Re: New auto Scottoiler

This seems to be a solution looking for a problem it wont clean the chain, just adds oil. Hmm, I'm not sure. Judging by the number of "what chain oil" threads there's certainly a desire for a method of having a perfect chain lubricant. I like the Ultimate Bike Solution stuff because it's ...

Re: How does a bicycle stay upright?

Anyone who says that it's "definitely" or "definitely not" to do with X is almost certainly wrong.

Re: Suggestions for children's helmets?

Thanks. We already have a trailer (an excellent Chariot) but the seat will be for the quick trip to the nursery and things like that. I hadn't really considered how important weight is. We'll try our local Evans but it's not that big so perhaps the bigger Halfords will be worth a visit (shudder). At...

Suggestions for children's helmets?

I'll soon be nipping down the shops to buy a helmet for my 1 year old. Its main purpose will be to help if the bike topples over while he's still strapped in his seat (it's happened to a few people I know!) Other than a good fit, is there anything I should be looking out for in the shops? Or are chi...

Re: New Route Planner

I've done a bunch of work today on the GPS downloads: [list] [*]TCX should now work properly on Garmins - I've tested it on BaseCamp and Training Center and it works fine, though I don't have a new Garmin unit to test with; ... Oh, amazing. I'll have to try it out. In the past I've done the route f...

Re: Pinion 18 gear system

Nice one Brucey. I like the idea of a gearbox bike, but I've seen precisely none in the wild, so I doubt they've been very successful. I see that Nicolai mountain bikes do a hardtail with Pinion gearbox . They use a belt drive; I don't know how that answers your question about chain forces. Nicolai ...

Re: Brake Block Terminology

What, so you disagree with CJ? It's not so logical and simple after all, then. From one of my posts up thread:- Some people make issues out of nothing. The trailing end/part/edge is the rear of the brake pad/block as the rim passes it in the normal/forward direction of travel. That to me is a logic...

Re: Brake Block Terminology

Front=leading=toe rear=trailing=heel So the opposite of what CJ recommends? i.e. Front (of the bike)=trailing (of the pad)=toe. But then earlier on you agree with CJ (unless I'm misinterpreting you): The trailing end/part/edge is the rear of the brake pad/block as the rim passes it in the normal/fo...

Re: Front derailleur will not change onto largest (52) ri

I'm reluctant to move the stop as Itry to work on things like this by a process of elimination if it ain't broke don't ( try) to fix it. But something is broke, so something needs fixing. And how can you do things by process of elimination if you're not starting at one of the most basic points? Mov...

Re: Front derailleur will not change onto largest (52) ri

Ignore the cable for now. Try pushing the derailleur by hand, as others have suggested.

You seem to be "ruling things out" without trying them first. Thought exercises only get you so far.

Re: Snapped Presta

Ah, so the nut prevents the valve from disappearing into the tube? I can see how that could be a problem the next time I need to add a load of air.

I'll also check to see if it's a removable core. Good idea, thanks.

Snapped Presta

I was just doing the final prep before heading out on a ride, pumped up the tyres and snapped the little nut and some of the stem off the presta valve on the rear tyre. It now looks like a narrow Schrader. The valve still worked (both letting air in and not letting air out), and I couldn't be bother...

Re: Electric gear shifting?

I'd suggest that problem is best addressed by... better barrel adjusters ... :roll: :wink: You're almost certainly correct. My previous ones didn't have a problem, and I don't have the heart to undo all the cables again (I hate doing gears). It would be somewhat cheaper to fix than a whole Di2 syst...
