from what ive heard there using very little if any of the grizedale northface trails etc

its supposed to be largely fire road according to the organisers id just pack the hard tail

im not doing it but a few mates are , i finish uni on wednesday and will still be to paraletic to drive at that point

36 and mtn cassette would be fine if your in a team im using a triple for my next solo at mayhem

You dont need a full sus for the north face trail anyway, a hardtail is best for grizedale.

Whats the Wildboar race anyway?

for 24 hour racing id take my heckler or any other sub 4 inch fs bike thats reasonably light over a hardtail

unless someone supplied me with a 29er hardtail !

my mates doing it on a 29 hardtail solo 24hours with singlespeed 32-19 to give you some idea.

you can ride up owt on 32:19 .......

i ride 32:18 on my 29er SS for 10 hour races

if i was to use my SS for a 24 id be using a 32:19 or possibly 20 just to save my legs for later stages

its 32:17 on 26"
