  • Some Russian guy did some great testing. The info comes from that. I'll dig it out if I can remeber it.
    I think it's still a good option on road, just not as clear cut as off road. And I think the new one when released will be again clear cut.

    The russian guys research also make the case that you need to consider dynamo too and its interaction with the light in question.

  • really interesting. Thanks for sharing.

  • Alee's piece on rim dynamos was also interesting:

    The only dynamo I've ever considered buying was the Velogical. It still makes good sense as a back-up lighting system (and extra light for descending), although expensive for that.

    It always surprises me that so few people who use dynamos for on-road ultras use rim rather than hub setups.

  • Dynamo 100% I think if you are trying to go fast you want to minimise the mental load.

    There's a lot to be said for that but, on the other hand, if there is advantage to be gained from saving the Watts, at some point the additional mental load of remembering to recharge becomes worth it.

    It's a bit like do I always follow my route because that's the easiest thing to do, or might I change it sometimes eg to go round a storm. It's easier mentally to follow the pink line but it might be faster to do the thinking.

  • There's a bunch a ways to deal with this problem. Go out and figure out what works best for you. Some people like batteries. Some people dig dynamos?

  • Interesting discussion on dynamo vs dyna-no setups. Think it will come down to budget for me this year at least, hope to have the convenience at some point though.

    It looks like we have been lucky and snagged a couple of Sverige Tempot places whilst being on the reserve list. What are people thinking/feeling/guessing is the likelihood of actually being able to travel abroad come July?

  • To me, it feels like being able to leave the country by then will be pretty likely. The concern seems to be the slow uptake of the vaccine on the continent. There's talk of Sweden having a vaccine passport programme I think I read?

  • Couldn’t find a thread dedicated to it, but Victoria Divide 550 starts tonight.

    Beware of Walmer bars :-)

  • Bars in Australia generally are warmer
