I have a Pinnacle Neon 3 Hybrid, Shimano Sora 9 speed cassette and 2 chainrings at the front.
The bike is 2 weeks old and I've cycled around 65 miles so far.
Chain ring has come off 3 times at the front 1st time was when on the big ring at front and I selected wrong direction on the chainwheel (ie moved it outward instead of inward to smaller chainring - think I was on smallest cog at back), so I put it down to possible user error.
Today, the chain came off inwards twice at the front when moving from the large front chain ring to the small one whilst in the large cog at the back.The chain went past the small chainring. I have read it isn't ideal to be changing like this but should it really be coming off like that?
My previous bike, also a Pinnacle Hybrid, had 3 chainrings and I never had 1 chain slip in 6 years.
I'll probably take it in to be checked but wondered if there's anything I can do to adjust and make it less likely before the 1st free service is due in a month.
There is chain rub when on the largest cog and smallest chainring. Is it worth adjusting the H screw on the front derailleur to prevent the chain flying off when moving inwards as above from large to small chainring, or is it more likely due to the fact I was going from large chainring to small chainring ("extreme gear") when in the smallest cog?
