Default Re: Poor shifting when it comes to 6th to 9th gear

same problem with mine, nahirapan lang ako mag shift to large cogs specially from 5th to 4th or 6th to 5th. No problems when shifting from larger cogs to smaller cogs but there are times na minsan tumatalon din from smaller cogs kahit isang shift lang, kumbaga nilalaktawan nya yung isang gear.

Matagal ko ng problema yan simula ng nagpalit ako from 8 speed to 9 speed. Btw i'm using Deore 9spd cogs, SLX RD, alivio FD, FSA V-drive cranks & Deore shifter.
Naisip ko lang siguro na baka hindi compatible yung cranks & FD ko.

@mantush, FS = full suspension, HT = Hardtail. nung una mo bang ginagamit eh meron nang ganyang symptoms? kasi kung ngayon lang, baka may cable stretch na. bring it to a mech para ma-adjust.

1. Baka maxadong masikip/malakas yung tension ng RD mo, adjust sa may shifter and/or sa RD mismo
2. Baka clogged yung components mo at nabibigatan ibagsak
3. Baka cable stretch, I pa suri mo na lang sa suking LBS para ma adjust nila
4. Luma/ Di magandang klase yung Chain
5. Check mo cogs kung may nakaipit or may chip/tabingi
6. Check mo cable housing mo kugn may yupi
7. Check mo yung bolt sa RD kung may pigtas na cable na

good luck! ride safe! :D

to mantush
dalhin nyo na lang sa LBS mo yan, since sa start pa lang eh nag babad shifting na, baka hindi lang naayos ng maige ng bike mech yung pag seset up nya ng drivetrain mo... or hindi nya natono ng ayos yung RD mo....

anyway - you can check this out... 100 causes of bad shifting

enjoy your ride after that at wag ka sanang panghinaan ng loob :)

If you get the first few high gears shift perfectly and your cable checks out, you hangar is bent. Bring it to the LBS to straightened.

Default Re: Poor shifting when it comes to 6th to 9th gear

Assuming you are using Top Normal RD, the culprit maybe worn out cable housing, low derailleur spring tension (due to fatigue if you always left it on tension while not in use), or worn upper jockey wheel (this causes misalignment).. If any of these occurs, pre-adjusting cable tension would not solve the problem and it would create some misalignment in some degrees to any other cogs..

Try mo bawasan pakonti-konti yung tension then check mo yung shifting in-between adjustments, dun mo kalkalin sa knob sa dulo ng cable sa shifter.

tanong ko lang po guys.
wala po bang magiging problema sa shifting kung gumagamit ako ng 8 speed cogs tapos 9 speed yung shifter ko?

In the event that spring tension is the problem of the rd, is it possible to replace the spring or I have to replace the rd, specifically, SLX 10-spd 2011 model. Is the spring readily available in the lbs?

@cruxader27 iba yung spacing ng gearing kada indicated speed mapa derailleur o shifter man, pero if you continue to use it, wala namang problema, kelangan mo lang iexperiment at ihanap paano maishishift lahat, in my own experience, yung beater bike ko eh 6 cog on 8 shifte, may skip/dead na numbers pero naishishift naman lahat.

natural lang ba na matigas yung shifting from small chainring to larger chainring sa cranks?
