kompluta.
According to test result, increase the rear derailleur pulley wheel size could significantly decrease the friction between the chain plates caused by polygon effects during chain bending, and reduce the resistance for saving rider’s cycling power.
The chain is composed of several short pieces with an inch long, we could see the chain as one inch long with around one hundred and ten section lines, due to small diameter of turning circle, when the lines pass through standard 11T pulley wheel, it needs a certain angle to turn the transferring direction of chain for about 180° through two wheels, after increasing the pulley wheel size, the chain turning angle are decreased, so the loss of friction is less correspondingly. The results shows that 17T is a good balance point between weight and decreasing the polygon effects, To increase the size blindly will lead to arc decreasing not obvious, together with weight and volume adding. Compared with common 11T pulley wheel, the friction loss caused by polygon effects of chain could be decreased about 60%.
Besides, under the same transferring speed of chain, the axis rotation speed of 17T is slower for saving the self friction loss during bearing rotation, smaller cycle could also reduce the resistance of each turn rotation. To upgrade this ceramic bearing saves more power loss.
Faster gear shifts. firstly, porous spring position limit could adjust back tension largely, improve the weakness of original weak stretch, and make the up and down chain tension between guide wheel and cogs much more adequately.
It-tieni nett, in-numru tas-snien kuntatt jew kontroll numru snien bejn katina u snien tal 17T derailleur wara huwa aktar matul ċaqliq tagħmir, hija biss simili li oqros-nofs u żewġ naħat ta 'xi bsaten, l-akbar il-lieva ta' kontroll, l-aktar b'saħħitha l-poter ta 'kontroll.
Fl-aħħarnett, wara disinn mill-ġdid kurva rotazzjoni tal-gaġġa, il-distanza bejn rota gwida fuq u l-snien hija mtejba.
And we should also tell customer that the compatibility of 11-28T cogs, the length of chain is within the range of 405-410mm standard road bike chain stay, suggest using more than 114 links, but not too short chain, or it might lead to too large back tension and enlarge the tooth tip resistance between chain and pulley wheels. (In case customer just has short chain, suggesting install it to lowest tension of spring mounting hole).
It can faster SHIMANO system up and down gear to improve 20%-26%. save 2.4 watts more.
