In the end it took me about 1.5 hours, not including any general bike-cleaning time, but hey it was my first time installing these parts. I installed a new rear cassette, chain with Wippermann Connex joiner link, and middle and large front chain rings.
It wasn't exactly problem-free. I couldn't remove the old cassette using the Parktools FR-5 cassette lockring tool, because (a) it doesn't fit perfectly (has about 1mm of movement) and (b) lacks a stabilising pin in the middle. Every time I applied pressure on the adjustable wrench, the damned lockring tool fell off! In desperation, I took the wheel, with my chain whip, adjustable wrench and the FR-5, to Le Tour Cycles in Ringwood, and (naturally) Anthony had the lockring loosened (using my tools) in a few seconds
. However, while I was there, I bought an IceToolz lockring remover that fits perfectly and has a stabilising pin, so it should be a lot easier to use.
Putting the chainrings and chain on was easy enough, as was installing the new cassette, although the middle chainring only just
comes off / goes on over the crank. So I didn't have to do anything messier, like removing the crank. I'll have to find a wider-bladed screwdriver for the inside bolt securing the chainrings, though. I had to improvise by using the edge of a metal ruler to hold the inside bolt while I tightened the outer Allen bolt, because 3 of the 5 bolts wouldn't tighten otherwise. I also greased the Allen bolts before putting them back on, and also greased the quick-release skewer before putting that back on, and used a pipe-cleaner to remove some of the gunk from inside the quick-release hole in the rear hub.
I took the bike for a quick test ride, which included riding it up hill in high gear, and noticed no chain slipping, so all seems OK.
I'm a very happy man, who's now slightly less dependent on bike store mechanics than he used to be
Tomorrow, I'll take care of the rear tyre and rim tape; that will be nothing I haven't done several times before. I'll also be placing an order online with Chain Reaction Cycles sometime soon, for various bike-related items, and I'll be including in that a replacement middle and large front chain ring, and 2 replacement chains, because I'll be trying out Roshea's 3-Step Chain & Cassette Replacement Program
In other words, use 1st chain for 2500km, then 2nd, then 3rd, then 1st, 2nd, and 3rd again, by which time all 3 chains and the cassette get replaced, so this sees 15000km of use for the cassette and 5000km of use per chain.
As for the chainrings I just installed: I managed to find a new Shimano Sora 39T chainring (BCD=130mm), and a 2nd-hand Shimano Sora 50T chainring (BCD=130mm). The 2nd-hand one has clearly had use, but it wasn't anywhere near as worn as the one I just replaced, so it should be OK for a while.
