Re: Birmingham follows Bruges.

Hi
You can't ride a bike (or push one) in historic Venice. You can ride on mainland Venice but you have to leave bikes on the mainland at somewhere like the Venezia-Mestre railway station, in Trento street. Mild thread drift, but it might be of interest to some

Hi There's a picture of the headset stack here (link) The upper and lower head tube races are incorporated in your frame design and won't be present. The spacers are fitted between the upper bearing cover (labelled "seal") and the handlebar stem. The crown race is sometimes incorporated in...

Re: BLACK ICE & How to stay safe road riding in winter.

Hi I'm just after tips if I'm stubborn enough to say I'm going out on my road bike (the only bike I own) for a long weekend ride over beautiful hills in the sun and near freezing apart from going on main roads as let's face it that's not the fun in propper road riding. Studded tyres is not an option...

Re: Gloves for cycling

Hi I don't suffer with cold hands and I don't like waterproof gloves because I find that they don't "breathe" and I end up with the fingers full of sweat. My preference is windproof gloves and there are some suggestions here...I've got the Carnac Ultimate, but the Ultimate Windblock might ...

Re: Mech hanger availability? Time to stock up?

Hi Take the hanger off, make a pattern, keep the pattern safe. If the worst happens try someone like this https://www.lasermaster.co.uk/metal-laser-cutting I would also like to know what you're doing; I've never had to replace a hanger although I have straightened the odd one Regards tim-b

Re: Why does ‘cyclist wearing dark clothing' exist as a contributory factor in KSIs

Hi
MickF and OldJohnW +1
It's not about victim-blaming, it's about having the confidence to cycle safely. The more people that cycle the more the balance moves, and if it takes hi-viz to achieve that...

Re: Why does ‘cyclist wearing dark clothing' exist as a contributory factor in KSIs

Hi Most recent example is a new conurbation in NL where there are ZERO parking spaces for motors It's not as simple as painted, e.g. people have to be able to get to jobs on time while dropping off and collecting partners, children, etc. and their car may be the only practicable way to do that. It m...

Re: Alu post stuck in alu frame

Hi I'd be as wary of using ammonia as you are, and I agree that you have to break the bond/expansion of the oxidisation. You could try to use a hacksaw blade and carefully cut along the inside length of the seatpost. For ease, cutting relies on the shortest cut so try to determine how much is in the...

Re: What Vintage Raleigh Bike Model is this?

Hi
I doubt that the rear wheel is standard and it's possibly the single most valuable component. The rest is nothing special IMHO

Re: Corrosion to BB on 2011 carbon Supersix

Hi Is this a carbon fibre (CF) frame? You can get a destructive galvanic corrosion where aluminium components are in contact with CF. I can't see it in your photo, but have a close look at the joint line between the two materials on both sides. Manufacturers are well aware of this and use a "ne...

Re: Why wear black?

Hi We might take away the message from that that it's okay to wear hi-viz, and it's okay not to. Same for helmets. And that is the state of the actual evidence The BBC are around 1:3 on the hi-viz, but more emphatic on helmets where they're visible in the tandem ident BBC Cyclist Ident link BBC Tand...

Re: Roof racks

Hi
I'd try a specialist company, e.g. https://www.roofbox.co.uk/roof-bars/. I think that you probably want roof bars, as opposed to a roof rack, but companies like these should be able to sort something out for you

Re: Fork crown race fitting

Hi
On a 1 1/8 steerer (which is a legacy diameter), the SHIS standard for the fork crown seat is nominally 30mm. The actual dimension should be 30.015mm to 30.075mm (https://blue.canecreek.com/resources/products/headsets/PDFs/canecreek-shis-poster.pdf)

Hi The 622 and the 25C is the important bit, the rest is manufacturing-speak ETRTO recommend a 42mm minimum width with 25C rims, although individuals report that they have gone narrower You also need to decide what's important: Rolling resistance, on-road grip, off-road grip, puncture-resistance, co...
