Re: Rusty bolts and aluminium fittings...

Hi If the bolt is stainless steel that is, by the way, very bad for corrosion of the alloy, because chrome and aluminium are a long way apart in the electrochemical series The electrochemical series is an indicator of risk and needs to be looked at in specific situations, which interests me on a pra...

Re: Worn tyres on brand new bike

Hi The rims appear clean and unscratched so no major braking/extended test rides The tyres have their moulding flash on the tread so not too many miles there, a rear particularly will lose that within maybe 100 miles If the bike was heavily discounted then I suspect that there's no more to come, alt...

Re: Derailleur Hanger alignment tool ?

Hi IMHO few derailleur hangers are always aligned accurately because the wheel can vary relative to the chain stays and seat stays each time that its fitted Alignment tools often have a pointer that slides along the handle, and that needs moving for 12, 3, 6 and 9 rim measurements because the hanger...

Hi
Stainless bolt? More corrosion-resistant both in contact with alu and in general

Re: Carrera cross fuse : OK to loosen handlebar LCD unit ?

Hi Two thoughts occur: Do you need to turn the bike upside down? If you have a garage suspend the bike from the rafters at a comfortable height static loops will do (link) Not everyone has a garage, or you may be at the roadside. A couple of polystyrene blocks weigh very little and can be put under ...

Re: Uphill, downhill, both, neither?

Hi
Ambivalent about either uphill or downhill. Uphill is needed (by me :) ) to show that I've worked, UK roads are too poorly surfaced/narrow/bendy for anything above 40mph (downhill :) )

Re: Suggestion for wall/floor anchor?

Hi Does this mean digging a really big hole and burying said anchor? You could do and save a fiver for the bucket, or leave it on the surface. A tapered bucket attached closely to a lock won't roll too well; you can't leave projections to stop rolling because that makes it easier to carry. It's not ...

Re: Suggestion for wall/floor anchor?

Hi Fill a bucket/car tyre (the larger the better) with concrete and partially embed a length of hardened chain/old D lock inside. A litre of concrete is 2.4kg and a 40L soft gardeners bucket is under a fiver, which will give you a 96kg anchor Brick is quite soft and is only as good as its fixings Re...

Re: Review of Highways Act 1835

Hi Can anyone tell me why you can't use an electric scooter on the road? This was a problem during the late 1990s with the proliferation of the Go-Ped in the UK. Some had a petrol engine and some were electric-powered. Lord Justice Pill and Mr Justice Bell closed a loophole through the case of R v S...

Re: Advice for corroded aluminium frame head tube

Hi Ally corrosion begins immediately it's exposed to the environment. To a certain extent the corrosion will protect against further corrosion, but yours has gone beyond that happy place It depends what that frame means to you, but IMHO yours will need lots of work if you're going to keep it in look...

Re: Continental tyre degrading

Hi The only issue that I've had with Conti cycle tyres was a thread in the narrow rim protection layer of fabric unravelling on a Gatorskin. Cambrian dealt with that very efficiently, although I think that you get referred to the retailer, which is where your contract is Any problems with a front ty...
