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.
Mengapa menggantikan derailleur roda pulley
Pertama, berliang had kedudukan spring boleh menyesuaikan kembali ketegangan sebahagian besarnya, memperbaiki kelemahan regangan lemah asal, dan membuat atas dan ke bawah ketegangan rantaian antara roda panduan dan salah satu alat lebih secukupnya.
Kedua, nombor telefon gigi atau kawalan jumlah gigi antara rantai dan salah satu alat daripada belakang derailleur 17T adalah lebih semasa gear anjakan, ia hanya suka picit tengah dan kedua-dua belah beberapa kayu, yang lebih besar tuil kawalan, semakin kuat kuasa kawalan.
Akhir sekali, selepas mereka bentuk semula keluk putaran sangkar ini, jarak antara roda panduan atas dan salah satu alat bertambah baik.
langkah-langkah pemasangan
1. Rear derailleur penguraian, keluarkan asal roda pulley sangkar, seperti yang ditunjukkan dalam rajah (asal roda pulley sangkar telah dikeluarkan, kaedah penyingkiran sila rujuk untuk memikirkan No.20)
2. Sila sahkan aluminium aloi cincin permukaan sisi yang berbeza.
3. bolt utama gasket.
4. Pasang mesin basuh nilon untuk derailleur belakang.
5. Memasang gasket bolt utama dalam bolt, dan memohon gris.
6. Ambil 17T karbon roda serat pulley sangkar, gunakan No. 2 hex sepana keluarkan aloi skru pada bahagian belakang sangkar roda pulley.
7. Keluarkan roda pulley atas.
8. Selepas mengeluarkan roda pulley atas, memasang bolt pusat di belakang.
9. Sebelum pemasangan bolt utama, bolt perlu lancar sepenuhnya.
10. Tolak bolt utama sepenuhnya pada pangkal sangkar roda pulley.
11. Sila pastikan permukaan alur aloi cincin ke dalam bolt utama, dan permukaan alur telah disapu mentega.
12. Sila sahkan pesawat aloi cincin luar, dan cincin aloi telah disapu mentega.
13. Sila sahkan pemasangan lubang musim bunga di derailleur belakang.
14. spring pin penjajaran spring lubang pelekap ke derailleur belakang.
15. Sahkan pin spring ke pangkal lubang kedudukan musim bunga.
16. Pasang musim bunga.
17. Sejajar pin musim bunga dengan lubang pada sangkar roda pulley
18. Marked dalam 1 hingga 4 adalah ketegangan lubang pelarasan, pemasangan lalai awal adalah lubang 2. (ketegangan: 4> 3> 2> 1)
19. roda sangkar pulley ditekan sepenuhnya ke dalam derailleur belakang. mengesahkan penjajaran bolt utama.
20. No. 4 hex sepana untuk mengetatkan bolt utama untuk 4N.m.
21. Tetapkan semula roda panduan atas, memasukkan bolt pulley atas, tetapi tidak diperketatkan.
22. berputar sangkar roda pulley ke belakang blok had derailleur pemulihan, tekan topupper roda pulley bolt keluar, menyekat blok had.
23. Ketatkan atas roda pulley bolt.
24. Pemasangan selesai.
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.
Kedua, nombor telefon gigi atau kawalan jumlah gigi antara rantai dan salah satu alat daripada belakang derailleur 17T adalah lebih semasa gear anjakan, ia hanya suka picit tengah dan kedua-dua belah beberapa kayu, yang lebih besar tuil kawalan, semakin kuat kuasa kawalan.
Akhir sekali, selepas mereka bentuk semula keluk putaran sangkar ini, jarak antara roda panduan atas dan salah satu alat bertambah baik.
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.
