Has anyone run 27.5 front and rear on a big dog?
Just wondering as I took the kids to Cannings the other day and having previously gone on a 26 and 27.5 I found the big dog a bit cumbersome on Blue Steel (or death by berms!).
Thought maybe having a pair of smaller wheels to chuck on would give me a bit of variation?
Ran 27.5 on rear with plus tyre. Worked great. Slacked the head angle. 175mm cranks as well. Back on 29 at the moment but wheel is in shed should I need a replacement. Not recommended by designer but fun experiment.
I think @brant might have done this at one point.
Bottom bracket would be a bit low for me - I primarily ride in the Peaks - but may well be fine at a trail centre.
Slacked the head angle
And “slacked” the seat angle, shortens the reach. And of course you can steepen the seat angle by moving the saddle forward, but then the reach to the bars gets even shorter.
If you’re having trouble riding a 29er with children at a bike park then maybe a skills course or a bike set up with someone experienced?
If you just want to dick about with bike set up for the lols then crack on.
Just dicking about to be honest, I'm still trying to convince myself I don't need to build a trail centre/jump rig up as I've just cleared out all the bikes I own and never ride!
Lol.
On that particular 2 minutes of trail my strava times are certainly slower the longer the bike is. Pb set on the old 26 hardtail equalled only once on a 29er ht with Xc geometry.
Everywhere else the bigger wheels and longer wheelbase make things much better.
I wouldn’t be ruining 99% of my riding to make 1% easier!
I would think that off-road the lower bb would offset any gains from increased agility of the small wheels
29er wheels are fine. Doesn't seem to slow the DH boys down!
