Tens of millions of TIG-welded MTB frames since 1985ish show that this is very rare.fastpedaller wrote: ↑26 Mar 2024, 9:20pm I'm slightly shocked as i have a Spa Tourer - have to give it a once-over, as I wouldn't have expected a crack on a Spa steel frame. Having seen the photo it appears the tube has cracked in the heat-affected zone...... is this a rare occurrence in a welded steel frame?

Re: Help removing child freewheel & chainstays bent on same bike - advice?
It looks like one of the super-cheap freewheels with no removal dogs for a tool. You have to undo the lockring (usually clockwise!) then the whole ting will come apart in an avalanche of ball bearings and springs. Chuck it all away and you will be left with a screw-on collar on the hub - remove that with a pipe wrench and you will be ready to fit a new one.

Re: Re-using an old 8-speed Campagnolo wheel
It's the other way round:
8 speed Campag uses a steel freehub body and low splines. 9S and up uses an aluminium body with deeper splines. An 8S sprocket will fit the later body but chew into the splines as the load is over a smaller area.

Re: Re-using an old 8-speed Campagnolo wheel
But that won't be for an older 8-speed hub with a steel axle.
There are also some hubs (like the Chorus 9s one I have) that had an intermediate axle size which only ran for a couple of years.

Re: Campag freehub failure
Shimano had the freehub design wrapped up with patents so Campag had to go a different route. I agree it's a weaker design, but even Shimano adopted Campag's layout in Dura-Ace as it was lighter.pliptrot wrote: ↑9 Mar 2024, 8:06am The Campagnolo freehub is a poor design. Anyone know why Campag chose to put the drive side bearing even further inboard than on a freewheel hub? How ironic. In his book Upgrading Your Bicycle (1988) Frank Berto enthused about the Shimano freehub. At that time Campag were still only making freewheel type hubs (they were late to the party as usual, or perhaps all tied up with the Delta brake debacle) but I imagine he would have been unimpressed with what they came up with as a freehub. I imagine he would have excoriated Campag for their current offerings - extremely ugly components and with things like 9 tooth sprockets. Ergo levers always felt clunky and difficult compared to STI levers, and my 1994 Record chainset was not even slightly polished on the back side of the cranks. How the mighty fell.........

Re: Differences between Magura HS rim brakes
IIRC the cheaper ones have cost-reduced things like plastic levers. That said my bargain basement MT2 brakes have been flawless (just like my HS33 and HS77!)

Re: Differences between Magura HS rim brakes
Slaves are all the same, HS11 had different levers with longer blades. The mountings also varied with HS33 having all the QRs and braces, HS11 did not. However over the years they also changed the designs several times so exactly which HS33 etc you have can vary.

Re: New groupset for an old Galaxy
Honestly I would replace cables and especially outers and give everything a deep clean first. It's amazing how many supposedly worn out groupsets come back to life after new cabling.
That said, it's hard to get stuff new from Shimano as fashions move on and it's all become incompatible. I would be looking for an 8-9 speed with a triple, which means things like Microshift bar-end levers and old Shimano MTB rear mechs. Chains and cassettes are easily available new.
Other people will want all the whizzy modern 12 speed stuff but I still think 1x is a flawed idea, with lots of cross-chaining at the worst time. I'm not keen on fancy STI shifters on a tourer, preferring simple bombproof stuff. You might see things differently and have other priorities.

Re: Solar panel for usb charging?
Too true, you always need a small battery light.
However I disagree with your metaphor. To have Liz Truss levels of usefulness they would have to be actively bad for you rather than merely not improving the situation.

Put all that together and it's way heavier than the 200g extra of a dyno hub!

Re: Solar panel for usb charging?
I'm totally confused here. What's a solar generator if not a solar panel???Yatsushiro wrote: ↑20 Feb 2024, 12:07pm Last summer, I needed a way to keep my phone charged while I was outside a lot. I found out that a solar panel that's about 10-20 watts is good enough for charging a phone every day. It's small and works well for just this job. But I also wanted something a bit stronger for other stuff, so I looked into getting a solar generator too.
