Re: Crank length thoughts.
After 4or5 sessions on the turbo and a ride out yesterday using the 50mm cranks and 38t oval chainring. I quite like it, but feels a bit under geared I'm going to try a 40t ring to see if it feels better or to fined out if it is just the shorter cranks and need longer to get used to them.

Re: Crank length thoughts.

Hi Mark,mark aldridge wrote: ↑2 Jan 2024, 3:26pm Hello Alan
Welcome to the can of worms!
I ride recumbent trikes and velomobiles with cranks from 155mm to 140mm.
On my uprights I used the industry standard of 175mm based on my height and leg length.
When I moved to my first recumbent trike it was a Windcheetah with a front fairing and needed 155mm cranks to give foot clearance. I was worried that this would have an effect on the power I could put down. No worries, I was spinning a fraction faster but no eurika moment. What was noticeable was there was less steering weave due to the lessening in distance my feet moved through. I installed 155mm cranks as they were available off the shelf.
I then started experimenting with cheap cranks cut down and went as low as 110mm. By trial and error I settled on 140mm as a happy medium.
All I can say is give it a try. As long as you have an axle with square ends you can try out a variety of short and kiddy cranks at minimal cost (they are easily sold on). When you settle on the right length for you then splash out on a lighter better quality set if you want to.
What you must remember is that within reason there is no "right" length and the human body is very accepting of a variety of parameters.
Good luck
Thanks for the push to shorter cranks, I've just ordered a pair of 150mm cranks and 38t oval ring from China. I'll let you know how I get on with them.
Alan.

Re: Crank length thoughts.
I seen that but I thought it was about bicycles and thought trikes would be different for some reason.

Crank length thoughts.
Happy new year to everyone.
I'm using 165mm cranks presently on my trikes, but thinking of going down to 160mm. I've only got short stubby legs, inseam of 30 inch. Any thoughts and advice would be appreciate it.

Re: Winter Trike Training (Wahoo Hub)
I use Elite rollers with the front roller taking off, it works fine. If your trike has bigger than 20'' front wheels than you should get away with not having to remove that.

Re: Kettwiesel Cross/Evo
It was just meant as a joke. I did look at Azub when I bought my last trike but thought they were to expensive, so I stuck with ICE and bought my second VTX.Grldtnr wrote: ↑5 Dec 2023, 6:44pmI disagree the Azub Tri -tris is a seriously good trike, I bought one sight unseen, after testing the usual suspects from ICE & Velotech.
I'd rather the bike tells me what is going on , over a false story with suspension.
Yes, the turning circle isn't that good, but then most Tadpole trikes are the same,but how tight does it get riding on the road?I say be a spendthrift, go down the pub and sup as many winter beers as you can!

Re: Kettwiesel Cross/Evo
You should forget about the Azub and save your money for the pub.

Re: 2 x 11 gearing
I run triples on both of my VTX's, Summer trike has FSA Carbon cranks 53/39 Rotor QX rings and a 30 round ring (only because I can't find a 30t oval ring to fit), Ultegra rear mech M/C, 11/32 cassette, Winter trike has Campag Athena triple 30/39/52 rings, Sram Rival L/C mech, 11/42 cassette, both have 11 speed Dura-Ace barend shifters and Athena triple front mechs. Both set ups work fine but takes a bit longer to get theme set up to achieve perfect shifting. I will never go back to compact chainset's after riding triple setups.

Re: Ice sprint tyre wear
Schwalbe Kojak's on the front and Continental GP on rear, on my VTX. A set of tyres will last for about 4000 mile at 85PSI.

Re: Stub (wheelchair style) hub wheels
I've got a pair of front ICE disc hubs. They are off a old VTX (the white one).
