This is the fastest RD pulley system.
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.Remove qafis wheel khafiyad derailleur gadaal: saar fur hex ah dhinaca saldhigga of qafis wheel khafiyad isticmaalaya kiyaawe hex No. 2. (The qafis wheel khafiyad asalka ah laga saaray sawirka)
2.Remove fur hex ah, qaadan out of qafis wheel khafiyad asalka ah iyo guga. (The qafis wheel khafiyad asalka ah laga saaray sawirka)
3. 17T carbon qafis wheel fiber khafiyad, waxaad ka arki kartaa 8 godad, calaamadeeyay in 1 ilaa 4 waxaa xiisad godka sixitaanka, afarta kale ee loo yareeyo miisaanka. sii kordhaya hore default waa dalool 2. (xiisad: 4> 3> 2> 1)
4.Install godadka guga xushay sii kordhaya at musmaarradii guga. The usheeda dhexe ahama-steel on qafis wheel khafiyad waa in la dufan leeyihiin ka hor inta rakibaadda.
5.Push qafis wheel khafiyad galay godka derailleur danbe.
6.Rotating qafis wheel khafiyad, dejinta qafis wheel block xadka kubadii fur khafiyad in derailleur danbe.
7.Riix qafis wheel khafiyad ayaa si buuxda u galay salka derailleur danbe.
8.Geli fur hex galay godka dhinaca salka derailleur danbe la isticmaalayo kiyaawo hex ee No. 2.
9.Adkay fur ah.
10.Soo noqnoqda wareeg qafis wheel khafiyad, xaqiijin ku celiska aheyd habsami leh, 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.
