How does the size of the chainring affect how close the crankarm is to the chainstay?
I suspect brant is off to compare with a built bike in the warehouse - dimensions and chainring/crank arm location to yoke angle / spread.
Max chain ring size is 32t but that's got nothing to do the crank Arms. I'll have a look at mine and upload a photo.
I can’t see them shipping bikes with clearances that tight
Unless either the frame or crank flex a lot then clearance is clearance surely.
Is there any reason you couldn't put a spacer on the BB? I thought most cartridge BB's still used one to allow for an e-type front mech or chain device.
Might take mine appart later, just looked at the SRAM manual and dont remember the 4.5mm drive side spacer, but do have a 2.5mm bb spacer on there.
How does the size of the chainring affect how close the crankarm is to the chainstay?
The chainring looks to be 50mm from the centreline. Which means it’s 2mm inboard of boost spec. Which means the whole crank is 2mm inboard. Which means the BB axle is the wrong length if I understand Powerspline correctly.
Bottom bracket is 118/73. If they did a longer axle I've not seen one. It's marked 68 etype, 73 std no spacer. I tried a 2.5mm spacer and whilst there's more clearance, the nds cup has to screw in a long way to support the nds bearing. Everything should fit fine, chainring to centre is on spec. It's just odd how the chainstay curves out towards the crank arm where it joins the cast yoke.
Im playing around with my chainline. I currently have a 2.5 spacer on the non drive side and clearance is OK, could be better. Running a triple xt 175 with hope chain ring.
When I threw the bike together I didn't even measure the bb to see if it needed a spacer.
Just looked on the website and it's BSA 73mm so doesn't need a spacer 🤦♂️

The non drive side has plenty of clearance

Pre emptive question whilst on the subject of offsets:
Whats the deal with direct mount chainrings. If they come inline +3 and +6mm. Do I want an inline one if the cranks are already boost, or are the cranks all the same and I want a +3mm (or +6mm) chainring?
Just looked on the website and it’s BSA 73mm so doesn’t need a spacer 🤦♂️
don't think that's right.
68mm shell, 3 no 2.5mm spacers. two drive side, one non drive
73mm shell, 1 spacer drive side.
The spacer allows for swap out with a BB mounted front mech (e-type), if you remember those things.
Have set mine up with no spacers at present as had read somewhere that was correct for 73mm shell.
Is the general consensus that should have 2.5mm spacer drive side then?
Yes - 73mm has 1no. 2.5mm spacer on the drive side.
No, DUB is different to the older BB's.
73mm is either 1x 2.5mm spacer (or chainguide) and a 2mm axle spacer, or a 4.5mm axle spacer.
Speaking of, lightest/ cheapest chain guide? I test fitted my old straightline silentguide but it doesnt like the 12s chainline.
No, DUB is different to the older BB’s.
oops, missed that it was DUB.
This is why I bought a complete build for the first time ever; I have no idea about all these new standards. Last time I built an MTB it was square taper triple..
FWIW mine has about 5mm min. clearance between the DS stay and the crank. GX Eagle, DUB etc (whatever that is).
I initially fitted mine with a spacer on either side of the BB but as I'm using boost converters on the rear hub the cassette was to far inboard and the chainline was off. So whipped the spacers off and the chainline was fine and still enough clearance for the crank arm.
How are folk getting on with these? How do they compare to similar bikes? I nearly bought one at £999 which makes it near impossible to pay £1199...
Nobodys got one in a rideable state yet. For an extra £200 they might pack it properly.

I’m loving mine - on both riding around local tracks and towpaths etc plus a run around Llandegla it’s just a whole heap of fun to ride. I went for the GX build with Mountain King tyres when the pre-order discounts were live and added a Brand X dropper.
I can’t compare it to other £1k bikes but I do know I like it !

There are loads of built bikes and happy riders. A few bikes have had some issues but px sorted them straight away.
A few of us are messing around with chainline and crank clearance but we've built from frame only.
Personally I'm loving mine. I think it's great. Exactly what I was after.
like markwsf i have the gx build with mountain kings and have added one of those canyon droppers off ebay . Have also swapped the 740 carbon bars for some 780s i had in the garage and after 1 ride i knew the saddle wasn't for me . I seem to of got lucky and mine turned up with a straight mech hanger .
It has the same feel , geometry wise , to my flare max so i felt pretty comfortable on it straight away . It feels great on singletrack and feels like a pretty solid all rounder . I wouldn't mind getting some big rubber on it .
I really fancied a bird 29er or a solaris , my recent bike buys have been to replace my stolen bikes and i used a good chunk of the insurance money on my flare max so i was after a cheaper hardtail and you dont seem to get a lot for your money these days so with the presale discount the on-one fitted what i was after .
Any fork deals around or anyone spotted anything good 2nd hand? Missed the bargain PX ones?

That's why I got the preorder as soon as it started! I knew I'd just procrastinate and dither waiting for an inevitable sale and get massive FOMO otherwise.
The £200 extra does get a nice wheel upgrade. So just convince yourself that you would have thought the fulcrums too heavy/narrow.
The only way I would have been tempted to wait longer would be to buy a frame and build it up with a Shimano drivechain. But unless you get lucky with a fork and have lots of good kit spare I don't think it's possible to match the spec for <£1200, especially as micro spline options are limited.

Decathlon seem to have the Judy's for a good price, although as usual their spec is missing on the website so they might be the even cheaper version, they're just listed as "spares for rockrider......"
Merlin have Pikes for £400, but they're not boost.

Do we think the Decathlon are Boost spacing or regular, can't even find hub width on the bike they are listed as a spare for.
Edit - I think I found that it is!
Some frames half price. I can't see what size though. £125. You might have to watch the video for details
https://www.planetx.co.uk/i/q/BNFR66/planet-x-bargain-frame-66---scandal
66 is sold
67 is a large.

Mines rideable after some gentle persuasion to straighen the hanger. However it's done nowt but rain since, and will continue for the foreseeable, so I've only ridden it once. Wrecking drivetrains, brakes, and fork seals in the wet sandy mud round here was one reason I stopped riding MTB for years, moan moan moan.

Procrastinate is my middle name! The things that slightly put me off were the narrower bar and having to source and fit a dropper.
Thanks for the views everyone.
Really enjoying my scandal...
I can only really have one bike, so thought I'd try and make the scandal 3 bikes by having 3 sets of wheels 🤔
29er with the supplied fulcrum wheels and gx cassette, 2.5 dhf and 2.4 dhr. Xt ice tech rotors
Gravelly Roadie thingy with superstar clearance wheels (hence random colour!) with extra October offer for 70quid delivered, fitted with a 2.1 thunder burt and a 45c riddler. ebay 203mm discs at 8quid each and a nx 12 speed cassette from ebay
27.5+ m1900 I had in shed with 3.0 trail boss and 3.0 vee Trax fatty thingy found on ebay. Also with ebay 203mm discs at 8quid each and a nx 12 speed cassette from ebay

Had my first 27.5+ ride today on our local trails and I was very impressed, comfy, rolled well and not as slow to respond as I expected... I think brant was onto something when he showed us his scandal on 27.5+!
Going to fit a 34t front ring to see if I can get a smidge more speed when out with my gravel bike riding mates.
If it helps previous ring related queries, it came with fitted a 32t 3mm offset boost ring.
203 rotors fit 😮
Yes, no issues with 203mm...i presume that wasn't a design criteria 😁
No!
Just seen it, fame at last... 😁
Thanks brant 👍🏽
I better not let Mrs EV see this I will have to sell 2 of my other bikes!

Nonsense, just buy more.
Future me: "these new bikes?" "No, I've always had a 27.5+ bike, look at this photo from 2019".
Quite liking mine. Done about 200km on it. Doesn't feel anything like as cumbersome as every other 29er I've ever ridden. Haven't done any proper gnarr on it yet, because I'm still playing with fit.
It's made my 650b Explosif feel even more fun, too.

Just finished my new Scandal. Took most of the parts from my old Niner SS which broke. The fork is only 100mm adjusted so the geometry is a bit flat at the front but then it’s only intended for slipping around in the depths of winter. Might get a suspension fork for it next year but seeing as I have a carbon Niner for racing then maybe not.
Ive had a few rides on my scandal now. For how much i paid im pretty impressed with it, Was built as a winter hack from my spares box so is a miss mash of parts but its ideal for the winter slop.
Its a bit sh*t up after yesterdays ride 🙂 but heres a couple of pics.
Anyone know the weight of the two builds?
NVM, just checked the website, 28lbs for the GX.
Does that stack up in the real world?
Hi,
Just in case anyone is looking at a new rear maxle this ktm fits. It is slightly too long but the thread starts and ends before and after the on one maxle. I couldn't find a better match for the price £20 delivered. My lbs had a ktm bike in and we tried it for size. Sorry about the pictures (on my ebay app it's free postage but on the below link it's £15 postage)

Finally got my new wheels built, stans flow mk3 rims with schwalbe nobby nic 2.6 tyres. They didn't come up as wide as I was expecting but they are a fair bit bigger than the maxxis 2.35 I've removed. Based on the profile I think I could squeeze a 2.8 in and still have mud clearance. I reckon the genesis tarn fork might fit a 3.25, there's loads of clearance on that.
Ignore the slightly rusty chain and the dodgy routing of the brake as the cable is slightly too short. It's a winter bike!

Been out a few times on mine, mix of woody singletrack and open moor.
I'm still not 100% certain if I like it.
I'm hoping it's new bike fettle syndrome, and I just need to get my position sorted out, but it feels quite sluggish, maybe going this slack actually wasn't for me after all..:-/
Front end feels a bit wandery, OK on the down, with the wheel weighted, but undulating singletrack is quite a handful.
I ended up sticking a slight layback post on, as the forward position didn't feel comfy and made me feel a bit cramped whilst seated (I'm on an XL, and 6'2, long torso, short legs), that didn't feel quite right, so upped the stem from a 50mm to a 60mm to see if that helps.
It seems to have a bit, and I will persist as I suspect that I just need to lower the front end until I get the correct balance on the front wheel weighting.
Still, if I need to sell it on it's not going to be a huge financial loss..just time off the MTB..
I'll report back in a couple of weeks 🙂
I'd built mine up from bits I had in stock and felt kinda the same as you, until I swapped out the 720mm bars I had on it for some 780s. That, and swapping from 36T to 30T up front. It has transformed it. Although I think 32T might have been a better bet.
Thinking of getting one of these frames to build up, at 175cm tall as usual I seem to between sizes medium and large, better to size up or down on one of these? A different frame but had a PEX London Road a while back in medium and it felt a bit too small even when altering saddle layback, stem etc. Erring for large size - any advice? Cheers

Im 175 and went for a large.... but in a way I reckon an XL would be even better.
