A lot of us on the forum are uk based.
The issues we have sometimes is that we try and help using the information we have gathered over the years. As with all things Internet, half of it is just plain wrong. Even official service manuals of their time are not correct as they seem to change parts on a whim.
Any hybred bike will be difficult to get plain and clear information on. Even simple things like cables may have come from something completely different. That is just the way it is.
When guys try and help they are giving you the best information they can. We often get questions about similar things and any diagnosis online is going to be a best guess which is based on common faults with a model, standard fault finding protocol or similar experience.
Even if people have tried to help and the information that they have shared is wrong. Due to wrong information out in internetland, this often helps as it can eliminate things or lead you closer to getting a definitive answer. As frustrating as this can be you have had assistance from some of the most knowledgable and respected guys here.
Er, that's about it from me.
