Had an absolute blast to work this morning on the Fire Mountain. Average of 18.3mph over 7.4 miles, max speed of 29.8, and 29 Strava trophies including a PB on all but three sections. Not bad considering it’s not an out-and-out speed machine. That was with a 20mph tailwind (hehe), and I think I’ll be making up for it on the way home – 40mph+ headwind from 18:00! Ouch. Pretty good reason to leave work on time, methinks!

I realised pretty soon after starting this job, that the proper tools are needed to remove the headset cups.. same for the crown race.
So I resigned myself to not being able to remove the cups, But thought I’d have a look at whether the individual parts from the new and old headsets would play well together.
For the crown race, I kept the old one in place after verifying the new bearings would fit into the lower cup, and used a rubber seal from the new one.
For the top cup, again I found that the bearing race fitted perfectly, so used that along with the top cap, plastic wedge etc from the old headset. I packed both cups with lithium grease after cleaning the cups out.
It all fitted together very well, and I adjusted the play out of it to prevent notchiness in the steering.
The proof is in the pudding, and I commuted on it for the first time today. I’d also cut through the lock keeping the old saddle in place, so I could fit my old Selle Royale Respiro that I had on the Dawg Primo.
The bike is very close to being nailed now.. just the seat height and angle to tweak.
I even managed 14 Strava trophies, including four PBs over the 7.4 mile distance, result!
The last part (hopefully) needed for the Fire Mountain is a new headset. The other one has various disintegrated seals, very old grease, and is generally looking very sorry for itself.
Bought a new one from Halfords – a £15.99 special – but I have no tools to fit it. I’d seen a YouTube video by RJ The Bike Guy where he used a ghetto headset press, and realised the things are for sale, ready made, on EBay. These comprise a threaded rod with large washers, with nuts at each end that are turned with a spanner, to push each part of the headset (individually) onto the frame.
So I bought one of those at £7, due for delivery tomorrow.
In terms of the crown race, I have some plastic pipe, also used by RJ, to push the race on to the fork, and will remove the old one using a screwdriver.
