Review: Kona Jake 2015

Kona Jake, 61cm. 2015.
One month on, and it’s time to summarise my experience so far.

image

Fit: it’s big, but I need that. The choice was narrowed down to a ‘cross bike with disc brakes and mud-guard bolts. This is not the biggest Jake, the catalogues list up to 63cm, which must be huge. At 6’4″, I have always needed a large frame and reach has been a particular problem. That is why my first two bikes were custom made. Off the peg at the time, it was only possible to get 22.5inch top-tube bikes. Many famous brands made all their frames with the same top-tube, regardless of frame size. This 61cm fits me well.
Handling: it all seems natural to me. Squelchy surfaces are a new experience for me, and I don’t mind admitting to some nervousness. That’s my weakness, not the bike’s. My nerve and judgement is getting better with each ride. Once I have fallen off, I can truly say the bike is christened. However, the canal water looks very cold, so the first tumble better not be into the drink.
Weight : with the bottle and seat pouch removed, it’s 10.57 Kg. About the same as my steel 8 speed racer.
Brakes: at first, it needs a lot of pull to stop hard but once a hundred miles were done, they became excellent. The cables don’t need to be all that tight, unlike the setup by the shop. After loosing them off, the braking is sensitive and subtle with the option to weigh anchor if necessary .
So far so good, the only problem is the brake calipers. They are quite wide so my heel catches on the rear brake sometimes. Once I have paid the last installment, I will change them to another brand. Bikes with rear brakes mounted on the seat-stay won’t have this problem, but their owners will struggle to fit a rack.

Wheels and tyres: not light, the rear complete is 2.2Kg. They do seem strong and the tyres grip well on soft muddy trails. The only real frustration is the large number of punctures. In first 120 miles ridden so far, 7 punctures. 5 were caused by thorns, the remaining two were snakebites. Soft grass and mud can conceal a deflating tyre which is probably how the tubes got pinched in those cases. #1
Gears: 10 on the back (11-30) and a double chainset (50-36). The Tiagra change reasonably well but one cog is slow to click down. That cassette is huge, 11-30 and is probably heavy (see above). #2
In future I will fit road wheels which will have higher ratios. Perhaps 11-25 would be more realistic. This way, if I fancy some muddy fun, then it’s only a quick swap away.
The down side: there are only a few changes I would make to this bike:
Handlebars- I don’t mind the wide bars, but the drops are quite shallow so that with hands there, your position is no lower than on the tops. You can’t really get your head down on a fast descent but at least you can exert leverage with the wider bar section. This shape, it seems, is the fashion these days.
The rear stays are rather plain; they look like they’re from a 1990’s bike. No curves or wishbone design. That is all behind you so you can’t see them though, so don’t worry. The bottom line is that when you’re on the bike you look at the landscape and traffic, when you’re off it- the bike is locked away in the shed. Looks aren’t that important.
Finally, the seat is too narrow for my big arse, and the stem, 1cm too short.
Overall, Remember that I have never had a mountain bike and am not comparing a range of machines like a proper review might.
I am having tremendous fun with it and probably building handling skills on loose surfaces. Without a doubt, it’s a fine 50th birthday present to myself.

Towpaths and punctures.

5°C, lighter, calm.
Unwanted side-effect, punctures. Just patched the tube that went down yesterday, it had two holes and needed two patches. One was a snakebite, probably from the moment the nail punctured and pinched the rim against the road. It’s not so obvious that the tyre is going soft on soft round.
In the meantime, both tyres on the bike have gone soft overnight.. At least two more punctures!
That averages out at nearly two per ride. Sigh.

Tyre liners, change tyres or some of that goo that seals from the inside? What’s the best idea?

Dense fog.

4°C, dense fog, no ice.

Horrible day for a road ride. Dense milky fog and cold. On the route to the canal start I crossed a few small groups of roadies.

image

My conclusion from today is that cx rides are quite viable when otherwise I would have to return home. Canal towpaths, though a place to pick up punctures, are much safer than the road in poor visibility.
In all, I probably clocked up about 5 miles on tarmac. Just as well because the surfaces were so greasy and slippery.

image

Today’s puncture was a nail, not quite what I expected on a canal but at least it happened near the end.

Touring wheels.

-2°C, Clear sky, light NW breeze.
Cold commute tomorrow. Fitted the new rear wheel for the ride. Very low temperatures are forecast all week. Bitter.

Here is another photo from Sunday’s outing on the cyclocross bike. Here, I am riding back from a dyke on the shore of the Ribble estuary. It looks like a flood effort on the edge of mud-flats. It’s a large nature sanctuary, dull of birds I don’t recognise.
With hindsight, I should have practised moving mounts and dismounts. It’s a competition technique for CX races but would also be useful on soft grassy land too. Like a roadie, I get on and pedal off. Trouble is, the first turn can spin the wheel. If you trot along then get on, you already have momentum to balance.
Next time…

Mud and a dyke

The canal section left me with a puncture to fix. I rode a good 2 miles before it needed a top-up. This tactic didn’t work for long, as ever. Deflation accelerated so the tube had to come out. Ironic because I stopped to chat to a guy who had just repaired a flat by the canal.
The calorie counter above may need some adjustment to account for the slow surfaces today. Average speed was only 10mph, about 5 lower than a road ride. At least the speedometer agrees. I shall write a post about this speedometer another day.
Anyway, I can now see why mountain bikers are often the last to change shorts for longs in the autumn. Off-road seems to offer the best shelter from cold wind; speed is lower too.
Maybe 6,000 miles this year is unrealistic.

Deore wheels.

Light snow, 2°C, North wind 12,
You have to trust your wheels. The rim years the most and that’s where failure is most likely. The braking surface becomes thin with years of braking. Once thin, the surface can fracture- I know, the happened before. The tyre pressure exerts a strong force outwards, so breakage most often happens just after inflation.
What I really don’t want to have, it a failure 20 miles from home, in the dark. Nightmare.

image

The idea that led me into the bike shop was to replace the rim and have a re-build. The old hub gap been rebuilt half a dozen times, had several axles and free-hubs. So I came out with a new pair of wheels. Confidence. Shimano still make the same hub with the same bearings as the old STX hubs I bought in the 90s.

Mud and sand.

Slow average speed, but hey, it’s off-road. I took a canal towpath to to the Sefton Cross pennine route. It’s a disused railway line which runs up to Southport. Perfect terrain to try out my new cyclocross bike.
image
Then on along Southport sea front to the north. At the end of the sea walk is a short track that usefully cuts out a busy roundabout. But I witnessed an unfortunate scene. A hawk, disturbed and took flight along a ditch, in its claws it carried the still live body of a songbird.
After passing the familiar landmark Martin Mere, I made my way back along the same canal towards the start. The bridge I left the water looked like the first one but led to a public footpath. I hope I was legal riding on that route between fields.
Negotiating paths like that demand non-stop concentration, especially the bit past The Saracen’s Head. I really didn’t want to fall in the canal in front of that audience. Next time, make sure your phone is in a waterproof bag.
image
The whole route was within the bounds of familiar routes, but it felt like I was travelling on new territory. Often, I could not be sure where I was, which canal bridge was coming up or how far remains.

N+1, Kona Jake,

7°C, sunny, light SW breeze.
Finally it’s mine, I bought the Kona Jake today.
image

It features disc brakes, chunky 32c tyres and 10 speed cassette on the back. I took it on a test in the middle of the city and immediately, the size felt right.
Looking at components, I will have to buy some new tools. The shifters are the same as that bike I hired last summer.

Tomorrow, I will ride it in more realistic terrain than the streets of Liverpool-1 this afternoon.
