Problem shifting into top and bottom gear
Hi,
My gears (105 10speed groupset with ultegra chain and cassette) have been running fine for months, but when I went for a ride last weekend the chain was struggling to get onto the rear cogs (was fine on my previous ride).
I fiddled with the barrel adjuster on the roadside and ended up being able to move up and down the cassette pretty smoothly, except I can't change into the top or bottom gears.
I don't know why this happened and to my knowledge the rear derailleur hasn't been knocked.
Any suggestions what might have gone wrong and how can I fix it?
Thanks.

agreed with above but if that doesn't help If its the smallest and biggest sprocket your having trouble with then it could be the limit screws need adjusting. Careful with that though, you don't want to getting it wrong you could overshift into your spokes.0

If the limit screws haven't been touched than leave them alone. The problem seems to be the classic one at this time of year in that the RD becomes unable to travel over its full travel because of muck and salt. Lube the RD pivot points and in the highest gear, pull down on the exposed gear cable while rotating the pedals. This should free up the RD sufficiently.0

I agree with this, but just in case, here's a pretty good vid to show you how to adjust the limit screws.

Thanks all, I'll give try cleaning and lubing everything this weekend and see it it sorts the problem out.
Can I use my normal chain lube on the cables (Prolink Gold)? I've also got some GT85 and some Finish Line Wet lube in the shed too.0 -
