New rear wheel advise, please
I'm considering a rear wheel replacement for a Dawes Super Galaxy
The current wheel has 40 spokes has a 135mm spacing with a drum brake, 6speed freewheel and a 700c rim.
I've replaced the rim tape and inspected the inner rim, but it's still giving me persistant flats/punctures. They're all happening on the rim side of the inner-tube - nothing is penetrating the new schwalbe marathons.
It may be time to replace the wheel. Would you agree?
I don't think I'm going to get a wheel that'll give me the drum brake, but perhaps I don't need it? The max descents I'm doing is 1km with a 5%. Or maybe 500m with 12%. And I'm being conservative there - in reality they're a lot less.
So perhaps I don't need the drum?
Also, do I need 40 spokes?
Hybrid rear wheels (which I think would fit?) are 135 OLN - would a double wall wheel of this type be suitable?
