Hrrm. I just tried to fit my new Ortlieb Ultimate 5 bar bag which turned out to not be fun. Some how the bag managed to stuff up my rear derailleur so now when I pedal it crunches and makes all sorts of noise. I think this is because the bag is quite large and got in the way of the derailleur cables coming out of the levers. I've spent the last 30 minutes trying to adjust the cables to get it working properly with no luck. I was planned to go on a mini-tour tomorrow morning but this has thrown a spanner in the works. It's really cold outside so not a good time to be trying to adjust the bike. Looks like I'll have to scrap my test tour due to mechanical issues before it has even begun I was really looking forward to it too.
(ED: As it happens Mainpeak also accidentally sent me a small mattress instead of a medium that I had ordered, i only just realised last night after picking it up yesterday afternoon. So it's probably for the best I had to postpone the trip).
For others out there, don't bother with a large sized bar bag with the STI version of the VWR. It's a pain in the backside. I should have listened to the advice I was given and gotten the smaller bar bag. I don't need 7L worth of capacity anyway, I just need to hold a bit of food and my personal items.
ED: I re-set the derailleur today and checked all the adjustment settings and cable tension. I managed to get it all back in order again. I re-installed the bar bag and it is still working so I am hoping that it just caused bit of stretch of the RD cable due to being bent out of the way to make room for the bag and won't be an issue from now on.
I also played around with the front rack and managed to get it set a bit better, the brake mech audibly taps on a part of the rack when depressing the lever in this configuration, but it doesn't interfere with the function of the brake so not a major issue. The rack actually can be bent outwards/inwards quite a bit to get a good clear fit on the forks. Such is one of the many benefits of a steel rack! here's tow configurations I played with:
Outer-outer = slight angle towards bike:
Inner-inner = slight angle away from bike:
The inner-inner looks better on the bike that it does in that photo, I think it's what I'll go with rather than mucking around with the Duo rack. Now I know how it is fitted it only takes 10-15 minutes to install/remove. I've taken the rack off again for now and will put it back on in a fortnight when hopefully I can try do my trip again with luck this time.
