Pinnacle Arkose Three (jameso to the forum please)

What fork is this guy running? Would be interested in an Arkose if I could run low loader front panniers on occasion, everything else about the bike ticks the box’s for what I am looking for

What fork is this guy running?

Stock 2015 Arkose spec. The rack fits to the axle and the crown eyelet. Think it’s a custom / locally made rack tho. The current fork has an eyelet at the brake bridge location, if there was a caliper brake there.
Carbon fork and front low-rider combo would rely on having a rack that’s axle-mount and doesn’t clamp to the fork. The M5 mount on the blade is only for a guard, deliberately placed too low for a low rider as it’s not designed for it.

Thanks, looks like no front loading then

Slightly random question. On the 2017 Arkose two (a 2×10 setup), there is a widget clamped to the seat tube below the front mech, it has a protrusion almost like a coat hook and looks like it might be some sort of thing to catch the chain if it drops off the lowside. Is there anything more to it? if not I’ll remove it

It’s there to catch the chain if it falls off. It weighs nothing, why remove it?

Had a couple of rides this weekend on my ’15 Arkose 4; such a capable bike.

Pic for no reason.

Anyone tried to road plus his / hers 2016 Arkose?
I’m currently running 40mm WTB Nano’s on a 21mm internal rim but for the summer I’d like some more cushion. Out back there seems plenty of clearance for a 650B 2.1 racing ralph, or 2.0 race king or similar fast XC tire. The fork seems to run a bit narrower but I reckon I still got about 5mm of clearance on either side so I’m wondering if a 50mm 650B tire would fit. I’m guessing the widest part will come a little lower than the widest part on a 700c tire. And I keep reading specs for other bikes which state ‘will fit 700×40 or 650×2.1’, does this count for the arkose as well.

Apart from all that, I really dig my Arkose. Used it for cross this winter and rode the Flanders full sportive on it. Really impressed with the frame. The only negative is the paint, it seems to chip rather easily and it shows rubbing marks form my framebag something I don’t get on my other bikes. I wonder if it has got to do with the matte finish compared to a shiny one.

Hi again – question for Jameso if you’re around re sizing.

I’m just over 5’11”, with an 88cm inseam (I think, something above 34.5”) and slightly longer arm span than height (184 v 181cm). Judging by the size chart, I’m assuming I’m on a large?

Thanks.
Ben

My Arkose at the weekend in full bikepacking mode for this years WRT 🙂

if you could check the 2016 ss frame with the WTB Byways that’d be great.

Later than I hoped, sorry. BHW and being away last week (WRT also Stumpym4, I saw you roll up on what I though was an Arkose) … No go – well it will ‘fit’ but only with 3.5-4mm at the sides with a Maxxis Re-fuse on 21mm rims. The Re-fuse casing is the ~same as the Horizon at 46-48mm depending on the rim.
But there’s hope – I think a bike like this that works well on 700×40 and isn’t CX race geo also works well with the 42C 650B tyres like the Panaracer Gravel King (belted version). Handling is a little less floppy than bigger 650Bs can make it (tyre size/shape affects handling feel). BB gets a little lower, similar to 700×23, if you don’t pedal round roundabouts and use SPDs not flats it’ll be OK but it may be outside the ISO 25 degree lean angle regs. I’ve ridden lower BBs and lived.

I keep reading specs for other bikes which state ‘will fit 700×40 or 650×2.1’, does this count for the arkose as well.

2017 Arkose yes. 2016 – 42s fit, maybe 45 max. Horizons are too close in the fork imo.

Ben – yes, Large. We can exchange within 30 days if I’m wrong but I’m pretty confident you’ll fit it well. I’m 6′ with similar leg/arm reach and fit the L well.

Excellent, thanks James. Looks like decision made!

Cheers.

So a 2016 Arkose is it definite no go with WTB Byway’s or is it rideable with 3-4mm clearance?

Just seen the Alfine Arkose…… looks like the perfect machine for me that I didn’t know I needed until I saw it!!

Just because I learnt how to post photos, a pic of my arkose. Gets used a lot. It’s just a bike and I love that.

It’d clear the fork in the dry, just. Best if you’re fairly light. I reckon I could get the tyre brushing the side of the fork if I tried but I’m 6′ / 12st. But ISOstandard min clearance for road tyres is 5mm .. MTB is 6mm. So officially I have to say no-go. The 2016 bike has 72mm bb drop though (more on 2017) so a 42mm Pari-Moto fits fine and the BB height is OK, that was what I was using before WTB made 47mms.

This? 🙂

Like my old Day One Alfine .. just a fair bit lighter. 2017 frame so takes 650s too. Byways on Alfine?

That’s the one! Love it!!

Idle musing: Could one fit a 2017 fork to a 2016 bike (colour aside)? Did the front end geo stay the same?

Does anybody know which model FSA BB I need for my 2014 Arkose 3?

Sorry, missed this at the time. 2017 fork is 5mm longer to clear a bigger tyre – yes it’ll fit, but it will raise the 2016 bike a bit and have a minor effect on handling.

@phy7tes, it’ll be the standard road MegaExo if the bike has an FSA road crank on it. They’re all the same dimensions.

Thanks for this. Seems that there are a few MegaExo models though: omega, gossamer, gamma, v-drive !! Any idea which one I need? Cheers.

I gave up looking for an FSA BB when I saw the prices. Ended up buying a Shimano CX chainset which came with BB for £65 safe in the knowledge that new BB’s are only a tenner or so.

Does anyone (JamesO?!) have any idea of the weight and a2c height of these(currently out of stock)?

They look like a well priced fork for a gravel bike, only other similar ones I’ve seen are the Selcof forks from PX, but they don’t have guard mounts

Both answers to your questions are on the page you linked to…

Check the questions section.

cheers bruvva!

800g fork weight. Seems a bit high….if anyone could confirm….

800g seems out, the al-carbon version is around 750-800g – the full carbon versions are around 550g from memory. They’re made by ADK, good forks.

Thanks, James. I’ll banish that thought then. I feel so at home with the handling that I’d hate to do anything that changed it, minor or not. :thumb up:

Cheers James.

I took a plunge and went for it: Ritchey Vantage 650B wheels (21mm internal) and WTB Byway tires.
After a week or so on the wheels they come out at just under 47mm. It’s a tight fit, about 3mm clearance, but I’m rather light and I only intend to use them in dry conditions. I’ve tried hard but I can’t get the tires to rub my fork while riding (I’ve placed some protective strips just in case).
I have only done one gravel ride on the Byway’s but they do what I expected them to do: roll well on the road and soak up the bigger hits better than my 40mm Nano’s offroad.

While we’re on the subject of wheels what maintenance can I do to the wheels on a 2016 arkose 4 in terms of the hubs. The front has gone that rumbly way that suggests the wearings are dry. There’s no play in them but something doesn’t sound right.

I’ve had a creak on my 2015 Arkose 4 since day one. I’ve stripped the entire bike since, had the recalled derailleur hanger replaced and even evans had a look in the early days and replaced the rear skewer with a shimano one. It occurs when pedalling and I’m half inclined to think it’s the wheelset but don’t have any others to test it on.

I had the issue which the hanger was recalled for where the rear wheel slipped out of the dropouts when putting power down and the frame has since been damaged. However, don’t think that’s a factor….

Anyone with a similar experience?

I’ve had my Arkose X for a month or so now – really enjoying exploring local lanes, byways and bridle ways.

Provo – where did you get the Ritchey wheels from? Do they adapt to 12mm through axle out of the box or did you need to buy a conversion kit?

I was looking at Hunt 650bs, but they’re only 19mm internal width, which seems like a backwards step from the 21mm 700c rims I’m running with WTB Nanos at present.

Cheers

Here is a short video of me and my Arkose. Its just to celebrate the Joys of a spring evening. Filmed with my phone propped up on pebbles and held in my hand…

@ benmullard:
The wheels were on sale at chain reaction cycles. As they are MTB wheels they do not come with adapters, the front wheels is 15mm but I believe Ritchey sells 12mm end caps. My arkose fork is 15mm. They are 21mm internal and would I have had more clearance I would have even gone wider, probably 25mm internal.
The only issue I have my 11 speed sram road cassette doesn’t fit the cassettebody. I think a ritchey road body would work but for now I just removed the 12T sprocket.

Are there any disadvantages to picking up the current Arkose single speed to then at some point transform it into a 1×11 build? Will be mainly for commuting for now and then the random adventure now and again

I just love the color way much more than the geard Tiagra build

I’m going to be buying it through Cycle to Work

Provo – many thanks for the info.

Jameso – if you read this – what rim width have you used with WTB Highway / Byways?

Cheers both.

Has anyone got an XL frameset they need rid of?

M4xime, not really no, has ability to take a rear mech with the right hanger fitted.

Ben, WTB i25s here. Had some 20mm Pacentis which were fine for 42c but see nothing apart from a few grams against the 25s now there’s bigger tyres available. Either works ok though.

Tease us a bit more about the steel version James….
🙂

Thanks James – I took a punt and have a new set of wheels in the garage with i25 rims, just waiting for the Byways to arrive from Germany as I have everything else ready and waiting. Will get some pics up next week. Am also planning on getting some more road oriented tyres for the original wheels to cover most of the bases.

Cheers
Ben
