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 katrol
Pertama, berpori batas posisi semi bisa menyesuaikan kembali ketegangan sebagian besar, meningkatkan kelemahan peregangan lemah asli, dan membuat atas dan ke bawah ketegangan rantai antara panduan roda dan roda jauh lebih memadai.
Kedua, nomor kontak gigi atau kontrol jumlah gigi antara rantai dan roda dari 17T derailleur belakang lebih selama pemindah gigi, itu hanya ingin mencubit tengah dan dua sisi beberapa tongkat, semakin besar tuas kontrol, semakin kuat daya kontrol.
Terakhir, setelah mendesain ulang kurva rotasi kandang ini, jarak antara roda panduan atas dan roda ditingkatkan.
langkah-langkah instalasi
1. Rear derailleur dekomposisi, menghilangkan kandang katrol roda asli, seperti yang ditunjukkan pada gambar (asli kandang katrol roda telah dihapus, metode penghapusan silakan merujuk untuk mencari No.20)
2. Harap konfirmasi aluminium alloy cincin permukaan sisi yang berbeda.
3. baut gasket utama.
4. Pasang mesin cuci nilon ke derailleur belakang.
5. Mount gasket baut utama di baut, dan menerapkan minyak.
6. Ambil 17T serat karbon katrol roda kandang, gunakan No 2 kunci hex menghapus paduan sekrup keluar di bagian belakang kandang katrol roda.
7. Hapus roda katrol atas.
8. Setelah menghapus roda katrol atas, instal baut tengah di bagian belakang.
9. Sebelum instalasi baut utama, baut harus gemuk sepenuhnya.
10. Dorong baut utama sepenuhnya di dasar kandang katrol roda.
11. Harap konfirmasi cincin paduan permukaan alur ke dalam baut utama, dan permukaan alur telah diminyaki.
12. Harap konfirmasi bidang cincin paduan luar, dan cincin paduan telah diminyaki.
13. Harap konfirmasi musim semi pemasangan lubang di derailleur belakang.
14. semi pin keselarasan semi pemasangan lubang ke dalam derailleur belakang.
15. Konfirmasi pin musim semi ke dasar lubang musim semi positioning.
16. Pasang musim semi.
17. Blok pin musim semi dengan lubang di kandang katrol roda
18. Ditandai di 1 sampai 4 ketegangan penyesuaian lubang, default pemasangan awal adalah lubang 2. (ketegangan: 4> 3> 2> 1)
19. katrol kandang roda sepenuhnya ditekan ke dalam derailleur belakang. mengkonfirmasi keselarasan baut utama.
20. Nomor 4 kunci hex untuk mengencangkan baut utama untuk 4N.m.
21. Atur panduan roda atas, masukkan baut pulley atas, tapi tidak diperketat.
22. Memutar kandang katrol roda untuk belakang derailleur Rebound blok batas, tekan topupper pulley roda baut keluar, memblokir blok batas.
23. Kencangkan pulley roda baut atas.
24. Instalasi 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, nomor kontak gigi atau kontrol jumlah gigi antara rantai dan roda dari 17T derailleur belakang lebih selama pemindah gigi, itu hanya ingin mencubit tengah dan dua sisi beberapa tongkat, semakin besar tuas kontrol, semakin kuat daya kontrol.
Terakhir, setelah mendesain ulang kurva rotasi kandang ini, jarak antara roda panduan atas dan roda ditingkatkan.
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.
