I haven't measured the gap but they're designed to take 700x45c, I'm guessing with 5/6mm space either side.
I love my Pinnacle. Mostly used as a commuter.
Mine arrived yesterday- can't wait to get out on it later 😀
I'm torn between a single or a double chain ring version.
What are the feelings and experience of people that have gone one way or the other ?
I'm expecting my riding to be mainly leisure, maybe some bikepacking but will with some steepish off road hills.
Ok and thanks
The reason why I'm Asking is because I read somewhere that the arkose will take up to 50 mm without mudgards... I have asked Evans but they can't confirm. Perhaps its not important anyway because the number of tires with sizing 700x50mm is very limited....
Are you coming from mtb or road?
Can you perhaps take a photo of the blue arkose with the 650? From above behind the bottom bracket to see the tire clearance.....

Well first outing on my 4 didn't go so well....
First tube pinch flatted 2 miles into ride.... second tube 0.1 mile later. Push home, convert to tubeless and much better, but only short ride as I'd run out of time.
Gear shifting not great and think I need to move saddle back frame seems short even though at 5'9.5 a medium should be optimal.
Hoping for a better ride tomorrow!
Go on, show us a picture of the new tourer James. 🙂
@jameso - I'm trying to convince my wife to get an Arkose but she just doesn't get on with drops.
Which Pinnacle flat bat hybrid is most similar to the Arkose?
Update: a superb morning ride on a mix of unclassified roads and bridleways and the tubeless setup worked a treat. Gears tweaked and are better and think with a couple of adjustment to bar/saddle angle it’ll be spot on.
Thinking of 45c tyres for a little more rim sympathy off-road....
Can see this machine getting a huge amount of use 🙂
Good stuff @miketroid, glad it's starting to work out.
Which Pinnacle flat bat hybrid is most similar to the Arkose?
The Neon disc - essentially a 2016 Arkose F+F with flat bars / flat bar geo. Fits up to 40C.
@sumsar81 Pretty sure the specs for clearance are 650b x 50mm and 700c x 45mm. I'll get a pic when I can but I'm away from the bike for a few days at the mo.
I had a road bike and MTB before but just have the Arkose now. It does road and off-road pretty well but neither as good as separate bikes. As long as you don't expect it to perform like a specialist bike you're sorted I reckon. I just enjoy riding more now, more relaxed, comfortable and can do a bit of bikepacking as well.
For much better detailed info the Arkose designer @jameso is on this forum, he's the font of all known Arkose knowlege!
I've had the 2018 Arkose 4 for a few months. Great bike for commuting and weekend off road rides. I've take it a few times on 4x4 tracks in the Cairngorms National Park, and it's handled well.
Once thing I noticed is a clicking/popping sound coming from the rear of the bike, which has occurs since it was new but has gotten louder over time. Apparently there been issues with the freehub in previous years models, so it might be related to that. Handed it in this morning to Evans for an inspection, so will hopefully get it sorted.

Apparently there been issues with the freehub in previous years models, so it might be related to that.
That was a single batch issue on KT freehubs of an earlier design, but still with getting it checked. Most likely a bit of grease and torque needed somewhere.
Am I going to get these on my 2015 Arkose 2?
Seemed to cheap to pass up, the specs on the Q&A on the site for the bike suggest the hub is 135 at the back and 100 at the front.
I believe the WTB 40c nanos are on 17mm rims by standard.
Looks like the tyres included with the wheels are 2.25 and on 19mm rims.
Plan if the tyres can't go in, is to put my 28c tyres on the stock rims for road use/turbo training, and I'll move the Nanos across to these new rims?
Thanks
@jameso I hope you can clarify the stock situation, I see that Evans website is saying no Arkose 2 until October, is this a realistic date ?
When would the 2019 colours / model be released ?
Am I going to get these on my 2015 Arkose 2?
I very much doubt it, not a 2.25. It would be a skim-fit on the current bike that has the new fork. Sorry...
@jameso I hope you can clarify the stock situation,
I can't sorry, better to ask via the website as the team who have stock ETAs can pick it up. 2019 model ETAs will be November or so, we don't have really early model launches in July etc.
No worries thanks for the reply. The existing WTB nanos can go on the new wheels, I'll stick my slicks on the original wheels, and I'll have a hunt for a cheap cassette and pair of brake rotors. Hopefully don't need anything else but it's been a long time since I've assembled bike bits so off to YouTube I go.
I'll stick the other tyres on eBay to make a few quid back.
The tourer looks fantastic - brilliant spec and silly value - didn't realise it was out 🙂
Looks proper classy too. What's the tyre clearance like James?
Impressed you've got rid of the toe overlap, so many don't bother and the gearing is spot on.
Nice one.
Ok 👌 and thanks...
I have discovered that the wheelsize 700 is the same as a 29er so a small 29er mtb Tyre will fit the arkose ... Any one who hav tried it?
Is it worth the extra 450£ worth to buy the arkose 4 instead of the arkose x....coming from mtb I don't know anything about the specs on the bikes other then brands and so on....will at handlerbar like the salsa cow bell fit the arkose? Perhaps the hose will be to short but is there anything else I'm missing?? Cheers and happy trails
@sumsar
I think it’s worth going for tubeless ready which the 4 (poss the 3) gets you over the X...
I had 2 pinch flats in the first 2 miles of riding my 4, so I went tubeless (took minutes) and it’s much better.
I've just bought a Pinnacle Arkose 4
Has anyone had any luck with 650B wheels and 50mm mudguards?
If so, what combination of wheels and tyres have you used please?
Quick question - does the 2015 Arkose 4 have a qr or 12mm axle on the front wheel?
Thanks!
Ian
But the Alex rims on the arkose x is tubeless....
@sumsar81 thye Arkose 4 will have a bigger spread of gears at the back (useful if terrain is hilly - duh) and the gear shift is part of the brake lever, instead of being at the bottom of the drops. The gears are also 11 speed.
Jameso with apologies I need your guidance again.
As you said, those tyres were too thick for my Arkose 2 2015. Not a problem, I’ve moved the stock WTB nano 40c ones to the new rims, along with the existing brake rotors.
This is where I’m a little stuck, all with regards to cassette spacers. I moved the stock SRAM 1020 (presumably same as 1030) cassette across as well. Compared against the other wheels, it seemed to sit at the same height. Torqued it down to 40nm.
In the bike repair stand, in 9th gear it almost feels as if it’s not indexed properly. But it’s fine on a ride and there’s no free play in the cassette.
So long story short - are the stock alexrims/joytech hubs designed for 10 or 11 speed? Assuming they’re 10 as there was no spacer behind the cassette, if I pick up the Shimano HG81 from Evans, for the original wheels, do I need a 1mm spacer?
I’ve got an HG81 on my MTB that I converted from 3x8 to 1x10 and that didn’t need one.
thanks
edit: or does all this spacer stuff only apply to road wheels? 🙂
or does all this spacer stuff only apply to road wheels?
Correct, top marks.. 2015 bike has a 10s freehub, as far as I can remember w/o spec detail in front of me. Pretty sure tho as 11s was a way off the Arkose 2 level then. Fwiw I find even when swapping between 2 Shimano 10s cassettes of different ratios I often need to adjust the gear cable tension a little.
Fab thank you. I think I’ll just grab another SRAM cassette then to keep it consistent.
Anyone run a 2016 Arkose with 650b wheels and tyres , hows the clearance on the forks ??
After reading various threads about clearances etc, decided to treat myself to some Hunt 650b wheels and some Maxxis re fuse 2.00 tyres, all went well, up first time tubeless , rear has bags of room but front has probably 2-3mm max clearance either side 🙁 ... not happy as bit too close for comfort,.... time to change the tyres or the fork ??
Jameso ... do the later frames have more fork clearance ?
cheers
I'm running 650b with Re-Fuse 2.0" on a 2017 Arkose. Loads of room front and back.
@sumsar.... so they are!
@ mounse 701 , Must be the difference in years as mines a 2016, any chance of a pic of the fork clearance you have please ?
cheers
Stumpym4, yes, we specced a new fork for 2017. 5mm longer with loads more crown clearance. Rear stays are about the same. In 2016 there was some good stuff being developed for 650B so the changes were made then.
Cheers jameso, so my options are , new frame set , new forks and or different tyres ! ... I even spoke to stu from bearbones , as he has an older arkose and they fit his just fine ??
The older 2012-13 fork had a shade more clearance in the area lower down where a 650B tyre shoulder sits.
I'm still getting shifting issues (mainly in second gear which occurred from new) and have noticed the jockey wheels don't line up with the sprockets (The upper wheel sits outboard of a line between cassette sprocket and lower wheel)...
Am I right in thinking they should all line up, or is this a SRAM thing?
It's done 4 rides and hadn't had any impact to bend cage in at bottom. Shop time? 🙁
Can anyone comment on a decent set of comfy winter tyres, and some good fitting guards that they’ve used for the Arkrose?
im coming from Conti GP GT’s 25, looking at the same in 28 tbh...
I got a set of these:
which were a doddle to fit and seem to be fine, although I've only had them about a month so no idea if they actually work in the rain 🙂 They don't rattle and there's loads of space round the 33mm tyres I've got.
Also, I've been using specialized roubaix tyres and they seem good and not too pricey.
Can anyone please tell me if new models is on the way this summer ..?
Don't want to buy one if there something "nicer" on the way?
Cheers
I need a new bottom bracket, and a tool to remove the current one and fit the replacement. Will any of the normal external bottom bracket tools work? Also, I've seen the Samox one on the Evans website but it's £30 which is more than I can bought they'd be. Any suggestions for a good value/quality replacement? Shimano would be fine
its a 2015 arkose 2
Ive fit up to 1.8 29er tires and a cowbell 3 (trp mechanicals) on my 17' arkose.
Here is another photo of the Pinnacle Arkose 2, 2016.
This is so cool info big Thanks....
Do you remember the tire ? Big side knobs?
And do you have pictures of the cowbell and the tires?
Cheers Rasmus
Quick update on my creaking bottom bracket. Bought the park tool bottom bracket tool and a new samox BB from evans. Installed it last night - pretty straight forward (once I got the rubber/plastic mallet out) and the park tool worked great
oh, go on then, here's another photo. I've taken my pinnacle away with me on holiday to the south coast.
Hi folks,
I'm very tempted to get a Pinnacle Arkose X for my commute/general dicking about when I don't want to ride my MTB... but was wondering, how easy would it be to convert to SRAM Apex or Rival 1x11? Alternatively, are there any Shimano offerings in 1x11, if that would be easier/cheaper? Sorry, I'm out of touch with the latest developments over the past few years! 1x10 was still the new thing when I converted my Mega 😀
Cheers,
Lee
Sorry RS, missed this,
The tourer looks fantastic – brilliant spec and silly value – didn’t realise it was out
Thanks - no fanfare launch needed, just a tourer isn't it ; ) they sell steadily in stores and that's that. I like bikes like that. Tyres are 35mm w/ guards as std, with loads of space. Road/tour 40s would fit. There's more space up front if you wanted to put a bigger front tyre on it.

The Arkose 4 with SRAM 1x11? Converting the Arkose X would involve a new rear wheel / wheelset, brakes and transmission. The aim of the Arkose X is to do a similar job, with brilliant hydro brakes, at a lower cost (and we had 1x with hydro out a couple of years ahead of the SRAM CX 1x11 so we're keen to keep the format in the range)
@jameso are there any ss arose still available?
Sold out now sorry. A shame, I think it had one of the best paint jobs we've done and I didn't grab myself a L before we sold them all. We do have Arkose Alfine framesets though, basically the same thing, an Arkose with a pinch-shell EBB.
Can anyone please tell me if new models is on the way this summer ..?

New models due November ... like when new model year bikes used to come out, before 2019 bikes got released in June 2018 : )

Thanks for the reply James.
The 4 is over budget sadly (limited to £1000 C2W voucher).
A new wheel? Why is that? I’ve swapped between different speed SRAM and Shimano cassettes on my MTB wheelset (Mavic Crossmax ST) with no issues.
How about adding a XT 11-42t cassette and one of the 11spd Shadow mechs? Can the bar end shifter accommodate an extra gear?
