Re: Bicycle Brinkmanship....?

There is doing things as they should be done (hence the mechanics unrepeatable language), and there are doing things that while unconventional/not "proper", do work (after a fashion). Your bike falls into the latter - and better to do such things only on your own bike..... As for criteria,...

Re: Centre pull cable pinch bolt slippage, with pics

The M6 bolt (10mm spanner nuts) is designed for normal (and none Weinmann) canti yokes which are flat plate where the bolt head sits - thus the head can clamp down onto the cable. The correct M5 bolt (8mm spanner nuts) head I think slots in the groove, allowing the bolt to clamp move further in and ...

Re: Microshift vs Shimano compatibility

Thanks for the advice, in the end Decathlon got him a replacement LH lever from France (which seemed their preferred option over getting one from the Croyden store!) and fitted in just in time for him to go the Isle of Wight for the weekend. Fortunately they fitted it and adjusted it well, so all wo...

Re: loctite stud lock 270

There is a huge number of Loctit products. I looked through a catalogue at out local bearing supplier a few years back (looking for the right one for securing the rear axle bearings on an old 8Freight, or it might have been for a lower headset cup in a steel frame). To give you a idea, some were for...

Re: Bolt types and sizes

My hunch is the top bolt is for bolting an inner chain ring to an older Shimano triple crank - the tread length (to me) suggests the older design where there is a separate spacer between the inner chain ring and the crank. On later models the crank forging had more protruding mounting points for the...

Re: Ammaco CS250

Most Ammacos are pretty poor (I repair some at work...), with most having very poor quality cup and cone BB (crank) bearings. The CS 250 is what I would call reasonable/passable as it is I would say the best(ish) model they do. The good news is the CS 250 has an adjustable cartridge BB bearing which...

Re: First time commuting on a bike, I have the option to exchange but would like advice on specs please

Lithium 2 is 7 speed cassette, stated ratio is 12 - 32t. But as a general point, most 7 speed bikes are screw on freewheel. To add other options, I'd go for hub gears/single speed (depending on hills), as more weather resistant, cheaper to replace chain/cog(s) when worn out. Some people in the past ...

Microshift vs Shimano compatibility

A friend has had his LH Microshift STI lever/brifter fail. Lots of LH double levers about, triples harder to come by (UK distributor out of stock until September). If he subs a Shimano STI lever (subject to brake cable pull etc) using the original microshift front gear, will it work?, or does he hav...

Re: saddle fore aft position KOPS

As I understand it, it is what I would call the hinge of the knee/sticky out bit over the pedal axle (crank horizontal/forward). I recall somewhere seeing a plumb line from the front of the knee cap over the pedal spindle which I take as wrong. If I used the front of the knee cap over axle version, ...

Re: Uber Licence plates - Can you get them?

Thanks for the https://vehicleenquiry.service.gov.uk/ViewVehicle link, I was aware of such a thing but never looked to find it. I thought I'd give it a try. I don't have a car, so looked out of the window for a number plate, only 1 neighbours car visible, so I put that in. Oh dear, it's un taxed!! A...

Re: Cyclist dismount?

In Oxfordshire we have managed to get them to put up signs "Narrow lanes do not overtake cyclists". The occasions that dismount signs are used it is with contractors who should have known what the County expected of them. I think the thing that swung it was when the High St was rebuilt - s...

Re: Raleigh Centros Headset Adjustment ?

To be fair to Brucey, I don't think he's particularly having a go at you personally. I used to teach cycle maintenance courses, and wrote detailed instructions on how to do various adjustments. People's mechanical skills vary enormously. Some people I've taught have a vague idea how to do something,...

Re: Raleigh Centros Headset Adjustment ?

If your old bikes had a "bolt down the centre", they would be the older style quill stem/threaded headset, Yours looks more like an A head threadless headset design - this should have a (smaller) bolt going a (short distance only) down the centre (used to adjust the bearings) - but yours d...
