I'm curious if 32" advantages will be course dependent this year (i.e. better for courses where momentum can be carried for longer periods) or if the weight penalty for spinning up the larger wheel is not a large enough factor to prevent it from outperforming 29" for every course. We'll just have to see how the results are this year...

As I've said previously, if these two tests are showing 2-6% performance gains from going to 32" wheels, those with them this season will have a MASSIVE advantage. XC World Cups are won/lost by seconds these days. <1min sometimes encompasses the top 15 riders. 1 minute over the course of an 80-minute race is 1.25%. Marginal gains (aero parts, lighter lube in hubs) that these teams work for net racers WELL under 1% advantage. And these wheels will likely be netting riders 2-6% gains. Even if in the real work that that number is as low as 2%, that will...

I agree with all of this, and the current situation just has me sitting on the fence waiting for Bosch to respond, rather than jumping on an Avinox that may or may not prove to be riskier from a service perspective depending on how long term warranty and parts availability plays out.

The public has spoken, they prefer skinny downtubes over better handling. Even though many have documented that lowering the weight in this place is very noticeable and in a good way. My personal opinion is that Bosch should offer a skinny 800 (or more) battery to match what Avinox is doing as an option for the manufacturers. They can still offer the fat 800 if they prefer. I'm susceptible as well to the fashion statement. I wanted a 600w battery and I didn't want my bike to look pregnant and obviously be an e-bike. If the LTe had a narrow...

Interesting back to back testing between 29'' and 32'' wheels hard-tails on XC loop from French magazine Vojo. the result shows faster times for the 32'' wheels in every loop parts ranging from almost 2% to almost 5% in the different sections (flat, uphill and downhill). https://www.vojomag.com/notre-vtt-32-pouces-face-au-chrono-vraiment-plu…

Unfortunately that is not correct. RC, FC, and WB are all horizontal measurements. CSL is the point to point measurement from center of BB to rear axle, and there's no name (or need) for the equivalent version at the front.

Weight is probably the main reason on this bike. And personally I think it makes sense, a lot of short travel bike coming out now with frames weighing as much or more than 150mm bikes like Stumpjumper

It's actually dumber than that. To make the numbers work: "Front center" is measured from BB to front axle as you've depicted, but "rear center" is just used interchangeably with "chainstay length" and is the horizontal measurement from BB to rear axle.

Great question. You'd think so, but no. Because the BB sits below the axles, and because FC and RC are measured from the center of the hub axle to the center of the BB, the FC and RC don't form a straight line. They form a slight "V" as they both dip down to the BB. Then you consult Pythagorus to get the exact difference in length. [Editor's note: This is wrong. See @kperras post below for full and correct explanation]

That's a great call out, and I 100% agree that handling is much more important than a good looking frame. I should have specified that in my post, but until battery tech becomes more power dense I don't think it'll be possible to meet all of this criteria at the same time, but 🤞

Slim downtube also means that the battery has to be longer which raises the center of gravity which is bad for handling. Yeah, a nice looking bike is cool and all but I'd rather have good handling tbh. If you want big capacity batteries the cells have to go somwhere... I wish reviewers would take that aspect more into account because with my experiences how an ebike handles has a lot of do how much weight is placed in specific ways. Most reviewers only address a chunky bike with something like 'I didn't feel the weight' or at most 'the...

Looks Solid. Having ridden the V1 Spur for the last few years, I'm not crazy about flex stays. Since Evil isn't releasing a short travel bike this year, the Reya just moved to the top of my list for a new frame.

Love the numbers on the Reya. Going to have to put my Epic 8 Evo up for sale I think!

It doesn't seem that low. New Spur has 39mm drop in high and 47 in low. Epic 8 evo also has it around 40 in low. Maybe they also spec 165mm cranks because they are focused on the downhill vs just being a quick climbing xc bike. At least for this bike, probably want to keep the bike light, so no adjustable chainstay.
