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. wara derailleur dekompożizzjoni, neħħi l-gaġġa oriġinali rota taljola, kif muri fil-figura (gaġġa oriġinali rota taljola tneħħa, metodu tneħħija jekk jogħġbok irreferi għall-figura No.20)
2. Jekk jogħġbok ikkonferma l-aluminju ċirku liga superfiċje tan-naħa differenti.
3. L-siegla bolt prinċipali.
4. Installa il-washer najlon għall-derailleur wara.
5. Immuntar l siegla bolt prinċipali fil-bolt, u japplikaw grass.
6. Ħu l-gaġġa rota fibra taljola karbonju 17T, l-użu No 2 hex wrench neħħi liga kamin fuq wara tal-gaġġa rota taljola.
7. Neħħi rota taljola fuq.
8. Wara li tneħħi r-rota taljola fuq, jinstallaw l-boltijiet ċentru fuq id-dahar.
9. Qabel installazzjoni l-bolt prinċipali, l-bolt għandhom ikunu bix-xaħam kompletament.
10. Imbotta l-bolt prinċipali bis-sħiħ fil-bażi tal-gaġġa rota taljola.
11. Jekk jogħġbok ikkonferma l-wiċċ kanal ċirku liga fil-bolt prinċipali, u l-wiċċ kanal jkun bix-xaħam.
12. Jekk jogħġbok ikkonferma l-pjan ċirku liga barra, u l-ċirku liga ikun bix-xaħam.
13. Jekk jogħġbok ikkonferma l-rebbiegħa immuntar toqba fl derailleur wara.
14. Il-pin rebbiegħa rebbiegħa allinjament immuntar toqba fil-derailleur wara.
15. Ikkonferma l-pin rebbiegħa fil-bażi tat-toqba pożizzjonament rebbiegħa.
16. Installa l-rebbiegħa.
17. Allinjati il-labra rebbiegħa bil-toqba fuq il-gaġġa rota taljola
18. Immarkati f'1 sa 4 huwa toqba aġġustament tensjoni,-immuntar inizjali ta 'default toqba 2. (tensjoni: 4> 3> 2> 1)
19. Il-gaġeġ rota taljola ippressat għal kollox fil-derailleur wara. jikkonferma l-allinjament bolt prinċipali.
20. Nru 4 wrench hex biex jissikkaw l-bolt prinċipali li 4N.m.
21. Irrisettja-rota gwida fuq, daħħal l-boltijiet taljola fuq, iżda mhux issikkati.
22. Rotatriċi-gaġġa rota taljola biex limitu blokk rebound derailleur wara, agħfas il-topupper bolt rota taljola barra, jimblokka l-blokk limitu.
23. Issikka l-vit rota taljola fuq.
24. 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.
