WT 42T cog mounted up…
I was curious how the Wolftooth 42T GC cog would work – particularly with the shortcage Shimano Zee derailleur on my Santa Cruz Nomad.
I gave it a shot and it works just fine. I’ve got dozens of successfully rides in so far.
Enough capacity to climb up onto the 42T cog…
I removed the 15T cog as I use the bigger cogs much more than the smaller ones. I was going to ditch the 13T cog, but it mates with the 11T cog to generate the correct spacing so I left it.
and take up the slack in the small cog…
What I used:
- 42T WT GC
- SRAM PG 1070 cassette
- SRAM chain PC 1031
- Shimano Zee derailleur and shifter
- Race Face 30T NW ring
- stock B tension screw [works fine]
- longer B tension screw that came with cog [works a bit better]
Wolftooth 42T GC cog before install…
The shifting is not as good as either a stock 10 spd or stock 11 speed setup, but it’s just fine. If you are a really picky shifting snob you may find it too clunky for your tastes, but if you are just happy that it shifts up and down reliably you’ll enjoy it.
Gratuitous SC Nomad shot…
Since I installed my 42T WT cog a few months ago they have come out with a couple new options:
- 40T cog for those that want a smaller jump at the low end
- 16T cog to allow for better shifting down in the smaller cogs
I haven’t tried either of these.
Light and supple tubeless road tires…
I’ve been running tubeless tires happily on my mountain bikes for a few years now. I’ve heard bits and bites about folks setting up road tires tubeless, but had not tried to convert any of my street tires to tubeless. I’m working on replacing my Surly LHT with a lighter more enjoyable commuter bike. I built up a set of 700c Velocity Blunt SL wheels with Hope hubs and ordered a set of Compass Bicycle Stampede Pass 32mm tires in the extra light flavour.
Velocity rims are not the easiest to setup tubeless – at least without using a rubber rim strip – and for this lightweight build I didn’t want to go that route. The Compass Bicycle tires are also not designed to be run tubeless so I was a bit worried this experiment might not work so well, but figured I had nothing to lose. If the setup failed I could just clean out the rims/tires and use tubes.
I went with a pretty basic methodology:
- 1 wrap Stan’s yellow tape
- Stan’s presta valve stem
- 1.5 scoops of Stan’s sealant
- 1 CO2 cartridge to seat beads
- shake wheels for a few minutes to distribute sealant
The tires seated well on the rims and although there were a few holes in them that needed sealing that resolved itself quickly. So far the tires are holding air with no noticeable lose after a few days. All in all it was fairly easy to set these tires up tubeless.
Surprisingly easy to setup…
I’ve got to finish the bike build this weekend and then I’ll test out the wheels to see how they perform on the road and report back in Part 2 of this post.
Vik’s 18″ Pugsley…
Update: Purple 16″ Pugsley is sold so only the 18″ green Pugsley is still available.
It’s come time to sell our beloved Surly Pugsley fatbikes. We love them, but our biking missions and lives have changed quite a lot since they were bought such that we don’t have any need for uber fat tires. They have been well taken care of over the time we have had them and were recently repainted and overhauled so they are like new. No damage, dents or other problems. They can be ridden as is for many more years without a major service.
These bikes are the perfect adventure rigs. They’ll take you over sand, snow and handle dirt quite well. They can be loaded up with soft bikepacking bags or racks and panniers. The steel frames give a comfortable ride and they are tough enough for anything that might come your way. The Alfine 8 IGHs have proven reliable and nearly maintenance free – ideal if you want to ride not worry about ripping off a derailleur or getting your shifting dialled in.
You can build 29+ wheels for these bikes using Surly Rabbit Hole rims if you want a less-fat option for summer time riding.
Spec’s Common to Both Pugsleys
- Surly Pugsley steel fatbikes
- Alfine 8 IGH with trigger shifters [geared 32T x 23T]
- Surly 135mm front hubs w/ 23T fixed gear cog attached for emergency wheel swap
- Phil Woods BBs [fresh bearings]
- Shimano cranks [Alivio/Deore] w/ some wear marks
- Avid BB7 brakes & levers w/ fresh housing and cables
- freshly powder coated frames and frame saver applied during rebuild
- offset 135mm rear end and fork
- no Surly stickers applied
- Both bikes come with a Salsa stem [I have some alternative stems to help you dial in fit]
- Both bikes come with a MTB riser bar [I have a few options we can discuss to dial in the fit]

Sharon’s Purple Pugsley…
Notes on Green [18"] Pugsley
- brand new Surly Rolling Darryl rims w/ cut outs [custom powder coated red]
- nearly new Big Fat Larry tires
- Epic Designs [aka Revelate] custom frame bag [like new]
Sharon in Baja…
- Green 18″ Pusgley $1350 + shipping
Purple 16″ Pugsley $1100 + shipping
$150 off if you buy both
We built these bikes up as a custom build from parts for ~$2500/each. The ideal was to have a robust no nonsense adventure bike and we succeeded in that regard. A new Pugsley costs close to $2000 and doesn’t come with an IGH which in my mind makes a ton of sense for a fatbike.
What’s not included?
- no saddes
- no pedals
- no racks
- no panniers or bikepacking bags [other than Epic Designs frame bag on 18" Pugs]
Vik’s Pugsley in Baja…
The 7 day trip I’m heading out on with some Dirt Hombres is similar to what is shown in these videos.
This map shows our base route…
We’ll fly from the yellow dot [Tyax Lodge] on the far right to the blue dot on the left [Lorna Lake] and then ride back to Tyax via the pink trails. If time allows we’ll explore a bit more in the area to the right of the green pen.
See you in a couple weeks. :)
Sorry it’s been so quiet on the blog lately. I’m getting ready for a trip to the Chilcotins and finishing off all the work tasks that are outstanding before I go.
On the plus side I’ll have some photos and a trip report for you in a couple weeks. Until then ride your bike and enjoy your summer. :)
