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). FWIW, I do know people who have used the Crossrip for light touring and a day to day basis and were happy. But if you'll be happy is a highly personal decision. ...

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 have any mounting points for racks. There are workarounds for mounting a rack (which come with compromises), and increasingly people are bikepacking—using frame ...

No, Trek will not sell you just the frame if they don't offer it in their product lineup. And a bike shop wouldn't either, given that they have to buy the whole bike anyway. It's just a massive headache to allow things like that for manufacturers. And many manufacturers generally aren't all too keen on letting people sell their bikes online (accessories are ...

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 myself last year (best time of my life!) and no joke, I smashed one of the seat-stays into a bicycle gate thing between Osaka and Kyoto on my first day of riding....

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. Almost all press fit bottom bracket shells can take cranks with 30mm or similar spindles. Trek’s BB90 bottom bracket standard appears to be an exception. That ...

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 Ultegra RD-R8050-GS (medium cage) will take up to a 34. If you have an 11-32 or 11-34 cassette, you do in fact need the Ultegra GS derailleur. SS and SG ...

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 can't reach the position of the cogs if they are not spaced as intended. The fact that you can use the 4 biggest and the smallest gear is pure luck, because the ...

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. However, no amount of photo inspection can replace a hands on one. Were I to purchase a carbon fiber second hand, I would have a second opinion of the carbon fiber ...

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 impregnated with resin. The structure is cured in a mold at high temperature and pressure. You need the fibers to be torn for the structure to be compromised. Damage to ...

I have used a Surly Cross Check for touring and it worked fine, for short tours (2 nights) with just rear panniers up to 3 weeks with front and rear panniers, mostly on dirt roads and some rough trails. While it is ostensibly a cyclocross bike, it does have a bunch of features suited to touring compared to a more modern high performance cx bike (e.g. steel ...

Many things on bicycles are consumable and anything that moves or rubs is going to have to be replaced, it's just a matter of when. It's unusual for a cassette to wear out completely within a year although if it's been ridden on a stretched chain or without regular cleaning and lubing it'll wear out much faster. In my experience chains are normally the first ...

It is ok to have different width of tires on front and rear wheels, I have a thinner tire on rear wheel as the clearance is low and I wanted to fit a full fender. Why would someone have different wheels? - It is quite uncommon for new bikes to have different width of tires but used bikes can(as your's is). Perhaps, if the wheel was damaged/stolen the ...

You don't have to spend $2K on a bike that will be faster, lighter, easier to ride and generally better than your 25 year old bike. (I'm assuming the US here as you used mentioned dollars). That said, if the old bike only needs minimal maintenance that will not be expensive to do so, get it into a satisfactory condition and ride it for a few months. If you ...

Just keep riding what you have, especially if it fits. Getting out to ride is the most important thing, a new bike won’t change that. As you ride more and determine the type of riding you enjoy most, then you will have a better idea of your exact needs and can decide if a new bike makes sense So at this point, since I haven't found any super compelling ...

The liquid in the top photo is hydraulic fluid. You probably unscrewed the bleed port screw at some point and now your system has less fluid than it needs and also air. Seek a tutorial using your preferred search engine "bleed tektro brakes" on how to bleed your brakes and follow it. When you have done that you need to check two more things. There's ...

I though about it long and hard and consulted a friend who works for yeti in manufacturing. Figured there is some margin for manufacturing tolerance and factor of safety. Filing worked like a charm. Wet sanded and polished the cut afterwards and it looks great. I figured the only real worry at that spot on the caliper is structural support in case of a ...

The braze-ons beneath the down tube are traditionally for mounting a third bottle cage. Of course that bottle is more exposed to road dirt than the others, so many people use it for various utility purposes. (You can get water-bottle-shaped repair kits that will fit in there, batteries, air reservoirs for air horns and I'm sure other things as well.) It ...

Assuming that you own the 2012 model, your bottom bracket should be a Shimano M171, according to the Trek Archives. Found a Shimano Technical document that says you should have a 68mm thread width.

Crank arm looks like it is actually fully on the tapered part of the axle. Square taper cranks don't mate up to the frame bottom bracket shell, there's supposed to be a gap there. See: Sheldon Brown's page on square taper cranks/bottom brackets. The gap does look a bit large to me though. Are you replacing crank arms? (Crank arm in pic looks new.) Is there ...

Shimano prides itself on seamless shifting and it's specs are quite conservative to preserve that reputation. With a little sensible caution and a chain catcher you should be able to replace the 26 with a 22. 22/36 is a big drop. If you are just going to replace a single chainring, I'd suggest a 24 rather than 22. When cogs are that small, even 2 teeth is a ...

First, don't ride the bike if one of the brakes is not working properly. Not working well can change to not working at all and put you in a dangerous situation. Take the bike back to the store where you bought it, a 2 month old bike with a major brake problem should be fixed under warranty. In any case if you do not have experience diagnosing and repairing ...

This answer stems from comments on @Max's answer: if you intend to only do structured workouts, then if you can find a gear where there's no chain rub, you can set the trainer to erg mode. In erg mode, the trainer automatically adjusts its resistance. You don't need to shift. In practice, even on erg mode workouts, I do find myself shifting when I need to ...

Several manufacturers, (Apidura being just one) make top tube bags that use a bolt on mount. Some use a shouldered screw for the mount. This mates to a keyhole shaped holes in the bag frame. It slips on and locks into position. You can search for bolt-on top tube bags to find a model that fits tour needs.

Crankarms and pedals are sold in pairs. Once in a while you can get lucky finding a person selling a single, but don't count on it. We can't currently see how much damage has been done. A shop would be more reluctant to warranty their work inserting helicoils (if they do it at all) than installing new, known-good parts. I suspect this is at least as much ...

Yes they will as I just did it. I contacted trek support and asked for the part number for the 2017 crossrip frame set. Then went to local bike shop and they purchased it for me. Now looking forward to the build

Here's the Shimano datasheet. So we know it's a square taper, ISO-threaded BB. So a UN54/UN55 is the replacement part (take the UN55). 73 is the shell size: 73mm. 113 is the spindle length: 113mm.

http://www.trekbikes.com/us/en/support/faq/question/what_are_the_differences_between_all_the_materials_you_use_in_your_frames/ This link might be helpful. It describes only two grades of alloy for their current bikes. The higher grade being hydroformed. Hydroforming allows profiling and shaping of the tubes. Its comparative to blow moulding. With respect ...

It sounds like they compare very directly with other manufacturers who list the alloy and butting, except that Trek doesn't release that. My guess is that some of those descriptions actually overlap and are just marketing hype that changes every couple of years. Your best bet would probably be to contact Trek directly and and see if they will "translate" ...

Mino is a link that changes the geometry of the bike. High lifts the BB (about 10mm) and steepens the head tube (1/2 degree) compared to low. With the link set low the bike will be more stable but less agile, especially on down hills. With it high it will be more agile but less stable, with lower chance of pedal strike (due BB height). The difference is ...
