Re: Cannondale Headset Expander Plug

If you have slackened the handle bar stem off first, and it still doesn't tighten, the top cap might be bottoming out on the top of the fork column, in which case you'll need an extra spacer under the top cap. If it needs an extra spacer, probably :- either the forks have been ridden loose since whe...

Re: Deore 510 9 speed chainrings on 8 speed FCM361 spider?

Yes it will work. There will be a slight (small) gap between the crank arm shoulder and the ring because 4 bolt 8 speed and 4 bolt 9 speed have the same bolt hole dimensions, BUT the cranks have slightly different shoulder dimensions, so you can't put an 8 speed ring on a 9 speed crank (I've tried i...

Re: Intentionally struck by vehicle - what recourse?

I'd say always worth reporting, even if no action is likely to be taken. If the police get quite a few reports of aggression from a particular vehicle, they might be more likely to have words if nothing else. One of our local CUK groups had a near/loud(horn)/fast over take which was clearly uneccesa...

Re: Front derailleur capabilities - source?

Don't forget model designs (esp cage depth) sometimes change over time, so "Sora" capacity may change over time depending on the age/cage design, Thus probably best to search by model number (stamped on the back of the inner cage plate). Modern Shimano cages are notably deeper than some ol...

Re: Child seat advice

Generally rear child seats come in 2 types. 1. These mount on a rear pannier rack which may/may not have to be specific to the child seat. To fit a pannier rack you will need a rigid (at the back at least) bike with no suspension. 2. These mount on a bracket that bolts on the seat tube of the bike f...

Re: Milano specialised mtb

I'd say it was early/mid 1990's, I was working in a LBS then, and I remember Exage came out at that time.

Re: Folding bikes - good Brompton alternatives?

Not forgetting to consider how you secure it before you ride. Dahons, Terns + clones clamp using a cam lever. Like wheel QR's you need to adjust the cam to clamp tightly. They do come out of adjustment, I'd say half the Dahons/Terns I see at work have been ridden with the folding clamps not tight (m...

Re: Quill stem to A head adapter frozen in steerer

Looking at the photo, I think the stem has a shim between the extension and the adaptor, in which case the adaptor is 22mm/1"size all the way to the top. If so you can remove the handle bar extension then drop the forks out of the frame (undo headset etc) allowing access to heat the fork column...

Re: Need to reposition front mech?

If you change from a 110 to 113 BB axles, you might have to (ideally) lower ther mech a bit. With the 113 BB the mech needs to swing further out (by 3mm) to get to the big ring. In swinging further out, it also swings further up, so now has become too high. The effect may be significant, it might no...

Re: Used bike description

Crank scratching, looks like from a derailled chain from a poorly adjusted front gear to me. I'd say in a crash the crank wouldn't get scratched like that as the pedal would take the brunt of that.

Re: Padded Cycling Shorts - What Do You Wear Under - How Often Do You Wash

What to wear underneath - nothing. Far more comfortable. How often to wash. If its really hot weather, after each day ride. If it is more normal weather, I recon after 2 day rides is OK as I don't sweat much at all. Occasionally on tour 3 days if washing/drying looks tricky due to weather contraints...

Re: Van Nicholas Yukon

Not sure what you mean by"carbon alloy" (as a metallurgist that's steel to me!), or do you mean carbon fiber? Feel the fork blades. Metal (steel, titanium or alumimium) will feel cold (conducts heat from your hand), carbon fiber does not so will feel warm(ish)/not cold. (I'm assuming not a...

Re: Ornamental displaying of a bike

The last few times (I don't go there that often) I have walked out of Paddington station, just past where the police van is uually parked at the top of the slope, there has been a Kirk bike locked to the railings by the road. No sure if it has been abandoned, or just gets left in the same place.
