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 remenice kolo
Prvo, porozna granica proljeće položaj može prilagoditi natrag napetost u velikoj mjeri, poboljšati slabost izvornom slabe protežu, i napraviti gore i dolje napetost lanca između vodećeg kotača i zupčanika mnogo više na odgovarajući način.
Drugo, broj kontakt zub ili kontrolni broj zuba između lanca i zupčanika od stražnjeg mjenjača 17T je još u toku je prijenos brzina, to je samo želio patiti srednji i dvije strane nekih štapića, veća upravljačka poluga, jača kontrola snage.
Na kraju, nakon što je redizajn kavezu rotacije krivulje, udaljenost između gornje vodilice kotača i zupčanika je poboljšana.
koraci za instalaciju
1.Remove stražnjeg kotača kavez mjenjača remenice: Uklonite hex vijak na strani baze kavez remenice kotača pomoću hex ključ broj 2. (Izvorni koloturnik kotača kavez je uklonjena i na slici)
2.Remove hex vijak, uzeti iz originalne remenice kotača kavez i proljeće. (Izvorni koloturnik kotača kavez je uklonjena i na slici)
3. 17T karbonskih vlakana koloturnik kotača kavez, možete vidjeti 8 rupa, označene u 1 do 4 je podešavanje napetosti rupu, a ostala četiri za smanjenje težine. Zadano početno Montaža je otvor 2 (napon: 4> 3> 2> 1)
4.Install je odabran opruga otvora za ugradnju na izvoru igle. Od nehrđajućeg čelika vratilo na remenice kotača kavez treba podmazati prije ugradnje.
5.Push kavez koloturnik kotača u rupu stražnji mjenjač.
6.Rotating remenice kotača kavez, postavljanje remenice kotača kavez oporavak granica vijak bloka u stražnji mjenjač.
7.Push kavez kolotura kotača do kraja u bazu stražnji mjenjač.
8.Umetnite hex vijak u rupu na strani baze stražnji mjenjač pomoću br 2 hex ključ.
9.Zategnite vijak.
10.Ponovljeni rotacija kolotura kotača kavez, 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 od stražnjeg mjenjača 17T je još u toku je prijenos brzina, to je samo želio patiti srednji i dvije strane nekih štapića, veća upravljačka poluga, jača kontrola snage.
Na kraju, nakon što je redizajn kavezu rotacije krivulje, udaljenost između gornje vodilice kotača 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.
