What's your inseam? Just curious.

How well does it climb steep hills compared to your 170mm? Did you need an adaption period. If you had comparative power numbers, that would also be very informative.

Thanks. I could'nt quite figure which of the listed apps matching that name actually takes into account the crank length. :rolleyes: However , I found out that the good old Sheldon Brown's Bicycle Gear Caclulator has it all! :cool:. https://www.sheldonbrown.com/gear-calc.html Gain Ratios is...

Thanks for the link! Great info there!

I think, if the leg speed remains the same, then the shorter the crank the higher the cadence. So, to compensate for the increased cadence, for the same power, the chainring has to get smaller. But it is not clear by how much. (Probably there is a good gear calculator online that we need to...

Is there an adaptation period? When I first moved from 170mm cranks to just 165mm(stock S40 cranks), it felt a bit harder to push (naturally becuase the leverage is reduced) but it took a while to get used to it. Climbing did not improve, despite the noticeable increased cadence (that new...

I prefer MTB SPD (two bolt cleats) becuase I can move them further back easily to my midfoot by custom drilling my shoes. I had road cleats (3-bolt plastic cleats) in the past but they are difficult to customize for midfoot and they wear out much faster. However they were much wider and which...

I occasionally get on my DF for a change. The power translates quite closely to my S40 but is a touch higher on the DF. I noted the following: 1. The DF is noticeably lighter than my S40 ( by more than 3.5Kg). It is therefore more responsive to accelerations. 2. I climb faster on the DF ...

For my case, (a 2019 S40) they also had started cracking but I inserted some 4 washers ( one for each bolt, between the clamps and the chainstay) that I got some from an old road bike stem. I tightened them using a torque wrench to I think about 4Nm if I remember corrrectly. It has stayed put...

Well, you know , that tiny 10-tooth sprocket cannot fit a standard shimano HG free hub. It's just the way it is. :) You have to change to either a Micro-Spline or an XD-SRAM hub. No other way . But the 10-36 cassettes are readily available, just not for HG hubs.

Now just try a 11-42 wide range 11-speed cassette (46T x 11-42) and it will pretty much replace the 50/34 x 11-28 system. You may just need to use a derailluer hanger extender https://www.aliexpress.com/item/1005006397636360.html

Another local TT in Nairobi. I improved from my previous performance. Got a fourth in the masters category! S40 is pretty capable. Check out my activity on Strava: https://strava.app.link/SoX0q8sytHb

The Goldix with a chromoly axle? Great!

For those interested in these short cranks and need an affordable spider based power meter to match, they can combine these with something like these 3bolt Xcadey ones: All in all, they can make for a good budget option: https://www.aliexpress.com/item/4000126830286.html

Since they are less than $50 each, one can experiment and test them. Here is one more variation: https://www.aliexpress.com/item/1005006362951568.html

Maybe something with a steel/chromoly axle is safer. These ones by Goldix are even better! They are HollowTechII compatible. https://www.aliexpress.com/item/1005006391100185.html "GOLDIX Children Bicycle Crankset 110mm/127mm/140mm/150mm/155mm/160mm Crank" BB68 M68-73(standard), suitable for the...

For those interested in affordable short cranks that are not custom made, here are some Chinese ones. Only about $45 without the chainrings. Interestingly enough, they are branded "Cruzbike" hahaha! :) CRUZbike Road Bike Crankset 155/160/165/170/175mm Bicycle Crank 9/10/11/12 Speed Chainring...

Interesting new (and hopefully) more affordable Wireless Groupset from WheelTop. A SRAM alternative. https://wheeltop.com/products/eds-bicycle-derailleur

My S40 has become search a pleasure to ride. On the first day I covered about 160Km at 30.9 Km/h and I was not even tired! I felt like the bike was just gliding through the air, smooth as butter! Most of my friends had saddle sores at the end of the trip while all I had was minor glute fatigue.

Thanks! I documented my custom tailbag here: https://forum.cruzbike.com/threads/affordable-aero-tailbags.15296/
