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.
Kutheni indawo derailleur pulley wheel
Okokuqala, nciphisa spring isikhundla aneentunja ulungise umva kwempixano ubukhulu becala, ukuphucula yobulwelwe Kumgama original buthathaka, kwaye wenze amaqhosha aphezulu okanye asezantsi umxokelelwane ukungaqondani phakathi ivili sikhokelo kunye zinegalelo kakhulu ngokwaneleyo ngakumbi.
Okwesibini, inombolo yoqhagamshelwano izinyo okanye ulawulo inombolo izinyo phakathi chain kwaye zinegalelo ze diff derailleur 17T kakhulu ngexesha izixhobo ukutshintshwa, Kunjani nje songe oluphakathi kunye namacala ezimbini iinkuni, ubukhulu lever ulawulo, ngokuqina kwamandla yolawulo.
Okokugqibela, emva ngokutsha ujikelezo igophe ebuhlanti kaThixo, umgama phakathi ivili sikhokelo ongentla kwaye zinegalelo is ngcono.
izinyathelo zokufaka
1. yangasemva derailleur ukonakala, susa ebuhlanti pulley ivili yokuqala, njengoko kubonisiwe kulo mzobo (ebuhlanti pulley ivili yokuqala isusiwe, ukususwa indlela nceda jonga i KWeather No.20)
2. Kucelwa uqinisekise i-aluminiyamu ingxubevange ring ezahlukeneyo umphezulu ecaleni.
3. Eyona waqonda gasket.
4. Faka iqhoshana nenayiloni ukuya derailleur ngasemva.
5. Ayanda kwasiso gasket ephambili ethole, baze basebenzise grease.
6. Thatha ebuhlanti ifayibha pulley wheel 17T carbon, sebenzisa No. 2 hex utsalo ukususa ingxubevange ujije phezu ngasemva ebuhlanti pulley ivili.
7. Susa ivili pulley eliphezulu.
8. Emva kokuba ivili pulley eliphezulu, faka nezitshixo iziko ngasemva.
9. Phambi ufakelo kwasiso engundoqo, kwasiso kufuneka uyithambise ngokupheleleyo.
10. Lityhalele ethole ephambili ngokupheleleyo esisekweni ebuhlanti pulley ivili.
11. Nceda uqinisekise iringi ingxubevange groove komhlaba kulo ethole eziphambili, kunye groove umphezulu sele uyithambise.
12. Kucelwa uqinisekise ngaphandle-moya ring ingxubevange, kwaye umsesane ingxubevange iye uyithambise.
13. Nceda uqinisekise emthonjeni eqhubekayo umngxuma derailleur diff.
14. I-spring pin ulungelelwaniso spring ezifuna umngxuma kungena derailleur angasemva.
15. Qinisekisa emthonjeni pin kwi kwisiseko emngxunyeni spring positioning.
16. Faka emthonjeni.
17. ziyahambelana isikhonkwane entwasahlobo kunye emgodini ebuhlanti pulley ivili
18. uphawu ngo-1 ukuya ku-4 udla ngokuba kukuxabana uhlengahlengiso umngxuma, obandayo engagqibekanga yokuqala una 2. (kwempixano: 4> 3> 2> 1)
19. ikheji wheel pulley icinezelwe ngokupheleleyo derailleur angasemva. ukuqinisekisa ulungelelwaniso ethole engundoqo.
20. No. 4 hex utsalo ukuba nsinya ethole main 4N.m.
21. Cwangcisa i ivili sikhokelo eliphezulu, faka nezitshixo pulley ephezulu, kodwa hayi some.
22. Ukujikelezisa yindawo yokuhlala pulley ivili ukukhulisa derailleur nkobe umda block, cinezela ethole pulley ivili topupper ngaphandle, uvimba kwibloko umda.
23. Qinisa kwasiso pulley ivili eliphezulu.
24. I ufakelo epheleleyo.
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.
Okwesibini, inombolo yoqhagamshelwano izinyo okanye ulawulo inombolo izinyo phakathi chain kwaye zinegalelo ze diff derailleur 17T kakhulu ngexesha izixhobo ukutshintshwa, Kunjani nje songe oluphakathi kunye namacala ezimbini iinkuni, ubukhulu lever ulawulo, ngokuqina kwamandla yolawulo.
Okokugqibela, emva ngokutsha ujikelezo igophe ebuhlanti kaThixo, umgama phakathi ivili sikhokelo ongentla kwaye zinegalelo is ngcono.
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.
