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.
Maxaad bedeli wheel khafiyad derailleur
Waa midda koowaade, beeniyayna xadka booska guga dib u qabsato yaabaa xiisad inta badan, wanaajiyo itaaldarrada stretch daciif ah asalka ah, oo waxaad ka samaysaa ah kor iyo hoos silsilad xaalad kacsani ka dhex wheel guide iyo lidiin ka badan ayaa ku filan.
Marka labaad, tirada ilig xiriir ama gacanta tirada ilig u dhaxeeya silsilad iyo lidiin of 17T derailleur gadaal waa ka badan inta lagu guda jiro shaxdiisa marsho, waxa kaliya jeclahay in aan noqanayaa dhexe oo labada dhinac ah ulaha qaar ka mid ah, ugu weyn lever gacanta, xoog awoodda gacanta.
Ugu dambayn, ka dib uhabeynta qalooca wareeg qafis ee, masaafada u dhexeysa wheel guide sare iyo lidiin la soo hagaagtay.
tallaabooyinka rakibaadda
1. Rear daatay derailleur, ka saar qafis asalka wheel khafiyad, sida ku cad shaxanka (asalka qafis wheel khafiyad laga saaray, habka u qaadidda fadlan tixraac fahmi No.20)
2. Fadlan xaqiiji giraanta daawaha aluminium dhinac kala duwan dusha sare.
3. goomahooda ugu weyn bool.
4. Ku rakib dhaqe nylon si derailleur danbe.
5. kordhaya goomahooda ah bool bool ugu waaweyn, iyo codsan dufan.
6. Qaado qafis carbon 17T wheel fiber khafiyad, isticmaal No. 2 kiyaawo hex saarto daawaha xir baxay on dambe ee qafis wheel khafiyad ah.
7. Ka saar wheel khafiyad sare.
8. Ka dib markii ay ka saareen aan giraangirta khafiyad sare, rakibi handarraabbadeedii xarunta on dhabarka.
9. Ka hor inta rakibaadda bool ugu weyn, bool waa in si buuxda dufan leeyihiin.
10. Riix bool ugu weyn si buuxda salka qafis wheel khafiyad ah.
11. Fadlan xaqiiji dusha giraanta daawaha jeexdin galay bool ugu weyn, iyo dusha jeexdin ayaa dufan leeyihiin.
12. Fadlan xaqiiji diyaarad giraanta daawaha dibadda, iyo giraanta daawaha ayaa dufan leeyihiin.
13. Fadlan xaqiiji godka guga kordhaya ee derailleur danbe.
14. pin guga lays guga dalool ayaa sii kordhaya galay derailleur danbe.
15. Xaqiiji pin guga galay salka godka boos guga ah.
16. Ku rakib guga.
17. siman pin guga la godka on qafis wheel khafiyad ah
18. lagu calaameeyey ee 1 ilaa 4 waa xiisad godka sixitaanka, sii kordhaya default hore waa dalool 2. (xiisad: 4> 3> 2> 1)
19. qafis wheel khafiyad waxay si buuxda u tuujiyey derailleur danbe. xaqiijiyo in lays weyn bool.
20. No. 4 kiyaawo hex in la adkeeyo bool ugu weyn 4N.m.
21. Dib u celi giraangirta guide sare, gelin ah handarraabbadeedii khafiyad sare, laakiin aan ku adkeeyay.
22. kaltan uh qafis wheel khafiyad danbe ku celiska aheyd derailleur xadka block ah, ka soo riix bool topupper wheel khafiyad ah, ka xanibeen block xadka.
23. Adkay bool u wheel khafiyad sare.
24. rakibo waa dhameystiran.
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.
Marka labaad, tirada ilig xiriir ama gacanta tirada ilig u dhaxeeya silsilad iyo lidiin of 17T derailleur gadaal waa ka badan inta lagu guda jiro shaxdiisa marsho, waxa kaliya jeclahay in aan noqanayaa dhexe oo labada dhinac ah ulaha qaar ka mid ah, ugu weyn lever gacanta, xoog awoodda gacanta.
Ugu dambayn, ka dib uhabeynta qalooca wareeg qafis ee, masaafada u dhexeysa wheel guide sare iyo lidiin la soo hagaagtay.
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.
