PhD candidate at the Building Physics Section, KU Leuven

Damage in historical buildings is often moisture related and affects the building envelope as wel as valuable objects in the indoor environment. A correct assessment of the damage risk requires reliable simulation tools to predict the course of surface, indoor temperature and relative humidity conditions. This can only be done by simultaneously studying the moisture balance of the indoor and outdoor environment, the interaction with the HVAC-system and the hygrothermal behaviour of the building envelope.

My current PhD focusses on the influence of the outdoor environment and the hygrothermal behaviour of the building envelope. Currently I’m researching the effects of wind driven rain (WDR) on the moisture uptake and transport to the inside environment by using both experimental methods and numerical simulations.

comment What are the advantages of angling your saddle down?
Can you give the full reference to the paper in the British Journal of Sports Medicine so I can look it up? The link isn't working for me.

comment Croozer bike trailer optimalisation for less tire detoriation
I make some close-up pictures this evening when I get home and add them to the question. @everyone you all post different approaches, can someone make/edit an answer to include them all so others with the same issue can find a consistent solution? I'm also not yet convinced of all proposed options.

comment Croozer bike trailer optimalisation for less tire detoriation
The problem only occured once we started to go on longer trips with this trailer and doing multiple descends. So I think that there is a mechanism that comes into play when going downhill and braking. But I can't put a finger on that how that will work.

I can switch the wheels. This way the direction of the tire is switched automaticly. So it helps a bit (that is also what we tried on holiday, but it didn't help that much, see the pictures).

So you would suggest to go for a single axis (running from one wheel to the other). Any ideas how I could make something like that? Can you also elaborate on your drawing which direction the trailer is going, which forces act on the wheels to get them in this stance?

Thank you for the reference to a good tire manufacturer. However I don't only want to trust on the quality of the tire but reduce the chance on wear too.

comment Croozer bike trailer optimalisation for less tire detoriation
I added pictures of the wear to the question. The wheels run true on their axle, however, there is a little bit of play on the axle when assembled in the cart (see picture in the question about that). The question is, how do I fix this?

Added details about the axle and wear. There is indeed some play on the axle. Any ideas how I can make some adjustments to make the forces on the tires smaller so that they wear slower?

@ShemSeger it is indeed a coil sprint on the trailer arm. Due to this the trailer doesn't respond immediately to the bike. Which results in problems when going downhill with some speed. I think that due to this there is a sort of braking force acting on the tires of the chariot.

About riding smoothly. Will it help if I remove the suspension between chariot and bike? I noticed going downhill that the chariot tended to wobble a bit.

I will add some pictures tomorrow (when there is light enough to take them) of the worn tires.

Tire pressure is the recommended maximum pressure (4 bar ~ 60 Psi).

comment How to check for aged/deteriorated weel rims
Is there a way to measure what is dangerously thin, with limited amount of tools? Is there a minimum thickness depending on the material used? That would be a useful addition to your already good answer.
