    Do you know of anywhere in the UK that doesn't suffer from inclement weather? Of course I rode in the wet. I've never heard of an Audax being rescheduled due to rain...

    Do you actually think I was disagreeing with your post? I've certainly not made any comment about the conditions you ride in.......

    Not at all. I was simply pointing out that it's unreasonable to purchase wheels based upon a perception of fortuitous weather- albeit in a roundabout way.

    Fair enough, I never ride if there's rain threatening. Weather's pretty reliable where I live and riding mid-winter isn't feasible. That's pretty standard practice round here.

    I can think of one or two occasions in recent years where I've got caught out by the weather. And I've still managed about 11,000 road kilometres with nearly 170,000m ascent this year. So brake track wear is far less significant than fatigue - in my experience of having lived a few years in the semi-desert in Chile and now in western Switzerland.

    Now for 90 minutes on the turbo cos it's a bit chilly outside...!

    Ahhh right! Though that is exactly what I am planning on doing - getting some cheap, light wheels for dry weather! But rain days are sparse around here and I'm not too fussed about swapping wheels over so that isn't a problem.

    What I don't see the point in is spending a fortune on light wheels. The point about the cheap ones is that the rims are thin and the hubs poorly sealed. But when the weather is bad, you are hardly going to be that appreciative of the lightness of your wheels - they'll be heavy with water on them anyway so you might as well go for something more durable and heavier then anyway.

    I lived in Italy for over 20 years and rim wear was unheard of... then in the UK I realised what it meant... round here the roads are moist and dirty for 6 months every year... bad road engineering, meaning soil verges collapsing onto the roads does the rest. In switzerland, like in Italy, I am sure they add concrete blocks at the side of the tarmac to prevent this happening, round here there are too many roads and they are built on the cheap... kind of developing nation standard. They tarmac without worrying about the edges

    RR415 rims crack if the tension limit of 1100N is exceded or a rider much over 80kg is put on them (weight limit is 90kg rider+bike). Keep to these limits and they are fine. I use them personally and it it impoossible to avoid the potholes all the time I do not have cracking issues and neither have I on the wheels I have built with these rims. All the cracking issue will be down to one or both the above limits being exceeded, keep within the limits and they are fine rims, exceed them and they are not. These limits are stated on the rim decals.

    As for DT Swiss hub flanges cracking I suspect they may have a practical tension limit too but I do not know where it is as I hardly ever use these hubs.

    If you ride on kerbed roads all the time then your rims will last longer if you are like me and live in Suffolk you a have a plethora of roads with a lovely grinding paste on them to kill my rims then you might want to be a bit more choosey when to use your light weight rims, Stans 340, Kinlin XR-200, Dura Ace C24 e.t.c I certainly am.
    I have a wheelset with Kinlin XR-200 Rims while there is not a fantastic number of miles on them (maybe 3000 miles maybe more) they have a similar ammount to my RR415 wheelset. The XR-200 rims I ride in the dry only and the RR415 I use in all weathers. I can assure which ones have the most wear - the RR415's.

    Soft pads are the answer as has been stated many times before ecpecially if you take your wheels out in the wet.

    Nope, I would say that keeping one's pads and rims clean and regularly picking out any bits stuck in the pads is the main answer. Soft pads can help but if the rims are covered in grime and the pads have embedded grit/flint shards then rim life will be poor.
