I have accidentally discovered the beautiful simplicity of the innards of a Hope Pro II rear hub this evening.
To explain, I snatched the bike out of the shed to pop some different tyres on for the anticipated snow at the weekend, but spotted a broken spoke. Damn it. And it always has to be the drive side doesn't it?
Cassette lockring nearly defeated me, only a dousing in WD40 with the disc rotor in a freezer bag and some brute force shifted it. Great, just got to whip the cassette off and we're in business.
Disaster strikes - the cassette has chewed into the splines of the freehub body and won't budge. A lot of levering and cursing later the end cap pops off and so does the freehub - cassette still attached. Now I can push on the back of the cassette directly I can get it off.
Remember, this all started as a broken spoke!
Now I am out of my depth. Or so I think. I panic and start looking for the Merlin and Hope email adresses. Just to salve my conscience a bit, I think "I'll clean all the bits up for them so at least I don't look a total prat".
On starting to clean it up, the magic is revealed. Simple and easily separated components and a great big ratchet in the hub. A bit like comparing an AK47 to a SA80 - simplicity and ease of service wins through in the end.
Obviously there are problems here - I need a new freehub body and am a bit annoyed at how soft the metal was. One of the leaf spring behind one of the four pawls has also sheared off - god knows how long it's been running on three contacts.
However, I am going to slap it back together when I've replaced the spoke - it will be no more damaged after one more ride on Saturday, I can then get it repaired at my leisure and not miss out on any riding.
Loads of bike component irritate me with their unnecessary complications or deliberate non-compatibility. Why use hex bolts when an allen bolt is just as good? What difference does ten splines on a BB axle make versus eight (other than tieing me to a specific manufacturer)?
More things like Hope Hubs please!
P.S. If this makes me sad, I'm happy to be sad - there was a load of old crap on the telly tonight anyway.
