no clearer. Specifically the question is, did

a) the spoke pull out of the nipple or
b) the nipple pull through the rim?

Re: Which 9 speed triple for light tourer

all things being equal (even though it is a bigger jump), the 24 to 38 shift may go easier than the 28 to 38 shift. Shift-wise you might be better off with 28-39-48 or 28-38-46 or 26-38-48 something; (the idea is to avoid a situation where the chain is as likely to hook up on the big ring as the mid...

Re: Churches - interesting

no thread on a cycling forum about churches is complete without mention of the stained glass in St Giles church, Stoke Poges https://www.yarnstormpress.co.uk/.a/6a01a511ea58a3970c01bb086b96c6970d-450wi This dates from 1643, they say, and some think it shows a kind of bicycle.... cheers

Re: Ribble R872 disK spider issues

don't ride with the LH crank part-way on; it'll knacker everything. The crankset you have is designed to have clearance to a 130mm rear hub even if the chainstays are short. The wheelset you have is presumably 12x142 at the back and is not really meant for being fitted to a bike with short chainstay...

Re: Shimano Plastic Rim Tape

a rubber washer helps stop chafing but provides only very limited support (just as a rubber rim tape might). This means with a presta valve in a schrader-drilled rim inner wall, it works OK at low pressures but at high pressures the valve stem ( being unsupported) can still separate from the inner t...

Re: Topeak Super Chuck - Presta to Schrader Adapter

the whole point of this chuck is that it is fitted to a standard hose on a track pump (~5mm ID) so (if that is the question) no, you can't just fit a Schrader valve chuck to the back of this chuck and use it as an adaptor. https://www.sjscycles.co.uk/pumps/topeak-super-chuck-dual-valve-pump-connecto...

Re: A"cute bike" with an acute angle-sadly

OTOH as a tall and fairly powerful rider I prefer the reduced flex of a diamond frame for spirited riding or touring. Yeah, when I first moved here and had a go on cheapo damcykel, I was amazed at the level of frame flex, it felt like it was made of rubber bands. Better ones are, er, better, but if...

Re: "Gusset" under downtube

worth mentioning that before comparing frames with and without gussets, it is worth looking at the tube gauges/materials used, and the intended service. Colin hasn't said as much, but I'd imagine that extended rough-stuffing/hard use of spa prototypes may have revealed an advantage to having a gusse...

Re: Chain, cassette, chainring- what would you do?

its worth making the point that not all wear on chainrings and sprockets is necessarily 'bad', i.e. it is possible to lose material whilst preserving the tooth shape well enough. Hence my suggestion that you should have a go with an old chainring and see how it runs.

Increasing the number of leds just increases the power output from the dynohub to supply the connected load. :wink: from this site http://pilom.com/BicycleElectronics/DynamoCircuits.htm http://pilom.com/BicycleElectronics/MultiLedCompHub.gif worth noting that rear lights have a nominal power of 0.6...

Re: How should spokes sit in nipples to be right?

longer nipples are available with either longer threads or the same length threads as normal. The ones you get from DT and Sapim are often (usually?) the latter type, and are meant for rims that are thicker from the nipple seat to the rim ID. This means they are really for locally reinforced (thicke...

Re: Centaur 11 rear mech wobbly????

9s MTB stuff is normally OK, but bad cable routing (esp on full suspension bikes) and/or bad cable housing can easily spoil that. I've been running 9s for about twenty years now on MTBs and it has mostly been pretty good. They didn't think they'd get away with the same shift ratio in 10s though, so ...
