G'day,
I always spend the least I can get away with on cycling glasses (& still look cool!).I reckon they are a disposable item, abit like tubes...ya use 'em then chuck 'em away. I reckon there is a dirrect correlation between how much I spend on glasses, against how long they will last. The more I spend, the quicker I'm likely to 'come off' & break them, sit on 'em, leave 'em in the sun & melt 'em, dog ate 'em etc etc......graph looks abit like this....more that $200...about 48 -72 hours.....$50.....2 years....You do the math!,
cheers,
Hitchy
