I realise this had been done quite a bit recently but after reading the threads I am now more confused that ever.
My girlfriend would like pannier racks for her bike (Giant Yukon Women’s 16”) but it does not appear to have rack mounts as it has disk brakes. Previously she would just carry her stuff in a rucksack but she is now working between 2 offices in the city and has to carry a laptop and papers on top of the usual change of clothes, towel and lunch so is now finding a rucksack uncomfortable.
With a change of wheels her bike is used at the weekends off-road so a rack that could be removed fairly easily would be a bonus.
I have seen the Topeak racks that mount onto the seat tube which seems a reasonable option to me but don’t know if they are any good or how you connect panniers to them.
The next question is what panniers to go for? I want something that is big enough to fit her laptop 15” (regular business size) but not too big that they will get in her way or more importantly that she cannot overload with stuff that will then exceed the 7-9Kg capacity of the rack.
