Diary of an Amateur Wheel Builder

Is it as difficult & expensive to build bicycle wheels as it's often made out to be? Let's find out... my goal is to build some LBS-quality wheels at or below mail order prices!

Hubba Hubba!

Wheel hubs fascinate me. With the right hub it’s possible to get it running so sweetly that it’s practically frictionless and won’t need servicing for years, yet get something the teensiest bit dirty or out of line and it turns into very centre of cycling hell. There actually aren’t that many to choose from. From Shimano, only Deore XT are really an option for me because Deore can have rough bearings from new, are badly sealed and are weak (I seem to be able to break the freehubs at will). Deore LX hubs are scarce and I’ve no idea whether they are nearer to Deore or XT in terms of quality, and XTR are daft money.

Hope only really offer the XC or the new Pro II, both of which cost plenty and use cartridge bearings which I dislike. Cartridge bearings just don’t spin as effortlessly as cup-and-cone bearings and maintenance involves a hammer, a bin and expensive new bearings which you then hit with said hammer!?! I’ve used both Hope Mono & XC and Shimano Deore XT hubs over the past few years and it’s the XTs that have performed the best. Then there’s the cost - £80 for a new Hope XC rear hub, versus £27.50 for the equivalent Shimano Deore XT which also comes with an excellent quick release skewer. Knock the £7.50 off for the cost of the skewer and the Hope hub works out four times as expensive – overpriced and over-rated.

So it looks like Shimano Deore XT, in which case the choice is between the old 6 bolt IS hubs or the new Centrelock versions. Despite it being part of Shimano’s detestable grand plan to build obsolescence into all cycling components, Centrelock rotors make a great deal of sense. Trouble is, they’re new which means little prospect of discounts, and for compatibility reasons (i.e. all my rotors are 6-bolt!) I probably want to avoid them.

Just to point out Mike, that soon enough, you may be able to buy some adaptors to allow you to run a 6 bolt rotor on a Centrelock hub. WTB and DT Centre Lock to 6 bolt adaptor are already making them, IIRC. As they are "compatible" with Shimano's centrelock fitting, logic would dictate that they would fit a Shimano hub (as well as a DT)... in theory.

Oh, and i totally agree about your preference of cup and cone over cartridge. Cup and cone is much nicer running and easier to look after. All it takes is a little maintenance periodically, and all will stay sweet =0>

I think the concept of Centrelock rotors is an excellent one and all other things being equal they're what I'd go for, no doubt about it. However as they're still fairly new they're still relatively expensive for the amateur wheel builder, and anyway all my current disc brakes use 6-bolt IS rotors. I know of the DT converter (hadn't heared of the WTB version tho') but at £20 per wheel it's not exactly a bargain even though it is a neat little gadget!
