DAMN KNEES

 Remember? The Top Fuel needed a 170mm dropper, measured with 175mm cranks? 

And going to 180s meant what? I needed to drop the post 5mm.

Remember how much I could drop the post?

not even 1mm

way way back

knee pain from saddle too high (sub patellar tendon to be specific) 

May be time to rebuild the post on the Stache and move it to the Top Fuel and swap the 170 over to where i can drop it low enough to keep that pedal distance correct. 


So keeping track: cranks smaller than 180 and my right side of my lower back gets so fucked I can't stand up in the morning or put pant or anything on my legs/feet w/o sitting down. 

Seat height higher than that certain number (1000mm) and my knees complain. 

Pretty tolerant of everything else.

Also I killed the cadence battery in the Wahoo. I wonder if there's a cumulative statistic with the head unit. Because how ever many hours I have on it, that's how long the battery lasts in the foot pod. 

AND i rode the stache to work.

nothing like a bit of frustrating high cadence work.

So

slow

But last night I dosed up the sealant and put a new chain on (all bling bling SS 1speed one) and got the chain length set for the 22T cog. Will need to slide the dropouts back when I switch to that gear but all i gotta do is hang the chain and that 20mm socket is kind of super nice. now i can actually torque it properly. 

The other thing I remember about this particular knee issue, it takes a while to resolve. Esp if I keep pedaling. 

Need to find a shim or swap posts before riding the Top Fuel. But that's okay - i think I've gotta stick with the Stache until after Great Glen.

y'all be good

You can just buy the Garmin XC power pedals. The stack is nearly +5mm over SPDs, problem solved!

Going to shorter cranks/higher saddle took some getting used to, but overall I wish I'd done it a long time ago. But old habits die hard...

Yeah that would certainly fix it but man I smash the XT pedals on shit every other ride or two sometimes every ride.

That would be expensive I think, can't imagine the Garmin ones are going to shrug that level of abuse off the way the shimanos are.

I had hopes that I could manage with the slightly taller seat height. Guess not.

I was thinking that too. I don't recall ever seeing a saddle "stack height" mentioned in specs but they can't all be the same. You could shim your cleats too, but that would mess up your other bikes. Maybe try one of those old skool sheepskin covers to get a bit more height...

Like a lot of people, I thought the Garmin pedals were nice except for the price. The durability is of course a concern. But the stack difference would be a huge hassle unless you could put them on all your bikes. I don't see moving pedals from bike to bike as practical.

I'm running XT/XTR trail pedals on the road now. Not sure how they would work in a crit compared to Speedplays, but it's just easier to run one type of pedal shoe for everything, especially with the type of riding I do these days. Shimano was rumored to be working on a power pedal, which would be cool. Although I use a Garmin 130 right now, and that doesn't record left/right balance anyway. I know my left leg was around 5% under my right, but it would be interesting to see if it's got any better since I made changes.

I need LESS height on the Top Fuel. AKA the dropper to be a 165mm instead of 170. Or a 150. But I bought the 170 because it was the ONLY one I could get at a reasonable price (employee purchase).

The Stache has a 120mm dropper but more importantly there is 75mm between the bottom of the seatpost collar and the frame. There's zero mm between the dropper collar and the top of the frame on the Top Fuel.

And in reality I don't need the full 170 on the top fuel but it could make the Stache more playful (aka dirt jumper)...

I'm some variation of SPD pedal on all the bikes. Same pair of shoes for everything since 2017 (well I do wear those winter boots a handful of times a year -shit those would be perfect).

THere we have it Dave. I'm wearing the Wolvhammer boots when I'm riding the Top Fuel now.

Problem solved.

Yeah you're right, I have it backward on the saddle. A "low stack" saddle should be a little easier to come up with. Vise and a sledgehammer...

I have Shimano winter shoes and yes, the saddle feels too low with them. It's hard to measure exactly how much.

Have you seen the SRM/Look cranks with adjustable length? They have an eccentric insert the pedal screws into. Seems a little sketchy, likely to creak. Only goes 170-175.

I think you might do well to adapt to 175 though. It might take some time and a little PT, but in the end you might feel some benefits. I was stuck on 175 forever and you could not change my mind, but now that I was forced to switch to 170, they just feel better. Can't say I'm not going slower though...
