Hi all,
I had a friend come and help me bleed the brakes on my BT7 last week, which I have owned for 28 years. The 72 spoke chrome wires have been on for about 27 years (i bought them in Houston where I was working at the time, and now live back in the UK).
My friend asked me when did I last check the splines and I said never (despite being aware of the issue from Norman Knocks book). On examination three of the four hubs showed worn splines (sharp knife edge at the top of the spline). One had only a slight movement, which the other two had about 1/4" movement on the outside of the tyre. As expected the wheel centers are also worn. Rather oddly the left rear was OK. The hub on this wheel had clearly been replaced by a previous owner as it did not match the other three hubs. The spare was fine as its never been used.
I now have three worn hubs and three worm wheels with a pair of decent wheels.
My options are:-
1) Buy four new wire wheels (Ā£1080) and change out all the hubs,
2) Get three wheels repaired (Ā£900) at about the same cost of three new ones (Ā£810) and change out the hubs. This will leave me with a full set of original wheels.
3) Buy two new wire wheels (Ā£540) and pair them on the front and use the two good originals on the rear (all with new hubs).
Is there a safety issue with the cheapest option, using two different sets of wires on the front and rear? What does everyone think?
Thanks Phil
