Way back in the 1960s when I got my first serious bike, the wheels had a chrome finish which I used to polish with DuraGlit, or something similar. I would keep the chain and gears well oiled with 3-in-1 oil, and would oil the wheel bearings with same.

However, my latest Pro-Bike "Enterprise", which I bought this month, has no chrome and is made (I believe) of aluminium alloy. The chain and gears do not need oil, the salesman told me. There is a light coating of grease, but it's basically a dry mechanism. The chain itself is apparently made of some kind of aluminium alloy. However, I was supplied with a spray can of PT85 - rather like WD40 and contains PTFE. It's water repellent.

On Thursday, I went for a ride by the River Thames, using the towpath. After all the rain we've had, it was extremely muddy, and the bike got filthy. So did I! I cleaned the bike using a pressure washer which was ideal for blasting away all the mud, which was even in the chain and gears. Afterwards I sprayed PT85 on the chain and gears, and repeated this treatment the following day before my next ride.

Am I on the right track with this form of maintenance? I was worried that the pressure washer would wash off what little grease is on the chain and gears. That's why I used the PT85.

I tend to find a pressure too powerful for bicycle. I use a gentler hosing down if really mucky. Usually - it's a bucket of water, a bottle brush, a toothbrush, sponge, washing up brush and a chamois leather. I use a bike wash or even washing up liquid - and a water soluble degreaser I use the brushes to gently remove the mud from the awkward areas and then rinse and dry off with the chamois. I even use a bike polish to restore to pristine gleams too. :lol:

After this I lube it down - with a dry lubricant - even spray after ride in the rain - and nothing wrong with checking the grease on the bearings either. I spray up the brake levers, pivots, cantilevers, front mech, chains, sprockets, rear mech, jockey wheels and V-brake but you wipe off excess as it attracts dirt. :wink: You only need a light squirt and use judgement as to frequency for some parts.
