Sram Apex 1 11 Speed shifter issue

Hello, firstly sorry for my bad English
i'm from east of Turkey. There is no one can understand and solve my problem so i decided to register this forum and try to explain my problem. maybe someone can help me?
I have trek 920 bike. I Had barend shifters so i decided to change them. I bought sram apex hdr groupset last week. I installed all by instructions.

rear mech's limit screws and cable tension is fine but i can not switch to lowest gear (biggest chainring) shifter clicks and pushes rear mech fine but when i release my finger shifter clickng back. From smallest ring to the 10th ring everything works fine but at the last ring my shifter clics twice and instantly releasing cabe to secong big ring. i removed cable and without cable same thing happens. 11th speed clicks twice. im suffering from this issue. please help me you are my last hope.

I'm not sure I understand exactly what the problem is but could be two things. 1. Possibly your derailleur cable is not tight enough so that the largest cog (chainring?) even though it pulls enough to move the chain to the cog you have already used your last click for the 10th cog, 2. The limit screw on the spoke side needs to be loosened a bit to allow the derailleur to move towards the spokes slightly. Just guessing but try this.

Some of these may be obvious (sorry), but here is my checklist:

0. Make sure that you have enough chain links in your chain. Look at SRAM instructions to ensure you have enough "slack".
1. Make sure that the derailleur hanger (the metal part that the derailer fastens to) is not bent.
2. Make sure that you set cable tension at the slack (lowest tension) setting properly, with the chain on the smallest cog. There should be adequate tension on the cable when at the smallest cog.
3. Visually inspect where the chain in for each of the rear cogs. If the chain is aligned with the smallest gear, but becomes more and more off-center (jockey wheels don't shift the chain the full distance between cogs) perhaps you have a freewheel that is not compatible with the SRAM Apex? The cassette (number of speeds and manufacturer) needs to match the derailleur. Running an 11 speed cog with a 9 speed derailleur (or something less obvious) might be causing the problem.
4. Are your brifters a direct match (manufacturer, group type (that is Apex vs Force or Red), number of speeds) have to match. Yegah's point, above, illustrates this issue.

İyi şanşlar

A shifter with 11 gear locations has 10 clicks. Not sure if this helps. A common teething issue when setting up a shift system is having the shifter one shift location off WRT the cog set's location. Andy
