Calculus Bikes

Hi Pieter, well done on your Epic result. We're glad you like the new dual and looking forward to getting one designed for you soon! CB

Now here we have some food for thought!

Would an engineering firm, that design custom bikes suffice?

Thanks for the advice. Will do!

We would like to give a formal apology: Terribly sorry for the inconvenience caused by the bike in question. We will try to be more considerate in future and focus more on soul-less mass production. Kind regards CB Team

FUN, and FAST racing.

Aah, all the compromises to get a fit. Fun reading all the suggestions though. My two pence of advice will be to clarify what you are going to use the bike for most and decide appropriate position and HANDLING (= frame size) accordingly.

Big ring, noted, thanks. Valves down not the most popular pose, but makes sense!!

Nice!

Hemel en Aarde bly maar mooi! Happy new year to all the Hubbers.

Or, do something really special and have a custom geometry frame build for you.

Hi Chris, thanks! Looking forward to doing the design for you. Cheers

Interesting comment on DS vs HT. What worked really well, and what other "features" you (anyone that rode) would have liked to have on their bikes to make the ride easier?

Amazing! Well done to EVERYONE from the very first to the final rider across the line.

Very Nice

Wow, Congrats where its due!

So, who is the local heroes going for top 10?

Glad his back on the "saddle"

We can do better than medium/medium! I'll send you a PM wrt price for a Ti Tandem with flat mount brakes. This will take the Ultimate Titanium Bike to the next level!

Good luck Kevin. Kit looks great, one of the best-kitted qhubeka bikes I have ever seen.

Three days to go!! The final countdown. Hope all the bodies and bikes are ready. How about some pics of the final setups?

Hi Odinson, The rider this frame was designed for is 175cm, so not very tall and riding the 120mm setup, due to the plushness of the 2.8" tires. Your comment on ST angle is very true though, especially when short chain stays are used on larger frames for taller riders.

Indeed, some more info: Official name: PMN 609m Geometry: With 120mm fork (compensated for sag) ETT: 609mm HT angle: 69 deg ST angle: 73 deg Geometry: With 150mm fork (compensated for sag) ETT: 609mm HT angle: 67.4 deg ST angle: 71.4 deg Stem: Casted Titanium 70mm Rims: cSixx Carbon 50mm ID Tires: 2.8" Rocket Rons Drivetrain: XT Seatpost: ISP, but can fit 31mm dropper Ride: Priceless

Anyone with some feedback or thoughts on this puppy?

Ditto. Inflation, inflation for what...R100 000 for everyone!
