Bumping this up - hate 29s so would have to go 27.5 on a Levo, also dislike Plus or anything over 2.5 which leaves me on 2.4/2.5 tyres on a 27.5 rim.
= BB drop circa 18/19/20mm.
I believe the flip chip might get me 5mm back but it's still a fair old drop.
Anyone been there?
Anyone (who's bored or can be bothered ) that has a regular 150mm travel 2019 Levo and a spare pair of 27.5 wheels with regular tyres (say 2.4 to 2.6) NOT PLUS could you possibly be ultra kind and measure your BB height centre to floor with the 29er wheels and then with the 27.5s popped in. And with the 29 front/27.5 rear too! I know it will differ here and there with tyre profiles etc but a ballpark difference would be really helpful.
I'd be eternally grateful.
I was saying plus cos most ebikes tend to run plus size tyres, to me anything bigger than 2.4/2.5 I call plus
i tried the front 29er and it was not of my liking. did a few laps and just couldnt get used to it.
im spoiled by the 6 fattie. with the 6fattie you can just barrel through the roots/rocks with no regards.. the 29'er is unforgiving so you have to choose lines carefully and id venture to say its a bit more tedious.
Great stuff Dave, thanks for doing that - that's interesting and a result - Specz give the 2019 with the factory 2.6's as 5mm higher (347mm) and would have thought the Butchers might be less tall than the MM?
But your test with the 27.5 on the back checks out pretty close with the post I made earlier on a 27.5mm shorter bike:
Raising the front.......by 19mm makes the BB difference 9mm....
But this bike is 100mm shorter wheelbase than the long Levo...so the difference would be slightly less.
Flip the chip to get back 5mm and 1/2 degree and then to sum up:
Swapping like for like tyres (regular 2.4 to 2.6) on a 2019 Levo then a 29er front, 27.5 rear set up will be less than 1/2 degree slacker and less than 5mm BB difference in high chip position. However, going narrow rear (2.4), wider front (2.6) would make this difference a little more
So, if you flip the chip now you should be virtually the same with only a couple of mm difference - great news.
I was watching Neil's video on GMBN yesterday with the 27.5 vs 29er test and he did mention that running a 2.4 on the 29er wheel against a 2.6 on the 27.5 wheel made a 20mm diameter difference so 10mm off the BB height. But he's swapping both ends.
Summing up again (!) if for whatever reason one wanted to try a 79er set up (I do ) then it's no big deal in terms of BB height change - stick a 2.4 on the 29er up front, a 2.6 on the 27.5 out back, flip the chip and you're only going to lose maybe 5mm and 1/2 deg on the angles.
Even running 27.5 both ends on 2.6s would be fine too.
Plan: buy a fully sorted Levo just this year optimized for 29er wheels and turn into a frankenbike via the power of maths and a spreadsheet... gonna go bang my head against the wall
Come on, hardly a 'frankenbike' by any stretch of the imagination is it? Really?!
Bikes are very adaptable and not everyone wants the same or maybe some want to try something (ever so slightly) different. Discussing it on here is to see if it would be viable. Riding it will tell the truth. But a few mm's here or 1/2 degree there on any dimension really will not upset the boys round the geometry table at Morgan Hills (or Cham or wherever) I'm sure...
