So out of that lot, i’ve ridden:
26 El guapo (owned one, good bike but too small for me in a large. Makes a better DH-y bike than XC-y bike IMO)
29 Horsethief (for me, better in every way than the EG, though a lot of that is sizing. Bigger bikes are better for DH, including tight and twisty if they fit you better!)
From these two:
” big Scottish hills days out,
Would prefer the HT. Long TT means you can get a good XC riding position yet with short stem etc. for good DH handling.
Assuming you mean the proper DH tracks used in the SDA – the EG would be better for them, purely cos you can get burlier wheels and tyres. Nothing like a proper DH UST high roller for 29er yet. Closed you get is more like a singleply/exo. I’d ride the ‘thief down them though, but you really just want more travel.
some Enduros and maybe the Megavalanche
TBH either would be fine for these. The mega is long enough that it’s swings and roundabouts in terms of what the bike’s good at where. And how well you do is less about your bike, and all about your gridding in the qualifier (you want to be near the front so you can qualify for the main race). So that’s just all about having other race results. If you’re just there to ride rather than race, as it were, then pretty much any bike would be fine, though some sort of full sus preferrable, and tough tyres.
The one i’ve not ridden, but I know folk that have (many times). From what they say, you want something that can climb ok, as it’s a lot of long days on the bike. For me, the HT would suit better. It’s also better at “covering rough ground quickly” and a bit more sure-footed than the EG.
