With that being the case, something like the Upstand here, would perhaps be your best option.
To your previous question about going from 25mm tyres to 32mm tyres, if the tyre is of the same compound(i.e. brand and model), then you should notice no loss of speed.
But if you go for a lesser quality compound of 32mm tyre, then you could definitely lose speed.

Sometimes the biggest challenge is finding the speedometer you want that is stocked and not outrageously priced.
The Cateye Strada Digital Wireless With Speed/Cadence Sensor should be widely available and would be considered a safe choice.
However I would be getting one of the below Sigma Computers, depending on what functions you value and I am assuming you would want a Cadence function.
Sigma Sport BC 23.16 STS - Cycle Computer wireless
Sigma Sport BC 14.16 STS CAD - Cycle Computer wireless incl. Cadence Transmitter
Sigma Sport BC 16.16 STS CAD - Cycle Computer wireless incl. Cadence Transmitter

The 300 is a very basic computer and I wasn't impressed on the one I used on a rented bike, it just seemed really cheaply made and for $50, it's not worth the price. I agree with Colonel that Cateye makes pretty good affordable computers, but some of their models and be a pain to set up and program, so do some research.

For a basic computer without cadence, I am using the Bontrager GoTime. It gets much better reviews, is easy to read, and is super basic. I put my phone in my under-seat bag with RidewithGPS and the GoTime on the handlebars. It's working out well.

My FX3 has a carbon seat post and an Allen head bolt. I hand tightened it, but I got to thinking -- should you use a torque wrench here? And if so, what's the setting for a seat post (or does that depend on the seat post?)

My Trek FX 1... With FX 3 parts... (Notice the carbon fork doesn't sit flush to the headtube)




Recently replaced the bottle cage to dual carbon bottle cages and Continental CX tires.

A couple weeks into using my New FX 7.2. Took her out to a a not so well kept rail trail this week and was impressed with how well it handled. Did about 25 miles or so and probably could have done a bit more. Going over some larger rocks wasnt fun but definitely wasnt painful.
Whats bothered me the most is the stock seat... thinking about replacing it. Any suggestions?

Wifey & two adult kids all have this saddle on their FXs. In fact the kids have been using it for years even before they wound up on adult sized bikes. I got them for them & just moved the saddles as their bikes changed. They never complain about saddle comfort. The reason I even ever found that saddle is cuz when I started commuting on a MTB I wanted a comfy saddle, tried it & liked it for my 34 miles round trip commute. But when I changed to a hybrid & converted it to drop bars I started having some comfort issues & chaffing so I switched to a road saddle & now have a leather brooks. But I've been thinking about getting one of these for one of my hybrids w straight bars, especially maybe the one I ride on dirt/gravel. It would be interesting to revisit it. I did ride it on my son's bike last fall on a long ride on his FX and found it to be comfy even on a long paved ride with a significant portion on gravel. sorry about the essay, but the short story is we have this saddle on several bikes for several ppl and we like it!
daughter has a black one

25 miles on an unpaved surface? very good! any pics of the trail? remember tires are part of the suspension system so tweaking them down a cpl psi might make that ride a skoosh more comfy. BTW that saddle is a twin to the Schwinn High-Density Foam Mountain Saddle which I usually find at Target or Sears for less that $20. found it on Amazon

just found a cpl old pics from when I 1st got that saddle. one pic shows the converted hybrid & the other shows the saddle on a red mountain bike I started with & a 2nd, the black version of the saddle my daughter wound up with, I had on a blue 70s road bike for a while. for short money, it's worth a try. today I put one on one of my current hybrids but wound up napping so never got out on it :/

Yes its a good idea to use a torque wrench on carbon parts, the torque spec should be inscribed on the seat post clamp right by the bolt, mine is full carbon and the max torque is 7nm.

Well, add me to the list
. I just got a black '18 FX3, 1st adult bike. I started getting interested in riding after we had our 2nd son 4 weeks ago. During my time off work I was using my wife's city bike with a child seat to take our 3 year old to daycare, tons of fun! I'm looking forward to riding/commuting to work and get a little more in shape with it.
Tons of stuff to learn on this threads!
