Anything wrong with 100 PSI in 700x32 tires on a road bike?

The Trek Domane SL7 comes with wide, modern rims with 25mm internal width. Using 32mm wide tyres at 100 PSI (6.9 bar) should be perfectly safe with such rims. As you note, the tyres are also rated for ...

Which part(s) has the greatest slope of price per pound(kg)?

The full answer is long and complicated but the short answer is almost surely 1) the proper air pressure at zero cost (meaning, zero slope in terms of price/kg); followed by 2) latex tubes (at a ...

Trek procaliber eating cassettes

The highest/hardest gear is 10T which is not a lot of teeth-chain contact. If you're riding home with a very dirty bike that could grind into the 4~5 teeth that are meshed with your chain. If so, ...

Cyclocross bike as a touring bike

The Crossrip line isn't quite a cyclocross bike; its designed somewhere between a commuter bike and a cyclocross bike (more relaxed and heavier than most cyclocross bikes; also, rack+fender mounts). ...

Should I use a Trek Domane SL5 for touring?

People tour on all kinds of bikes. That said, if you're going to tour on the Domane, you'll need to figure out how you'll be carrying your gear, since (as Argenti mentions in his comment), it doesn't ...

If you are pretty much exclusively using the 10t sprocket I’m not very surprised that it’s only lasting 320km in a mountainbike context with lots of dirt and sand. Bigger sprockets last much longer. I ...

Should I use a Trek Domane SL5 for touring?

Regarding durability, I'm sure the Trek Domane SL5 2021 can take a bit of a battering, but I personally would be wary of taking anything with a carbon frame on a tour. I did a 3.5 week tour of Japan ...

Can I use SRAM DUB Red Crankset in a Trek Madone SLR 7 that requires GXP?

Modern cranksets either have 24mm-ish width spindles, or 30mm-ish spindles. DUB (28.99mm spindle) falls into the latter category. GXP spindles (24mm, tapered to 22mm on one side) fall into the former. ...

Anything wrong with 100 PSI in 700x32 tires on a road bike?

There are a few points here, that need to be cleared up: The air volume is greater for 700x32, so I believe the additional volume will cushion more than e.g. 700x26 This is wrong. The slimmer your ...

Trek Madone SLR Di2

Possibly the bike has a cassette size that the Dura-Ace Di2 rear derailleur does not support. The current DA RD-R9150 (short cage) rear derailleur has a max low sprocket size of 30 teeth whereas the ...

Problem with cassette and derailleur

You can't use an 8 speed shifter with a 10 speed cassette. The space between individual cogs is smaller than on an 8 speed cassette. The shifter moves the derailleur a fixed distance per shift, so it ...

Chips in carbon frame - how worried should I be?

These appear to be paint chips in areas of the bike where rock strikes are common. I don't see any evidence of delamination--a separation of the carbon fiber weave and thus carbon fiber damage. ...

Chips in carbon frame - how worried should I be?

I agree with Jeff that you are most likely looking at paint chips. The thing to look for in surface damage is torn fibers. To recap, carbon fiber is made from sheets of carbon fiber that are ...

Are old bikes good bikes?

The only thing we can say for sure is that a bike from 2005 is not necessarily bad just because of its age. Good and advanced bicycle technology was already available back then. Unlike 1905 or 1955. ...

I often rant against 1× drive trains for how unsatisfactory they are for road+MTB use, and particularly those 10-teeth sprockets are simply a bit rubbish. But they're definitely not that bad either. ...

How do I convert a 24-speed bike to a seven speed?

I cannot imagine a good reason to do this. Your drivetrain will not be more robust. Doing this will be fairly expensive. You'll need a new cassette (to go from 8 gears to 7) and new a new rear shifter ...

Restoring an old Trek 820 with a modern groupset
