My expectations were not too big, but this site is just amazing good runner. Because I'm good 25km by bicycle road almost every day (to work) and especially in winter driving too much at night, I have "suffered" all kinds of rain, snow and slush conditions. For several years I had not a single Durchschrutscher in this dynamo - always uniformly strong light. To date, I would not have kept this technology for a tire driven dynamo possible. After maybe 4 years, the cap then read somewhat after and had to be replaced. The problems described in another reviewers with the cap I had in any way. If you want to do without a hub dynamo, I can recommend this very Dynamo. Incidentally, I had the Dynamo first on a mountain bike wheel and later on a Randonneur. Positive experiences were the same in each case.
(Sorry, something negative I have "unfortunately" not to report.)
