Hello Folks
I was wondering whether i could quiz you about an issue I am having with slipping gears.
When in the middle ring on the front and high gears on the back (the 2nd, 3rd& 4th smallest sprockets) the chain slips when pedaling with pressure.
• It's a new cassette and chain (both 9 speed)
• New cables
• The bike changes gear with no problems
• Pedals fine on in same gears when no force is applied
• Derailers line up with sprockets
I am at a loss as to what's causing it, and before it goes to the local bike shop wondered if i am not doing something obvious.
Any help would be much appreciated, thanks.

Did you change the middle ring?
Sounds like that'd be a good place to start looking.
try fiddling with the indexing
Checked the condition of the middle chainring?
I had the same problem. Replaced the front chainrings and no skipping 😀
Thanks folks i haven't checked the middle ring! as if felt like the back was the culprit!
I'll go and check that.

Had a similar thing last weekend - turned out to be the b-tension screw. The clearance looked OK but when I gave it a couple of turn the problem went away. I hope.
ive still got this problem i cant find it at all with the old gear on it was fine, i swapped to new cassette chain and rings and now its doing it . im lost too lol
Mick try your cable tension, if its two tight, it might be try to shift under load.
Let the cable off and wind back the adjuster and try again.
ive tried alsort paul . im getting wed on tues so the bike is away now til i get back 😉 i will give it some more fiddle time then when im not up to my ears in things to do lol
Just a quick update (for future searchers), replaced the middle ring and that has solved the issue.
Thanks for all the suggestions.
