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.
Nahoana no hanoloana derailleur pulley kodia
Voalohany indrindra, porous lohataona toerana fetran'ny mety hanitsy indray fihenjanana amin'ny ankapobeny, hanatsarana ny fahalemen'ny malemy mihinjitra am-boalohany, ary manaova ny miakatra sy midina eo amin'ny mpitari-dalana rojo fifandirana kodiarana sy ny maina fotsiny ny ampy kokoa.
Faharoa, ny fifandraisana nify isan'ny na ny fanaraha-maso nify isa eo amin'ny rojo sy ny maina fotsiny ny any aoriana derailleur 17T dia mihoatra mandritra ny fitaovana mifindrafindra, dia toa ny fiantraikany ny afovoany sy ny lafiny roa kitay, ny lehibe kokoa ny fanaraha-maso fanoitra, ny matanjaka ny fanaraha-maso ny fahefana.
Farany, rehefa avy redesign ny tranom-borona ny fihodinan'ny curve, ny elanelana eo amin'ny mpitari-dalana ambony kodiarana sy ny maina fotsiny ny dia nihatsara.
fametrahana dingana
1.Remove ny kodiarana aoriana pulley derailleur tranom-borona: Esory ny hex visy amin'ny lafiny-pototry ny tranom-borona kodiarana pulley mampiasa No. 2 hex wrench. (Ny voalohany pulley kodiarana tranom-borona efa nesorina teo amin'ny sary)
2.Remove ny hex visy, alainao avy ao am-boalohany sy ny tranom-borona pulley kodiarana lohataona. (Ny voalohany pulley kodiarana tranom-borona efa nesorina teo amin'ny sary)
3. 17T karbaona fibre pulley kodiarana tranom-borona, hitanao 8 lavaka, voasoratra ao amin'ny 1 ka hatramin'ny 4 dia olana fanitsiana lavaka, ny iray kosa ho an'ny fampihenana ny lanjany efatra. Ny toerana misy anao fitomboan'ny voalohany dia lavaka 2. (fihenjanana: 4> 3> 2> 1)
4.Install ny lohataona voafantina fitomboan'ny lavaka teo am-pantsakana Pin. Ny vy Stainless-lavaka ny tranom-borona pulley kodiarana tokony nanosotra alohan'ny fametrahana.
5.Push ny pulley kodiarana tranom-borona tao an-lavaka ny derailleur aoriana.
6.Rotating pulley kodia tranom-borona, mametraka pulley kodia tranom-borona Hiverina fetra visy andian-tsoratra ao amin'ny derailleur aoriana.
7.Manosika ny pulley kodiarana tranom-borona feno ho ao an-pototry ny derailleur aoriana.
8.Ampidiro eto ny hex visy ho any amin'ny lavaka amin'ny lafiny-pototry ny aoriana derailleur mampiasa ny No. 2 hex wrench.
9.Mafy ny visy.
10.Miverimberina fihodinan'ny kodiarana pulley tranom-borona, manamafy ny Hiverina hampandeha tsara, ny fametrahana tanteraka.
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.
Faharoa, ny fifandraisana nify isan'ny na ny fanaraha-maso nify isa eo amin'ny rojo sy ny maina fotsiny ny any aoriana derailleur 17T dia mihoatra mandritra ny fitaovana mifindrafindra, dia toa ny fiantraikany ny afovoany sy ny lafiny roa kitay, ny lehibe kokoa ny fanaraha-maso fanoitra, ny matanjaka ny fanaraha-maso ny fahefana.
Farany, rehefa avy redesign ny tranom-borona ny fihodinan'ny curve, ny elanelana eo amin'ny mpitari-dalana ambony kodiarana sy ny maina fotsiny ny dia nihatsara.
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.
