I intend to organise a CycleChat offroad forum ride early in the spring but my ancient MTB has been out of action since before the pandemic so it is well past time for me to sort it out!
One of the bike's old Hope disk brakes had died. I never really liked those brakes anyway because they use a sealed hydraulic system which overheats on long descents with lots of braking so I decided to replace rather than repair. I had been given a pair of SLX disk brakes which I am going to replace the old brakes with. I had already put the front brake on and that works really well. The thing that stopped me doing the rear brake was having to faff about with the hydraulics of both the rear Hope (to get it off) and the rear SLX to feed the pipe through the frame mounts (the brake had been taken off another bike with its hose intact and connected). I decided to do a temporary bodge job for now and fit it properly later if that ends up bothering me...
I cut the hose of the Hope to get that off, and fitted the SLX
without feeding the hose through the frame mounts, instead cable-tying it to them. I was all set to bolt the calliper on when I discovered that the MTB has the old IS mounts and the SLX calliper has the newer incompatible type of mount. That is what we call an afternoon fettling show stopper!
I have now ordered a mount adapter which I will use to fit the brake next week.
I wouldn't be surprised if the transmission needs TLC but I haven't looked at that yet. I will check it tomorrow and order any parts that I need.
I have a replacement saddle and new bar grips to fit.
The rear tyre is good. The front tyre has plenty of tread left on it, but it is over 15 years old and the rubber is showing signs of perishing so I will replace that. I will get the biggest tyre I can this time. The fork only has 80 mm of travel so a bit more give in the tyre would be handy.
Speaking of that fork... Considering that it is 22 years old and it has never been serviced, it still seems to be working pretty well, but it needs more air pressure in it. I don't have a shock pump but I know someone who has a suitable one so I will ride over to see him once the other jobs have been completed.
I'll report on progress over the next week or so, and finish planning my forum ride route. It won't include any of the gnarlier downhills round here because I don't want to have to scrape myself or any other CycleChat member off our local millstone grit boulders, or have to scramble 50 metres down a 30% slope to rescue them from some dark, dank ravine!
