Rocker plates
Hi everyone, I (70 yrs young now) ride around 5–6 hours per week on a Kickr Bike, mainly following a structured training plan on Rouvy. Outdoors I usually do fun rides between 30 and 100 km, and after a professional bike fit (IBFI-certified studio), I have no real comfort issues there. My indoor setup is adjusted to match my gravel bike, but after about an hour of training, I start to feel some discomfort—mostly in my hands. To help reduce the effects of static positioning, I’ve just ordered a rocker plate (still waiting for it to arrive). Has anyone here used a rocker plate, and if so, what’s been your experience? Did it make a noticeable difference in comfort or realism during longer indoor sessions?

@Daniel Ward has one for his indoor set up. everyone I know that has experienced comfort issues in doors has managed to solve them by using a rocker so hopefully you will too. might also be worth checking if the bikes level including saddle, hand discomfort suggests excessive weight through the front of the bike. that said could simply be a case of you not making the micro adjustments and movements you naturally make when riding outdoors

Bike Fit Setups
There are a number of bike fit ‘tools/systems’ used by bike fitters, what is the best?
0 likes • 3h
in my experience as the 'client', the use of software has decreased in the last 10 years or so (the exception is saddle pressure mapping). It clearly exists still but bike fitters seem to use to check their work rather than setting a bike and rider up to meet the parameters set by the software. I suspect the most widely used is still Retul given the head start in the market. I don't like it though, fixing a wired sensor that can fall off feels seriously out of date. I'm willing to bet the more modern, higher rate video capture systems are better for the fitter too.

Do I need new cleats?
New shoes with new cleats fitted by Dan in July. From my ride yesterday I’ve now got significant rubbing on both crank arms. I’ve attached videos to show how much internal rotation there is and a photo of the cleats. Thanks in advance for your help.

@Luke Bell not used Look cleats for a long long time, these don't look too bad unless I'm missing something obvious. seems strange that both sides have gone at the same time whether it's the cleats or the pedals. Not sure if it's just the video but you don't seem to have 'float' outward and the internal looks greater than 4.5 degrees. are the pedal bearings alright?

🎥 Webinars - what works best for you?
We’ll be running live webinars in this community, covering Bike Fit concepts and common themes that come up here. To help plan these properly, it’d be really useful to know: - Which days/times of the week out of the options below suit you best? Also let us know by commenting below, if you're more likely to join us live, or catch up on the recording at a later time? No commitments of course, this is just to help shape things in a way that works for most people. Let us know if you have any other suggestions around timing of the webinars. Thanks in advance for your input.

Top of foot pain
After many years road cycling with a 4mm shim I started with top of foot pain after trying a new pair of cycling shoes (Lake CX 238 - old shoes Shimano R320). I have a (sports podiatrist) confirmed tibia length difference of around 15mm. I increased to a 6mm shim (back on my old shoes) and the pain has subsided somewhat but is still there (old & new shoes). I have done a Shimano Dynamics bike fit and the recommendation is to move to 170mm cranks (from 172,5 - I used to use 175mm), use a wider saddle (155mm from 142mm) and move my saddle forward. The other things I probably could consider are to increase the shim to say 8mm and / or a pedal adapter to widen my stance (Q-factor?) on my short leg. Any feedback or suggestions would be greatly welcome

@Neil Harper Hi Neil, if all was relatively comfortable with the old shoes then I would start there. Were you measured for the Lakes? Sorry if I’m telling you something you know already but the soles (Lake call them ‘lasts’) can be quite different in terms of volume and support between models so you potentially have a completely different type of shoe I’m not sure if its advisable to adjust the Q factor with spacers on a single side but regardless, I’d advise one change at a time as part of a process of elimination and adaptation
