New (bottom) vs old (top). Spotted this as new S-Works Power Saddle on eBay for half the price of a new one and pounced on it.

I was pretty happy with the power saddle already on the bike, this new one is the same width and full carbon so buying it was a bit of a no brainer.

Old saddle weight.

New one. Decent weight savings for sure!

I’ve decided to stop stalking new Canyon Aeroad’s and S-WORKS Tarmac SL8’s and instead go all out on my Allez Sprint.

The deep dish ENVE wheels I put on the bike made the bike look, feel and sound so much faster which has confirmed for me that the frame is awesome (and worth it!). As much as I like the concept of mechanical Shimano 105 being the groupset of the people, in reality it’s heavy and despite the Allez having semi-integrated cables the sight of the 4 cables around the stem was doing my head in so I thought I’d give electronic shifting a go.

I’ve decided to go 1x for weight savings (from removing the front derailleur and extra front chainring) and also for simplicity (less is more!) as well as attitude. I’ve chosen to go for an aero chainring too (it looks so damn hot!).

A 1x SRAM RED AXS E1 groupset is on order with CCACHE. I bought a Roval aero handlebar from Wooly’s Wheels, Tarmac SL7 stem direct from Specialized.com and the stem accessories (cable bat and cover + 3D printed spacer to adapt the SL7 to the Allez frame) from various online shops.

Updated specs below, final weight TBC!

Felt fucking naked!

So chuffed to have legend Tom Boorman of Hell on Wheels build the bike.

Couldn’t live with the zip ties so I installed some Jagwire alloy stick-on guides for a cleaner look.

Much cleaner!

Odd one out at the park.

Feels strange to not have any foot retention. I do have some Brotures straps ready to go so will get them on ASAP.

SO happy with how it turned out! Forgotten how awesome riding fixed is. What a fresh experience! Feels like riding a bike for the very first time!

Was love at first sight when I first spotted these sexy chainrings on a top-spec Dura Ace road bike. I love the almost topographical like patterns on the chainrings and aero cover. It took me a while to figure out what they were, turns out they’re made by a small company called Alugear who design and manufacture drivetrain components out of Poland.

Had to have them.

My 2022 Allez is running a Shimano 105 11-speed Shimano groupset and the only 11-speed kit they make is for Shimano Ultegra (the rest are for newer 12-speed drivetrains). Ultegra is gunmetal grey and I had to have these rings in black, so I was shit outta luck, but with a little research I found that 12-speed rings work with 11-speed chains, and so fuck it. I thought I’d do more research.

The 11-speed 105 crank spider is completely different to the 12-speed design, so to make the Alugear rings work I had to buy newer 12-speed 105 crank arms. I thought I might as well get even shorter crankarms (from 165 to 160) which will help the nasty toe-overlap I get on the Allez (I always replaced cranks to 165’s on my MTB’s in the past anyways as I like to spin a high cadence).

I spent hours figuring this all out. I really wanted to go for a 1x setup (less is more!), but that would mean having to upgrade to a much larger rear cassette if I still wanted to climb up hills. I do have a medium cage rear derailleur but the max rear cog would be a 34T which isn’t enough for climbing steeper hills (would probably need a 40T). I looked into getting a MTB or Gravel rear derailleur (GRX or XT) which would allow me to get an even bigger rear cassette and I also thought about running a much smaller front chainring (44T), but end of the day a small front chainring would look weak, and a huge rear cassette would not only add weight, it would look stupid on a road bike too.

As much as I wanted to rip the front derailleur off and go for a single 50T chainring up front logic kicked in. I don’t want to have to walk up steep hills with click clacky shoes on! I had to admit defeat in the end.

Even then, there were more options (mania? Yup I’ve got it!). I had an option to upgrade to Shimano Dura Ace cranks (as they’re also black) as Alugear make a kit for Dura Ace, but they were pretty damn expensive at $680, and they would defeat the purpose of going 105 in the first place. Turns out replacement 105 crank arms (without rings) at 160mm length aren’t in stock anywhere in the country (plenty on AliExpress but rather than risk getting fake shit) so I ended up buying a full 105 12-speed crankset (with rings) as they were only $200, and instead of going for a 1x drivetrain I settled for a 2x Alugear AERO kit for 105 12-speed.

End of the day I still get the look I was after, save a little weight and I still retain the small front chainring for climbing steep hills, and if I ever do man up to go 1x I’d already have the new cranks and AERO cover so I’d only have to order a 1x Alugear chainring.

A fixie with brakes. Too afraid to go 1x because of hills. FFS I’m getting soft in my old age.

Tom’s shrine.

Motomags!

So stoked to reconnect with BMX legend Tom Boorman of Hell on Wheels. As much as I’d love to build the Dosnoventa fixie myself I’m getting Tom to build it. Honestly couldn’t think of a better guy for the job. She’s in good hands!
