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.
Zašto zamijeniti mjenjač kolotur točka
Prvo, poroznih granica proljeće položaj mogao prilagoditi natrag napetost u velikoj mjeri, poboljšati slabost originalnih slabe protežu, i napraviti gore i dolje zategnutost lanca između vodiča točka i zupčanika mnogo više na adekvatan način.
Drugo, broj kontakt zub ili kontrolni broj zuba između lanca i zupčanika zadnjeg mjenjača 17T je još u toku prebacivanja brzina, samo da priklještite sredini i dvije strane neke štapiće, veća je kontrola poluga, jači je kontrola snage.
Na kraju, nakon redizajna krivu rotaciju kaveza, udaljenost između gornje vodič točka i zupčanika je poboljšana.
koraci instalacije
1.Uklonite zadnji mjenjač kolotura kavez točka: Uklonite hex vijak na strani baze remenice kaveza točka koristeći broj 2 hex ključ. (Originalni kavez remenice točka je uklonjena na fotografiji)
2.Uklonite hex vijak, izvadite originalnog kaveza kolotur točka i proljeće. (Originalni kavez remenice točka je uklonjena na fotografiji)
3. 17T karbonskih kavez vlakana kolotur točka, možete vidjeti 8 rupa, označen u 1 do 4 je podešavanje rupe napetosti, ostale četiri za smanjenje težine. Default početni montaža je rupa 2. (napetost: 4> 3> 2> 1)
4.Install odabrane proljeće montažne rupe na igle proljeće. vratilo od nehrđajućeg čelika na bubnju kavez točka treba podmazivati prije instalacije.
5.Push kavez kolotur točka u rupu zadnji mjenjač.
6.Rotating kolotur kavez točka, postavljanje kolotura točka kavez oporavak ograničenje vijak blok u zadnji mjenjač.
7.Gurnite kavez kolotur točka u potpunosti u bazu zadnji mjenjač.
8.Ubacite hex vijak u rupu na strani baze zadnji mjenjač pomoću broj 2 hex ključ.
9.Zategnite vijak.
10.Ponovljeno rotacija kavez kolotur točka, potvrdili oporavak glatko, instalacija je završena.
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.
Drugo, broj kontakt zub ili kontrolni broj zuba između lanca i zupčanika zadnjeg mjenjača 17T je još u toku prebacivanja brzina, samo da priklještite sredini i dvije strane neke štapiće, veća je kontrola poluga, jači je kontrola snage.
Na kraju, nakon redizajna krivu rotaciju kaveza, udaljenost između gornje vodič točka i zupčanika je poboljšana.
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.
