Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

SRM Origin

Anyone has it? How is the charging port in the rain conditions? Seems kind of exposed.

Thanks!

Do some research on headunits too - SRM doesn’t work with all brands. My crank doesn’t work with my Wahoo Bolt. Wahoo is aware of this and has been working on a fix. SRM wants you to use their headunit/computer.

Should have been more explicit. I currently have their PC7 with older wirless dura ace. I plan to get PC8, and debating on origin. Will sell my current one before it gets too obsolete.

I have the origin on my bikes. The unit doesn’t have a charging port. The cable has two prongs at the end being held in place by magnetic force. I have one on my rain bike and have not had a problem.

I have issues with the Bolt and my Origin also. I don’t think they plan to fix the problem. I made them aware of my problem in May. It works fine with my Garmin.

Ah so yours without rechargeable battery? What made you decide to go that route?

I do have the rechargeable battery. It doesn’t use a port like a phone has. It is two prong cable held in place by magnets so the unit is completely sealed.

Ah I see. Thanks. Well bought origin from ebay. Should arrive soon. Will see how those connectors stand up to weather. Will probably put electrical tape over it. Just in case.
Meanwhile last week bought PC8, also from ebay. Really like it. Nice crisp screen, and I can customize the fields. Really like that I can have NP on my main screen, and zone bar provides motivation.

One thing unlike my PC7, PC8 doesn't report battery status of my current Dura Ace SRM. Not a big deal since I am getting origin, but still. The amount SRM charges for these things you would think they would get their **** together with support. Which in general blows.

The PC8 will let you know when your SRM battery is getting low. A warning screen will pop up. At least mine did, with the PM7 versions of the SRM (pre-origin).

Ah. With PC7 and PM7 it would show hours left every time I downloaded data. I guess warning is better then nothing, but step backwards.
On the other hand I was riding today with teammate with Quark in the rain. His PM started showing wrong power numbers. He had to cut the ride short. Mine been rock solid for the last 5 something years. Will see how Origin holds up. Received it on Friday. Will install next week. Got some M3 clear tape. Going to apply to cranks to keep them pretty. haha

He cut his ride short because his power meter stopped working?

Well he didn't want any more water penetration and potentially permanently screwing it.

Hmm. What's the proper way to remove tri lobe? Tried pushing it out by hand, but no luck. :/

Do you have 24 or 30 axle?
I tried to install it on my bike with 24 version, same as my old SRM, and it got stuck. Took it to a shop and they said axle is 1mm too wide. This is super strange. Pretty sure axle width is standard. Maybe mine is defective or something?

I have a 24. It should have come with rubber spacers to take up space. I put mine on Trek products.

Hmm. Directions don't say anything about spacers... How long/width is yours 134mm?
There are spacers in a box, but they are for 30mm one. Grrr. Maybe because guy I bought it from bought 30mm originally. Then ordered 24mm one after.
Do spacers go on both sides, or just the drive side?

I had the bike shop install it. They gave me these spacers back when I picked up the bike and said I didn’t need them. They do mention them also in the installation instructions. Remember them mentioned about what to do if there was play in the installation.
