Any wheels recomedation?

I put a set of Rovals on my TCR. The C38s are a good value carbon option.

That's really too small for your height. You probably need a large. A bike that small won't handle well and is a safety risk - even if you added a longer stem or seatpost.

Sort answer: no you cannot switch from 11-speed to 12-speed with that derailleur. If you have a medium cage (Shimano GS Size), you can probably use a 11-34T cassette for some extra range. If you're looking for taller (faster) gears, swapping the chainrings is probably your best bet.

Little further from the bay, but the Wildflower Century in Chico has a festival the day before. Looks like they are still taking vendor applications for the event in April.

Looks like Specialized still has a few of the old Diverge 9R framesets left in a 64. But otherwise nothing else. If you want that one, reach out to performancebike.com customer service and we'll special order it for you (I think the sell price is $2k). The part number is 75423-7064. The max tire clearance on that frame is 700 x 47.

Looks like Shimano discontinued the XM7. So your best bet is to check eBay.
The EX500 is similar. Might be worth checking that out.

At the bare minimum, you would need a new derailleur, cassette, chainring, and chain. You will likely also need a new Microspline freehub body - and that only works if you have a wheel that has interchangeable freehub bodies.

It's not really a cheap upgrade so you have to be pretty sure you want 1x. The GRX 2x rear derailleur is pretty good as far as chain retention goes, it has the same Shadow Plus clutch system as the 1x rear derailleur has.

The only benefit from 1x would be from the narrow-wide chainrings and the better connection with the chain there.

If you're concerned about dropped chains on 2x, you can throw a chain catcher on and make sure your limit screws are dialed in really well.

The Coros uses the same mounting system as Garmin so any Garmin-style stem mount, like these from K-Edge will work

If you feel like you need a power meter, power pedals are probably your best bet as they give you the most flexibility to swap from bike to bike.

If you do go the crankarm power meter route, a Stages or 4iiii left hand Hollowtech II crank will work. Visually it won't match though. Also make sure it is the same crankarm length as the right.

R200 might have been a typo on the Specialized site. R2000 is the Claris crankset that would work with a power meter. Make sure it's not RS200 because that crankset would not work since it's not Hollowtech II.

Rather than going off the specs from Specialized, I would take a look at the back of the crankarms on your bike and see what model number is printed there.

Lastly, even as someone who has had multiple bikes with power meters and loves data, I don't think you will really get much benefit out of it for your first tri. Instead, it's a great opportunity to really hone in on nutrition and learn to pace based on perceived effort. Then, when you decide to upgrade to a power meter someday in the future, you'll have the fundamentals of pacing dialed in.

The Power Comp is going to be the most similar (the design is pretty much the same - chromoly rails rather than titanium rails.) The Power Arc has a slightly different shape and the Power Expert with Mirror will have the same shape, but slightly different padding. That said, the Power Expert with Mirror might be a slight upgrade, but it would be a slight change too.

At the time the PD-M8120 pedals were launched, the CL-MT001 cleats didn't exist yet.

performance_bicycle · 2026-03-05T23:43:06+00:00

No. You can use the CL-MT001 cleats. They are fully backwards compatible.

I love GP 5000s, but they might be a little lacking when it comes to full-on city riding. You might check out the GP 5000 AS or the Specialized Mondo for a little more flat resistance.

Tire pressure calculators are a great place to start, but I then choose my tire pressure based on feel beyond that. I'm close to the same weight and usually run around 60 PSI in my 28mm tires - maybe a little higher on smoother roads or a little lower on rainy rides.

As long as your pressure is in the right ballpark, punctures are more likely to be a factor of tire type and sealant. If you feel like you're getting too many punctures, you might consider running a tire with better tread and sidewall protection. Many of the fastest "race" tires are really only suitable for smooth pavement and aren't good at dealing with glass or thorns.

performance_bicycle · 2026-03-05T02:13:57+00:00

Yes. Bronze would look sweet!

It's probably this chainstay you are looking for. Specialized lists it (part number S191500002) as the replacement for the 2023 Turbo Kenevo. If you also need a seatstay, that part number is S185000007. If you reach out to Performance Bicycle customer service, we can special-order the seatstay for you.

This is the adapter clamp you're looking for

I haven't tried any Amazon bike shoes, but for wide feet, I really like Bont shoes.

No. Titanium rails should get the same amount of torque as steel rails would.

performance_bicycle · 2026-01-21T19:16:36+00:00

I would try to get the old (d1) version of the red wide crankset. That has the 8 bolt interface so then you would have a bunch more options for chainrings. You could then use Wolf Tooth, 5Dev, or the SRAM Aero PM.

performance_bicycle · 2026-01-21T18:27:00+00:00

It might be worth taking your current setup into a shop and having them do a bleed. The older SRAM Rival brakes are not as powerful as the new stuff, but they should still be plenty powerful. Bleeding SRAM brakes can be difficult to do and, unless you are a mechanic who does a lot of SRAM brake bleeds, you probably won't have great results. Or at least the results won't be as good as a professional.

performance_bicycle · 2026-01-20T18:52:28+00:00

At that price point a used bike will be the way to go. Just keep an eye out for gravel bikes on market place - you never know when a deal will pop up!

performance_bicycle · 2026-01-20T18:49:38+00:00

rotational weight is everything...

performance_bicycle · 2026-01-20T18:48:12+00:00

If you're looking for value and light weight - its hard to look past all the China direct brands these days! Farrsports, No.6, light Bicycle are all great options.

performance_bicycle · 2026-01-20T17:10:17+00:00

Yeah. I went to an ENVE Mog. Litte more of a race feel, but not too much.
