Re: Hub gear for Moulton TSR2

for now, you can still buy the S7 gear rod set which includes the red plastic widget ('locating sleeve' in SRAM-speak), but it is amongst a dwindling selection of SRAM IGH parts. https://www.sjscycles.co.uk/sram-hub-gear-spares/ The five speed hub is similar in principle but the rods are different T...

Re: Shimano Alfine 8 home maintenance - where to start?

as I noted upthread, if that pawl was in some way faulty, the hub would slip in second gear as well as sixth. The pawl sees higher loads in second gear than in sixth, so is more likely to slip. The Di2 servo unit contains a potentiometer which has to behave perfectly in order for the gears to be acc...

Re: Disc brakes, hydraulic versus cable

current Hydro disc systems have a bladder or a diaphragm in the reservoir which is meant to accommodate volume changes in the system as the pads wear. In theory if the system is correctly bled out there is no air anywhere in the system, so inverting the bike oughtn't cause any problems. However duri...

Re: 2019 Criterium du Dauphine; spoilers if you've not seen the day before's coverage.

The final part of today's stage was run off in heavy rain, so heavy in fact that with mere minutes before the riders were expected to arrive, the road was flooded near the finish line. The course was set up so as to tempt riders into making a long breakaway attempt, but with so many rides so close o...

Re: Shimano Alfine 8 home maintenance - where to start?

Also, running without the motor connected made no difference when it was recently slipping badly in sixth (pre-jiggle). one possible (probable) reason for this was that the shift servo was wrongly positioned before the thing was disconnected. Unfortunately there is no way of knowing that the servo ...

Re: Team Sky is now Team INEOS

I heard that he had a cracked neck vertebrae, so as broken necks go it isn't that bad, but any such injury is bad enough I suppose. He lost 'two litres of blood, more or less' according to the doctors. That is quite a lot. They are optimistic about complete recovery, but he's expected to be in hospi...

Re: What are the chances?

The front pads both have a piece missing in similar places which struck me as odd. The rear pad failure may have been partly a result of rust on the backing plate - I rarely use the rear brake and these pads had been in for more than 3 years. The front pad damage is most likely to have been caused ...

Re: Ammaco CS250

IIRC the Ammaco CS250 has 3x7 gearing and uses a rear wheel with a screw-on freewheel. You can normally buy a bike like this new for about £200. On the plus side a new freewheel and chain won't be expensive to buy when it wears out; in regular use you should budget for a new freewheel and chain once...

Re: Hub gear for Moulton TSR2

word of warning; if you are sticking with a coaster brake then not only are the options somewhat less in number but when there are two nuts on the left side of the hub most often these are necessary to keep the bearings in adjustment. This means that whilst some rim brake hubs can be respaced narrow...

Re: What are the chances?

neither thing is as uncommon as it should be. If you check the manufacturer's recommendations, you will find that although the friction material is about 2.4mm thickness on new pads, they very rarely recommend that you wear very much more than half of it away before binning them. The chances of the ...

Re: Disc brakes, hydraulic versus cable

Thanks for the replies. I feel as if I'm teetering on the edge of an abyss here as all my other four road bikes are rim brakes. I'm looking at a bike for long road rides in all weather (well, wet weather certainly). At present the only thing pushing me to jump into the disc brake abyss is the dread...

Re: Best Bike (very) Overweight

I would go to a big bike warehouse like Halfords, decathlon, go outdoors even Argos as the returns policy is very generous and if something does break the minimum wage spanner monkies aren't going to quibble rather they will replace or refund.... they might also turn round and say 'used outwith the...

Re: Ammaco CS250

one way of looking at it is that for £75 you might get to find out if you like riding a bike to work or not before that bike falls apart or needs extensive repairs. One way or another we 'pay for our education' and £75 might be good value and you might not have a dead loss at the end of it either. I...

Re: Disc brakes, hydraulic versus cable

My two-pennoth; Hydro brakes have better modulation and (usually) better power too. They are mostly fairly reliable, also. But they can of course still suffer from all the same problems that can happen between the pads and disc (e.g. glazing, wear, contamination, etc etc), plus some others. Differen...

Re: 2019 Criterium du Dauphine; spoilers if you've not seen the day before's coverage.

Imagine riding in wind, rain, up and down mountains for 213km, crossing the finishing line, and then...… doing another 16km, about half of it climbing. D'oh! Well that was the layout of the stage today; a finishing loop based around St Michel de Maurienne. There are two hard stages (shorter with mor...
