Re: Servicing a Shimano Dynamo Hub

....FWIW I am working on a modification to Shimano hubs which will a) be possible to carry out without taking the hub to bits and b) will allow the bearings to be regreased in situ and c) will not interfere with the normal operation of the hub. Obviously I shall carry out some trials on one of my h...

If that is case would not (hopefully large) cartridge bearings not require less manual labour in production?

Re: Rose joint vs CarryFreedom Lollypop elastomer?

The trouble is that rose joints aren't designed to come apart. So you still need someway to unhitch your trailer from your bike even if you use one.... my thinking was the rose hitch would fit over the cf hitch cylinder in same way as the lollipop....I am unsure whether some extra rotation axis is ...

Rose joint vs CarryFreedom Lollypop elastomer?

The 'Trailabout' trailer uses several rose joints to make a hitch and this made me wonder if anyone had tried replacing their CarryFreedom orange Lollipop elastomer with a rose-joint or built a similar hitch to the Carryfreedom but using a rose-joint(s) in place of the elasomer?

Re: nexelo lights, any knowledge of quality?

The lack of German translation would reinforce the Stzvo absence....only for the laisez-faire countries then?

Re: Servicing a Shimano Dynamo Hub

The above seems to stretch the definition of serviceable a bit......?
If they wanted to sell it as a servicable item to the masses surely they would not have made the electrical connections so vulnerable?

nexelo lights, any knowledge of quality?

The following looked an interesting value lamp on ebay: https://www.ebay.co.uk/itm/NEXELO-Dynamo-Front-Lamp-6V-2-4W-or-6V-3W-Bicycle-Bike-ECE-Homologation/392568670933?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 I tried asking the ebay seller if they meant Stzvo rather than ECE bu...

Re: Why do so few rack manufs imitate tubus' triangulation by making platform triangular?

...Because it makes it difficult to fit a rectangular load, such as a Carradice rack bag. I have a Tubus Vega hanging up redundant on the garage wall due to this ... I didn't think a carrier top that starts wider than a rack lamp (like Spanninga Duxos/ B&M topline etc) would need to narrow so m...

Why do so few rack manufs imitate tubus' triangulation by making platform triangular?

Why do so few rack manufs imitate tubus' triangulation by making the top platform triangular (like in Tubus Vega)?

it is presumably isn't patentable and is a very elegant minimalist solution to triangulation at lightweight?

Re: Hub Dynamo for winter commute.

Quickly looking at retail prices for big shielded(approx 7X mm) cartridge bearings, they seem double in price compared to the usual size, so surely not too much extra cost over smaller ones, and surely a cup and cone hub is more expensive to produce (more labour intensive?) so a could a shimano styl...

Re: Hub Dynamo for winter commute.

shimano do use cartridge bearings, but not usually in things like hubs or pedals. I suspect that to achieve the same load rating in the bearing, the cartridge bearings in hubs would have to be far bigger and heavier (and more expensive) than those which are used by many other manufacturers. ...
