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.
Yog vim li cas hloov derailleur pulley log
Firstly, ntxeem tau caij nplooj ntoos hlav txoj hauj lwm tsis pub tshaj yuav kho rov qab nro lom zem ntau, ua kom cov tsis muaj zog uas yog thawj tsis muaj zog stretch, thiab ua tus tu thiab down saw nro ntawm daim ntawv qhia log thiab cogs ntau npaum li cas txaus.
Secondly, hu hniav tooj los yog tswj hniav tooj ntawm cov saw thiab cogs ntawm rear derailleur 17T yog ntau thaum lub sij hawm iav shifting, nws cia li xav de rau hauv nruab nrab thiab ob tog ntawm ib co nrog, tus loj dua cov tswj qib, lub zog cov tswj lub hwj chim.
Ntsig, tom qab kho lub tawb txoj kev tig nkhaus, qhov kev ncua deb ntawm sab sauv qhia log thiab lub cogs yog zoo tuaj.

7. Tshem tawm sab sauv pulley log.
8. Tom qab tshem tawm cov sab sauv pulley log, nruab ib lub center bolts nyob tom qab.
9. Ua ntej installation lub ntsiab ntsia liaj qhov rooj, cov ntsia liaj qhov rooj yuav tsum tau tag nrho greased.
10. Thawb lub ntsiab ntsia liaj qhov rooj nyob rau hauv lub hauv paus ntawm lub pulley log tawb.
11. Thov paub meej tias cov hlau nplhaib zawj nto rau hauv lub ntsiab ntsia liaj qhov rooj, thiab zawj nto tau greased.
12. Thov paub meej tias cov hlau nplhaib dav hlau sab nrauv, thiab cov hlau nplhaib tau greased.
13. Thov paub meej tias cov caij nplooj ntoos hlav mounting qhov nyob rau hauv rear derailleur.
14. Lub caij nplooj ntoos hlav pin kawm tuab si lug caij nplooj ntoos hlav mounting qhov mus rau hauv lub rear derailleur.
15. Paub meej tias lub caij nplooj ntoos hlav pin rau hauv lub hauv paus ntawm lub caij nplooj ntoos hlav tso qhov.
16. Nruab ib lub caij nplooj ntoos hlav.
17. kws dlhos lub caij nplooj ntoos hlav pin nrog lub qhov nyob rau hauv lub pulley log tawb
18. cim nyob rau hauv 1 mus rau 4 yog nro hloov qhov, lub neej ntawd thawj zaug mounting yog qhov 2. (nro: 4> 3> 2> 1)
19. Lub pulley log tawb siab nias rau hauv lub rear derailleur. paub meej tias lub ntsiab ntsia liaj qhov rooj kawm tuab si lug.
20. Tsis 4 hex ciaj ntswj kom ceev lub ntsiab ntsia liaj qhov rooj rau 4N.m.
21. Pib dua lub sab sauv qhia log, ntxig rau hauv lub pulley bolts, tab sis tsis nruj.
22. uake lub pulley log tawb rau rear derailleur thaws txwv thaiv, nias lub topupper pulley log ntsia liaj qhov rooj tawm, thaiv cov hlab cov kev txwv block.
23. Ceev cov sab sauv pulley log ntsia liaj qhov rooj.
24. Lub installation tag.
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.
Secondly, hu hniav tooj los yog tswj hniav tooj ntawm cov saw thiab cogs ntawm rear derailleur 17T yog ntau thaum lub sij hawm iav shifting, nws cia li xav de rau hauv nruab nrab thiab ob tog ntawm ib co nrog, tus loj dua cov tswj qib, lub zog cov tswj lub hwj chim.
Ntsig, tom qab kho lub tawb txoj kev tig nkhaus, qhov kev ncua deb ntawm sab sauv qhia log thiab lub cogs yog zoo tuaj.
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.
