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.
He aha whakakapi derailleur wīra wira
Tuatahi, maiengi rohe tūranga puna taea whakarite hoki mānukanuka te nuinga, te whakapai ake i te ngoikore o te totoro ngoikore taketake, ka hanga i te ake, me te iho mekameka mānukanuka i waenganui i aratohu wira me cogs nui atu tōtika.
Tuarua, ko te tau whakapā niho mana ranei tau niho i waenganui i mekameka me cogs o muri 17T derailleur he atu i roto i taputapu whakaneke, tika rite reira ki whakawiri te waenganui, me te rua taha o etahi rakau, te nui te hua mana, te kaha te mana mana.
Heoi, i muri i waihanga anō ānau hurihanga o te whare herehere, ake te tawhiti i waenganui i runga wira aratohu me nga cogs te.
kaupae tāutanga
1. Rear derailleur whāwehe, tango i te whare herehere wīra wira taketake, rite whakaaturia i roto i te ahua (i taketake whare herehere wīra wira kua nekehia, tikanga tango tirohia ki te feruri No.20)
2. Tena whakaū i te mata taha rerekē konumohe koranu mowhiti.
3. Ko te gasket tutaki matua.
4. Tāuta te mōria nairona ki te derailleur muri.
5. Whakapuru te gasket tutaki matua i roto i te tutaki, me te tono te hinu.
6. Tangohia te 17T waro whare herehere muka wīra wira, te whakamahi i No. 2 hex wāwāhi tango koranu ng μcrank atu i runga i te hoki o te whare herehere wīra wira.
7. Tangohia runga wira wīra.
8. I muri i te tango i te wira wīra o runga, tāuta te raka pokapū i runga i te hoki.
9. I mua tāutanga te tutaki matua, kia tino hinu te tutaki.
10. Neke te tutaki matua tino i roto i te turanga o te whare herehere wīra wira.
11. Tena whakaū i te mata haehae koranu mowhiti ki te tutaki matua, a kua te hinu haehae mata.
12. Tena whakaū i te rererangi koranu mowhiti waho, a ka kua te hinu te mowhiti koranu.
13. Tena whakaū i te puna poka ekeeke i derailleur muri.
14. Ko te puna titi tīaroaro puna ekeeke rua ki te derailleur muri.
15. Whakaū te titi puna ki te turanga o te poka puna tūnga.
16. Tāuta te puna.
17. whakahāngai te titi puna ki te poka ki runga ki te whare herehere wīra wira
18. Tohua i roto i te 1 ki te 4, ko te mānukanuka whakarerekētanga poka, te taunoa ekeeke tuatahi he poka 2. (mānukanuka: 4> 3> 2> 1)
19. Ko te whare herehere wira wīra tino aki ki te derailleur muri. whakaū i te tīaroaro tutaki matua.
20. No. 4 hex wāwāhi ki te whakakikī i te tutaki matua ki 4N.m.
21. Tautuhi te wira aratohu runga, kōkuhu i te raka wīra o runga, engari e kore e tightened.
22. Takahuri te whare herehere wīra wira ki muri derailleur fakaakeake poraka rohe, pēhi te topupper wīra wira tutaki i roto i, ārai i te poraka rohe.
23. whakakikī i te tutaki wīra wira runga.
He oti 24. te tāutanga.
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.
Tuarua, ko te tau whakapā niho mana ranei tau niho i waenganui i mekameka me cogs o muri 17T derailleur he atu i roto i taputapu whakaneke, tika rite reira ki whakawiri te waenganui, me te rua taha o etahi rakau, te nui te hua mana, te kaha te mana mana.
Heoi, i muri i waihanga anō ānau hurihanga o te whare herehere, ake te tawhiti i waenganui i runga wira aratohu me nga cogs te.
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.
