Surly Wednesday Update; replacement gears for summer....



I really like my Surly Wednesday Fatbike, it`s ride and simple 1x gearing.
I was also able to build the bike to a budget. Before i re laced the wheels to the tubeless rims the bike was built for under £500 (Not including the frame set and Halo wheels).
I did splash a bit of cash on the Shimano 1 x 11 drive chain rather than opt for the cheaper Shimano 10 speed Zee  mech and shifter,  Sunrace do a 10 speed 11-40 cassette which is also an ideal cheaper cassette option for  keeping the spending down,  Note the Zee short cage can only mech can only go to a 40 tooth rear while the XT 11 speed then went to a 42tooth,

Anyhow the XT 11 speed drive chain for the extra cost has never really impressed, and i have never managed to get the gears to shift real smooth -though the gears are a nice spread for my type of riding on the coast. Chain angle is scary to look at and the narrowness of it prob explaining the short chain life.
Buy a chain checker tool and use it often!.

3 chains to the first cassette in the last year before the cassette have shown ware in not a lot of miles,
I decided  to renew the cassette now and chainring again seeing as the mech and jockey wheels and shifter are still ok. after these 3 chains are used i may change to the afore mentioned 10 speed Zee set up, that Genesis reminded me of how much smoother that drive chain is!,

Sram X5  £75  cranks;
Budget £75 Sram X5 cranks have been ideal on the bike once i threw away the short lived Bottom Bracket that`s bearings are rubbish. replaced with a rebuild able Hope  BB- pricey at £75 plus £8 for the GPX-Hope/Shimano converter cups,  i now have the option of a cheaper complete £15 Shimano BB or source bearings for the Hope BB.

The cranks strip easy enough loosening the lock ring with a 10mm allen key until it is flush with no thread exposed, then loosen the 8mm bolt inside that locks against the lock ring and it pulls the crank off...



Bearings are a bit rough but will run em as they are rather than open them up now and risk contaminating them...


Off with the 26t `stealth` inner chain ring and a new Race Face 30t narrow wide chain ring fitted...

And fitted a small 22tooth `stealth` bail out inner ring even though i only used the previous 26 tooth once last year on the Capital Trail on 2 climbs, but it`s always there just in case!...


Crank axle was cleaned up and re greased and back on with the cranks and tighten up



Job done...


Halo 170mm through axle rear hub;


I like how the Halo free hub comes away simply by splitting the through axe with two 17mm spanners and the pawls are set in the hub,  no seal to fit or pawls and springs falling off the free hub if as often is the case your free hub is slightly stuck on...


As this one was despite copper grease  on the cassette before fitting, a small lever helps remove it...


Slight wear damage but nothing to worry about...


Re greased and don't forget the washer! then slip back on the hub body and refit the hub spacer to secure it...


New cassette on...




And back on the bike...




The chain was de greased having soaked in paraffin then cut to same length as the old chain before fitting.  I then washed the chain on the bike with the chain cleaner to remove any remaining paraffin  using TFR power washer soap (Traffic Film Remover).
Once dry the next morning i put the first of 3 coats of Squirt Dry lube on, it needs built up on a new clean chain...



Bail out stealth granny ring chain clearance is only 5mm in 1st but will be ok, It will go up the side of a house now in 22-42t ratio!...


Ready to go ride and have fun again!...


More soon...

Genesis Caribou Prototype; grows gears and off to new home


After only recently acquiring and build up the Prototype Caribou Fatbike frame set of UK Genesis bikes it`s off to a new home!, but no far away-my big brother was a bit gutted missing out on the nice new Pugsley i recently sold so this is going to him has put a big smile on his face :)


Why sell it?
Why sell it?, well i like living a minimalist lifestyle house wise and want to do the same with my bikes. I have also cleared a half dozen or so boxes of old spares tot he skips and it feels good to have less of things i don`t need. The old Surly Pugsley  and new Surly Wednesday are all i need with + wheels for both bikes, while the Dawes Ultra Galaxy and Pashley Speed 5 take care of tarmac and gravel (Old Railway line paths) duties...

Getting geared up...
Having built the bike as a single speed  i stuck some gears on it with a new 1x10 Group set comprising of a Race Face narrow wide 30t chainring, a Sunrace 40t cassette, and Shimano Zee mech and shifter...

Clear bash guard too!...


Easy Sunday Morning...
I thought i better get one last ride in on the bike and make a film with it and check the gears were bedded in ok, so up early and down to Tyninghame for 7am and had the coast to myself, perfect for some filming along some of the Secret Trail...




Into the woods and a lovely fresh air and smell after recent much needed rain, also the woods were alive with morning chorus bird song...


Secret trail...


Return on the rocks...


Film done and happy with the bike i took it home to clean it and prep it for handing it over to big bro today, he will enjoy this...


Wee film,

How to set up `Ghetto Split Tube` Tubeless - a short film...


A post for fellow bike nerds...

I have been riding Surly`s 29+ Rabbit Hole rim wheels for 4 years now on various Surly Pugsley builds and briefly on a Surly Karate Monkey 29er ,  Surly Krampus 29+, and Surly ECR 29+.
For 3 years now i have used them set up tubeless using the tried and tested method of using a split tube on the non tubeless specific rims.

Why use this method when you can buy tubeless specific rims and tyres by other companies?,
Well good point  unless your happy with your Rabbit Hole rims or other non tubeless specific  Fatbike rims you have but want an easy solution to getting no more pinch flats, better tyre sealant protection against Hawthorns (common around country roads here) and a more comfortable ride that a tubeless tyre gives,

This blog is not about what is better or the best way to do things, but a method i have found is fairly simple and lasts the length of the tyre life -barring no major rips in a tyre of course (fingers crossed ok there so far!).

It is a post on a method that can be done with out any big air hit contraptions or compressor,
But easily by your workshop floor pump or bike pump you carry when riding will do fine, so in other words it`s a set up that can be re inflated out in the field-so to speak...

There is also the ability to deflate and swap out a busted spoke or spoke nipple, something that can be common on an older wheel used on the coast with salt water exposure that rots spoke nipples.
Yes you could cut a hole in a proper tubeless tape and then patch it with Duct tape afterwards, but folk will often tell you who have done this of the tape glue breaking down over time and leaking sealant and air,

All methods of home made tubeless work or fail long term depending on the manufacturer of rim and tyre as well as how one goes about it. I have found the method i use to be reliable on all rims i have owned except Halo Tundra Fatbike rims where the tyre is just far to slack to try,

You can read a lengthy blog post i wrote on what has become known as `Ghetto Tubeless`  Here...

So a wee film just under 8 minutes, hope you can understand my SE Scottish accent if viewing from afar!  :)

29+ Commuting again...



After a week off from cycling after Forth Fat 17 and the following weeks cycling it was ace to get back on the Surly KramPug 29+ commuting again today...


And news is the drought is over (maybe) after heavy rain on Saturday and again on Monday.
It has transformed the countryside with a lush green growth you cannot help notice as you cycle country roads...




A day spent at work mowing as the sky cleared to a clear deep blue midday...


By 3pm the sky changed real quick as the forecasted rain swept in behind me as i rode home from work...


An approaching heavy shower had me turning off road and sheltered behind the wall of a WW2 roofless building on Station road south of Dirleton village...



No sign of it passing quickly i got the Alpkit waterproofs out the courier bag....



I gave it 5 mins before the rain lightened a bit and i continued...



Onwards into the tail end of the down pour and near Kingston i headed around Fenton Tower...





Baaa!



Onwards and south of NB Law into Balgone Estate and the sky once again cleared, time to get the waterproofs off!...




Some woodland trails before following the John Muir Way home...




All quiet and peaceful in `The Shire...`
