The Mk5 is very similar geo to Mk4, just shorter offset forks for b+ rather than 29+.
Basically what I run, MK4 with speedball forks to allow b+ to work better. #trendsetter 😎
I've got a set of boost 29er wheels (on Stan's flow MK4 rims), currently on 2.2 Mezcals, but can fit something more burly on there if needed, and of course I can 'boostify' the rear from the mk4. How do I boost the front wheel? Can't see a Hope kit for that.
Haven't got anything lined up for 27.5, but may want to go there as a + option.
The Mk5 is very similar geo to Mk4, just shorter offset forks for b+ rather than 29+. Suspect it will be a bit more lively and less confident on steeps because of it, but maybe better for most?
Yeah, I think this will be a bit more where I want to be.
Reduced offset on b+ should keep the handling similar.
@Paul-B that's quite the running total!
Mines set up B+ at the moment, with some tasty tanwall Maxxis Rekon+ front and rear. I think I'll keep these on for the summer and change over to some 'standard' 29ers for the winter to cut through the mud a bit better.
I've never ridden 29er though so haven't got much to compare against!

Shorter offset on sus forks adds stability for the gnarlier stuff, especially at higher speed, but it’s only a small change, less than 10mm. Makes them more reluctant to start a turn but then better at carving an arc.
A 23mm reduction is much more drastic so I don’t know if you’d actually notice the shorter front centre on steep stuff (I don’t think you do on short offset suspension forks). It’ll certainly be calmer when you’re going fast.
I guess the 80mm offset was to stop a massive 29+ wheel and tyre being too slow steering, especially as on a rigid bike it’s not as easy to monster truck in straight lines.
Nobody ever believes me when I tell them how good my Mk4 is, they just look at me funny
Same with the Dirtbomb. It’s way more capable than I thought it would be and very fast too. Think the honeymoon period is over and I still love it. I briefly had a Speedball and the Dirtbomb, for me, is even better.
@bonzodog Just use the generic boost converters. They come with a pair of spacers for either side of the axle and a disc spacer.
However a bit annoying if you need to remove the wheels regularly.

I'll give that a try, cheap enough if they don't work out.
I am surprised that Hope do a dedicated kit for the rear, but haven't bothered with the front. Odd.
Ah man this thread really doesn help! I was very close to outting my name down for a MK5! As could swap my parts all over, A MK5 still be ok with 29x3" front thought wouldnt it?

Yes, according to the Stooge bumf...
But the official wheel/tyre sizes for this are 29×3 front/29×2.5-2.6 rear (its that old BMX thing rearing its head again), or 27.5 x 3.00 front n rear. In reality it’ll descend and rip just as well as the MK4 but the front will feel a little poppier.
Oh yeah its designed for 29x3
Enjoying the Dirtbomb - have just squeezed 29*3 in at the back!
Well, as my stupidity has rendered me Stoogeless and I fancy a day off from my single speed, I'm gonna go for a good long afternoon blast on this after I've yammed my cheese & onion sarnies.

Used the front wheel from my (ex) Stooge 🙁 and so now on a Minion DHF.
It steam rollers along pretty well but I'm not so sure it has any place in a thread with a 'proper' trail bikes title.
@addy6402 that's absolutely gorgeous! So pretty I'd be reticent to get it muddy!
Bonz, it'll all be well in the world when your MK5 arrives! The MK4 is coming with me on the family 'holiday' up to near Cannock Chase next week so I'm looking forward to trying it there.
I do love my Dirtbomb. Swapped the bars to Scrambler, stem to a 50mm Hope and all spacers are now silver.
@boxwithawindow - they are Duroc 40 (36 internal). The wheels were from Triton.
@abingham - thanks! It has been christened with mud, cleans up well too...
Oh, and if anyone wants some 29+ boost wheels I have some Mulefut 50SL on DT DSwiss 350's in classifieds...!
