Green Pugsley No 3 rolling!, 3 Pugsleys, all Pugsleys, but all quite differant...


This is replacing my ridged Karate Monkey 29er which i bought as a used but unbuilt frameset but only rode it twice since building it up, I like it and it rides lovely,


But i feel this now i don`t really need it having had a taste of riding 29+ with my Surly  #KramPug#  and the roll and comfort of those 3" tyres on the 50mm Surly Rabbit Hole 50mm wide rims, i class that as Fat-Lite, running around 12-15 psi... this has been the ride that has re sparked my cycling away from the coast...



Thing is i really wanted to build a Krampus to compliment this bike which is more set up like Surlys ECR for Xc riding as the Krampus is a hoot to ride, esp fast nailing it anywhere,  and i faked myself building the Karate Monkey with Rabbit Hole rims as a cheaper option to the Krampus, instead of just waiting and saving and buying a new Krampus frame when i had saved enough as could not afford it a few months back and have  little patience as cash is tight these days with still no pay rise etc..
So i had decided to sell the KM frame set (now sold) to pay for another used Pugsley frame set  when i was offered to buy one as it would be better off as another KramPug 29+ built with parts from the KM spec with a few changes to spec, and the bonus being it can be run as a regular Fatbike when needed ;) .

No Krampus?
Well not for now, but i reckon if i can ride my old (heavy these days) `Large Marge` undrilled twin wall rim Pugsleys 30-40 miles in a day that friends do on their lighter Fatbikes, then i can ride the same stuff on a Pugsley framed 29+ `KramPug`  that some would ride in a day on a pukka Krampus- yeah i know it will not have the same geometry and handling for out the saddle nailing it on trails etc... but i`m not kidding myself anymore, i am 43 years old now... not 23...  leave it to the kids made of rubber bone to honk on and take the spills, most of my cycling is sat down these days...

Building it up;
As previously mentioned  this is a used Mk 4 Snow blind Pugsley- from friend Gary Buckham that he had re coated in Landrover Olive Green,



You can read the blog post here of the offset Krampus wheels i had a go at re lacing myself having bought a Surly 135 SS hub to use on the front wheel...



The rest of the build is cheap n cheerful 9 spd Deore 2x9 gears with bash guard on old Middleburn  Rs7s that i bought 7 years ago for the first Pugsley. The square taper 100mm bottom bracket needed is an On One item i bought used on  Facebook after putting up an add for one.
Sporting 2.5" Minions on the Surly Rabbit Hole 50mm  wide 29er wheels until the 3" wide 29+ Dirt Wizards arrive, it is not a true 29+  i know, and in no real hurry for them as got these skins to wear out first :)

On Saturday the On One 100mm square taper bottom bracket arrived so i got the green pugsley rolling...


The bottom bracket has 2 bearings on either side (Phil Wood square taper BBs have 1 bearing each side), so it is a neat design and if the bearings get replaced with quality SKF bearings then it should last a long time..



Grease on the axle and on with the cranks, chain, then just a case of dialling in the mechs and it was rolling!...


Under a minute to swap wheels!- Two bikes in one...
The Offset Krampus wheels have the same Shimano rear/Surly hubs so is real quick to swap wheel sets,  no need to re set gears or re aline brake disc calliper's.
5 minutes and its now a KramPug-abet with regular 2.5" 29er tyres for now...

This bike is replacing my ridged Karate Monkey as i was just not using it, and the 2.5"  rear tyre was too neat for mud clearance,

So from this...

To this...


100mm wide Fatbike bottom bracket i think i actually prefer these days to a regular 73mm bb width, and it has reversible wheels so i can single speed it too...


And with 2.5" tyres, or 3" later in the year when the Dirt Wizard tyres arrive there is not a problem  with mud clearance...



And it rides just like my other KramPug!...




Cost?
This bike has not cost a fortune to build using the running gear from the Karate Monkey, selling some of it to change a few parts, being patient on many eBay bids until i won stuff, and keeping an eye on Fatbike classifieds for stuff going cheap...

Snowdrops are out!


With Shimano rear hubs i will be keeping the wheels out of the real wet sand on the coast, i have the old original 36 spoke Surly Marge/Hope hub wheels for doing that...


So what about my other Surly KramPug 29+?
It is still as it is, kinda my answer to a Surly ECR, and for long XC days out, maybe even some bike packing weekends this year!...
The Pumpkin Pugsley is my good Pugsley, all the best parts,  it will not see too much salt water exposure, but can if needed share the wheels of the Green Pugsley, so all 3 Pugsleys can go 4" fat on the coast.


Set up with the Jones 710mm Loop Bars i do like them for long days but prefer regular wide MTB bars for whizzing about on trails...


Offset fork with Salsa anything cage mounts anyone?  :)


Under cage bottle mount for if i use a full frame bag, TIME Spd pedals on this bike too...


The old original Pugsley;
Original Grey Pugsley (black for now)  is the run around Pug,  rear rack and Alfine 8 speed internal gear hub, Francis rides this bike when were out and i used it too scoot about, odd commute, shops etc...



All old Fatbikes, still all great bikes with years of fun to be had yet with...


Fatbikes as Mountainbikes;
Seems to be the way a lot of the marketing is heading in Fatbikes with forks and geometry for riding regular trails. I agree in places they are ace with the massive grip and climbing ability. I like many would love to ride/own the new full suspension Fatbikes like the Salsa Bucksaw, for now i can dream on... :)
Far as i`m concerned they will not replace a regular MTB for regular trail riding for most people and they will not replace frame sets like the old faith full Karate Monkeys etc..
Fatbikes will still for myself be for riding where regular MTBs cannot go or struggle to go to be of any enjoyment. Places we all have somewhere on our doorstep...
Apart from a pair of new tyres for the big Moonlander to buy later this year my cycling will be focusing a lot on my 29+ bikes  when above the high tide line and riding regular trails...
Lots more fun miles per smiles to come...

More soon...

Saturday short ride with a longer walk home!...


I cannot remember the last time i pushed a bike home, or back to the car, probably 10 years a go when i snapped a Bottom Bracket at Glentress trail centre, even then it was a one foot on the pedal freewheel most of the way down to the car park. But i got caught out this morning with a lack of preparation checking spares on the bike and shoved a Pugsley about 2 miles home!, lesson learned!

Some jets outside now at the Museum of Flight...



They will start to rot like the old Avro Vulcan is now sadly...


Through the woods, icy ruts keeping me on my toes...


And up the Ridge Road of the Garletons,  frozen solid...



All the mud at the top on Barney Hill was solid so nice and clean...



Sun on Fife across the Forth estuary...




 With no real plan i was going to explore a few field boundaries around here...

Then 5 minutes later along by West Toll Mains i picked up a big thorn, usually not a problem, pull it out and spin the wheel and it seals... but it would not seal!, the Stans juice must have used up all the particles and just would not seal!...

So not having a wee bottle to re juice and re seal, or patches i swapped the tube (re moving the thorn!) and continued, deciding to call it a day and head for home as the spare tube was not juiced and there was hedges recently cut everywhere. nice we down hill then heading east the front flatted again!...

Francis was away working, i phoned friends but just got answering phones, so walked the 2-3 miles home... at least i was nice and warmed up now!...

So Lesson learned!
Owning multiple bikes means it near impossible to have a pump and tolls on all of them, I use the old pumps and heavier tools on my 2 work bikes, and now will carry one tool kit for all other bikes,
Carry a  bottle or two of tubeless juice to top up, or add to your spare tube if you fit it- it rolls up smaller with out juice, some alcohol wipes so you can repair a tube- and some good patches and glue!,
If Schrader tubes fit a valve core remover to your spare tubes so you can juice the tube,
Carry it all in one tool bag that goes with you whatever bike, then you constantly know you have everything.
leave a tube on every bike, and a 26" MTB tube as a spare as will inflate to any 4", 5", 29er, 29+ wheel if needed as a second spare.


On a good note when i got home the postie had been and left a parcel- a 100mm square taper On One bottom bracket i bought used via Facebook, so i got the green Pug rolling!...

Surly Pugsley No3 Update; offsetting some 29er wheels...



With the Grey Surly Karate Monkey frame set now sold and posted to its new owner i did a bit more work to the Green Pugsley today with the weather being awful outside-baltic cold wind and rain.
This Fatbike frame is replacing that ridged 29er bike, and the Purple Pug and be a 29+ KramPug instead of building a Krampus this year due to funds ...
For these 3 roles this bike will be sporting 3 wheel set options: 4" `Larry` tyres for sand,  4" `Nate` tyres for mud,  and `KramPug` 29+ wheels that for now will have 2.5 Maxxis Minion tyres-with loads of mud clearance, later some 29+ Dirt Wizards when they are available,
I made the most of the warmth inside and while waiting on work to finish by friends on the Living room made use of the old carpet and done some inside spannering!...

With Al Murray on Planet Rock on digital radio i took advantage of the daylight and fresh from a day off work and i offset the Surly Krampus 29+ wheels i bought second hand a few months a go.
I am not a bike mechanic, and i am not a wheel builder, but have alinged my own wheels for years when they needed truing.  I could read up on all this but typical me i just do what people show me. I find it easier to do things showed by someone than read about it,  Friend Colin built some wheels last year for me and explained a few tips which i have since used to build a pair of Pugsley fatbike wheels a month or so ago- and they are still straight!.

Wheel building,  easy?, like laying turf right?...
Some friends have been bike mechanics and built hundreds of wheels, and can prob do them with their eyes shut. That`s easy to them, but a bit confusing to those attempting it at home!,
Just like if you imagine i sent you to build an 8ft high Revetted Turf  Bunker face on a Links Golf Course, could you do that?, know where to start?, how to cut it in?, well of course you could do it in time with confidence and experience,   It just takes experience, and patience...

Offset wheels; what`s that?
For non Fatbike cyclists reading, early Fatbikes and a few still yet use regular 135mm MTB rear hubs for offset rear wheels to allow a good chain line with that fat tyre in there. The Pugsley originally used an offset fork and front wheel too allowing to swap the wheels in the case of a mechanical issue with rear Mech, or swap gear ratios if riding the bike as a single speed.
Here you can see the offset of the Surly Pugsley frame with a regular 135mm rear wheel fitted, not much good- and how the offset rims holes shift the rim across to aline with the frame centre...


So for the rear it was an easy job of going round slackening the spokes on both sides, and then moving the disc side spokes across to the right hand holes...


So the rim looks like this-this is the old LM rims that can only be built offset with same lenght spokes...



I have not looked at Spoke calculators or anything like that yet, and just been swapping hubs and re using old spokes from the same size wheels so far, Hope hubs and Shimano seem to share the same spoke lenghts on my Large Marge rim wheels- around 262mm,  and i am just using the frame and forks to true the wheels...
Time to go round each side of the wheel and start to tension the spokes...



To run 29+ wheels (with 3" wide tyres) on the Pugsley you need to add Surly`s  `Monkey Nuts` to the horizontal drop outs if like me you run a front mech so it does not contact the tyre.
If you use a Narrow-Wide front ring, 42 rear 1x9 or 1xx10 set up you can keep the rear chainstay shorter...



With the wheel tensioned i removed it and put it on the floor and pressed down on it to help seat it, then a final true up...


And not too bad an attempt!...


The front needed dismantled to re build with a rear 135mm hub...

After dismantled i noticed each side had different lenght spokes;
296mm Disc side,
298mm Drive side

An expert will be along shortly to explain why this is-i guess is it do with it being a disc hub?...


When i moved the rear wheel to offset it one spoke side was longer then the other once tensioned as you can see inside the spoke nipples...


Seeing this i decided to fit the shorter spokes on the disc side on the front wheel. I had already measured the spokes on my existing offset KramPug wheel and they were approx 296mm-ish also so this hub swap would work!...


Two versions of the newer Surly Ultra 135 rear hub can be used on the front of offset Pugsleys-
the far hub in pic; Screw on BMX style single speed sprocket,
And the closer hub;  track cog screw on fixed sprocket...


I started left of the valve hole as friend Colin had said. Disc side with the shorter spokes-laced to drive side on the rim to offset...


 Laced up copying the Fat front wheel i soon had it tensioned and it worked out right with the same spoke lenghts inside the spoke nipples,  result!...


And here is a fixed track hub i had from the fixie build i added...



So waiting on;
A square taper 100mm Bottom bracket to fit some Middleburn RS7 crank arms and this bike will be rolling!

Also ordered some Gorilla Tape as i want to go tubeless on these rims as the Maxxis Minion 29 x 2.5"  tyres are Tubeless ready, be the first tubeless tyres i try,
Also need some BB7 disc rotors, oh and pedals... but nearly there...


Oh yeah, Revetting Turf bunkers?
Been 18 years since i left Gullane for Whitekirk- to an Inland Coastal Parkland Golf Course with landscaped bunkers!, and so i have not built a Links Golf Revetted Bunker since!, but an Elephant never forgets... :)

More soon...
