I bought a ‘Halfords Special’ earlier this year.
I’ve had more than my money’s worth of fun with it since.
As these are built to a price (and it is a bargain as it stands) compromises were made:
- The headset bearings lasted about three months in the wetness of the Lake District. I replaced the factory-fit “thing” with a no-name clone of the Hope S.H.I.S. ZS44/28.6 (upper) and ZS44/30 (lower). This gives you cartridge bearings for your 1 1/8″ steerer. Some astute observers suggested that you might use a EC44/40 at the lower, to give you compatibility with tapered steerer tubes. You might want to replace the forks in the future. The factory fitted bearings had no seals installed, so it was not much of a surprise they failed soon.
- The bottom bracket failed after about 6 months. What was fitted was a 100mm shell, with a 154.5mm square taper spindle. Made by some cheap manufacturer with bearings made of cheese. This is where it gets weird. Halfords have told me their ‘technical records’ indicate the spindle length is 164mm. I know that one Wazoo left the factory with a 154.5mm spindle…
Finding a replacement proved to be tricky, and the best that myself and my local LBS could find was an On-One 100x148mm BB. This fits, does not destroy the chain line, nor causes any mechanical issues. It looks like a superior replacement, with doubled-up bearings at each end of the spindle. [ I reserve the right to revise my assessment of the BB at the end of its life ]
Halfords did suggest I order part number 153878 “BBS Wazoo 2015 BB” for the sum of £16. I have done that purely for the curiosity value.
I wanted to put these technical bits in to the public domain, in case they help other bikers dabbling with fat bikes. The nearest whole bike which can compete with the Wazoo costs around £1000, so it is a compelling choice for an alternative mountain bike.
(7/10/2016) The Halfords part number will provide you with a 154.5mm spindle BB, for a 100mm BB shell. I think I will continue buying the On-One part, on the basis that it is more likely to survive being wet once or twice.
