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.
Kwa nafasi ya derailleur kapi gurudumu
Kwanza, porous spring msimamo kikomo inaweza kurekebisha nyuma mvutano kiasi kikubwa, kuboresha udhaifu wa kunyoosha dhaifu ya awali, na kufanya juu na chini mvutano mlolongo kati ya mwongozo gurudumu na cogs zaidi vya kutosha.
Pili, mawasiliano jino simu au kudhibiti jino namba kati mnyororo na cogs ya nyuma derailleur 17T ni zaidi wakati wa gear shifting, ni kama tu wa kubana kati na pande zote mbili za baadhi vijiti, kubwa kudhibiti lever, nguvu nguvu ya udhibiti.
Mwisho, baada ya kuunda upya ngome ya mzunguko Curve, umbali kati ya juu kuongoza gurudumu na cogs ni bora.
hatua za kusakinisha
1.Remove nyuma derailleur kapi gurudumu ngome: Ondoa hex parafujo upande wa chini ya ngome kapi gurudumu kwa kutumia No 2 hex wrench. (Asili ngome kapi gurudumu imeondolewa kwenye picha)
2.Remove hex parafujo, kuchukua nje ya awali ngome kapi gurudumu na spring. (Asili ngome kapi gurudumu imeondolewa kwenye picha)
3. 17T carbon fiber kapi gurudumu ngome, unaweza kuona 8 mashimo, alama ya 1 na 4 ni mvutano marekebisho shimo, na nyingine nne za kupunguza uzito. Mpango wa mwanzo mounting ni shimo 2 (mvutano: 4> 3> 2> 1)
4.Install mashimo kuchaguliwa spring mounting katika pini spring. chuma cha pua shimoni kwenye kapi ngome gurudumu lazima greased kabla ya ufungaji.
5.Push ngome kapi gurudumu ndani ya shimo la nyuma derailleur.
6.Rotating kapi gurudumu ngome, kuweka kapi gurudumu ngome kuzuia rebound kikomo screw katika derailleur nyuma.
7.Push ngome kapi gurudumu kikamilifu katika msingi wa derailleur nyuma.
8.Weka hex parafujo katika shimo upande wa chini ya derailleur nyuma kwa kutumia No 2 hex wrench.
9.Kaza parafujo.
10.Mara kwa mara mzunguko kapi gurudumu ngome, thibitisha rebound vizuri, ufungaji ni kamili.
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.
Pili, mawasiliano jino simu au kudhibiti jino namba kati mnyororo na cogs ya nyuma derailleur 17T ni zaidi wakati wa gear shifting, ni kama tu wa kubana kati na pande zote mbili za baadhi vijiti, kubwa kudhibiti lever, nguvu nguvu ya udhibiti.
Mwisho, baada ya kuunda upya ngome ya mzunguko Curve, umbali kati ya juu kuongoza gurudumu na cogs ni bora.
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.
