Re: Headset

If its A head (threadless), I'd be suprised if the star fangled washer had fallen down (normally they are quite tight). If it is, simply fit a new star fangled washer as Brucey suggests. If its the older quill type, normally you can 1. Put the stem bolt only (remove from stem) down the fork column a...

Re: Chains and Emulsifiers

Chain removal by breaking the chain OK for 8 speed or less, otherwise you will need to use the special joining links for 9+ speed (in theory tool free breaking/removal of the chain then possible - I say in theory as I rarely manage to push the links at the right angle to open). Joining lings also av...

Re: How safe is cycling?

Statistically, rural minor roads account for alot (half?) serious injuries/deaths, I do alot of riding on such roads and find it OK. If you wanted to allay family fears, you could get a top up course of on road cycle training (trainers listed on the CTC website somewhere). You might not need the tra...

Re: Whether this is a crack in my frame

I have seen cracks on metal frames and carbon forks (near the aluminium internal crown). Scratches can be fairly thin to very wide (your photo comes in the wery wide category in my book). Cracks are normally very thin, and also when looked at very closely, wiggly rather than pure straight. Most crac...

Re: Child Bike trailers. Shaken baby?

Worth checking instructions re tyre pressures. I vaguely recall (from working in a bike shop years ago) somewhere in Burly (or Chariot) instructions (not prominantly) it mentioned keep tyre pressures low (30psi?) to prevent it tipping over on uneven surfaces. Burley make them well. I saw a Burley ch...

Re: Stuffed inner tube

As someone who repairs bikes - usually with underinflated tubes - tubes often fail from the (underinflated) tyre slipping round the rim and dragging the innertube with it (except where the valve is fixed of course). One side of the valve the tube will be stretched tight, the other side all folded up...

Re: Blackburn FL1 lo-rider rack

I found with some hooks (I think Karrimore rather than Carradice) their grip was affected by wether you had the plate at the back, or at the front (ie on the in board or out board side). This difference tends to be where the hook is straight on one side, rather than curved on both sides like the hoo...

Re: What kind of box do you use?

I have not flown for a few years, but have used bike shop card board boxes, BA supplied big poly bag, and er nothing wrapped round it at all (for the return journey). Never had any problems. I prefer nothing or the BA poly bag options, as it is then unlikely to be stacked up with lots of other boxes...

Re: Full Length Summer Cycling Tights

I use Lusso - not as comfortable as other longs I use (I think its the cut) but quite OK with braces. I have not made extensive searches, but they are the only ones I can find/try that do not have a (thin) fleecy inner lining - these linings are far to hot for summer. The Lusso ones (made in UK by t...

Re: Lightweight lock for touring

The light weight lock question prompts me to ask something I often wondered - why has no one made a titanium "D" (or "U") lock yet? If there are worries about the 2 halves cold welding them selves (as in Ti treads), then at least 1 half could be titanium. Having once been asked t...

Re: Half link chains

Half link chains come into their own on single speeds with no so long traditional (not verticle) drop outs, you can get the chain lenght to with 1/2" (ie 1 link) rather than 1" (a pair of links) to get the chain tension right. Same benefit if your chainring/sprocket combination puts your w...

Re: Pedal Torque

You mentioned the pedals "just worked loose". If you rode them a while before noticing, you might have worn the crank threads slightly oversize? (silvery grease would be a givaway here, with ground metal in the grease) I have seen occasionally customers who didn't notice a loose (in crank)...
