Good Evening,
1. I got a RockShox suspension pump. I didn't bother with sag but followed the chart for a 100mm travel suspension fork and a rider with gear of 80-90kg: 120 PSI, tops, so I put it there. It feels a bit funky; if anything, I'd like more air, but perhaps I'm not just tuned in to the suspension world. The RockShox pump is a gorgeous tool with an indicator with PSI and bar, and a button to release the air wich makes it all but a precision instrument. However, it remains just a pump, and it cost 499 SEK which is 54.36 USD - I barely dare ask, what the same item costs in the US? (499 SEK is 47.94 Euro or 42.80 GBP.) As for riding, I mostly note it when I brake with the front wheel, but sometimes it feels good, yes. 2. The shifters on the handlebars are still cold even with gloves. I put some gorilla tape [1] on the levers, as well as over the protruding bolts. With a nail clippers, this was an almost seamless fix. While it made sense in theory, I had a feeling it wouldn't make a difference in practice. But actually I think it did, just a little! 3. I examined the saddle from Syncros and found two M6 Allen bolts. Assuming 8.8 and no grease, the maximum safe torque is 10Nm [2] - however, here, they said 12-15! I put it to 13 which amounted to a small increment. 4. As an experiment, I increased the PSI in the front tire to 50 PSI (65 max) and the first thing that happened, when it was +/-0C, I made a right turn and flew over the bike. The chain, the H20-bottle, the rear light cover and the batteries flew off as well, otherwise it was undramatic. What I had before was ~35 PSI, and only Jehovah knows if that would have made a difference. The tires are 2.20. 5. I also got a CatEye Volt500XC lamp. If we disregard the annoying blinking modes, it has one mode of 500lm and one of 100. It is easy to place and remove from the handlebar; it is possible to rotate. The coolest thing is that is has a memory, so if you have it at 100lm, turn it off, and then turn it on, you don't have to cycle to get to 100lm again. The second coolest thing is that it is recharged with the common USB stuff that everyone has nowadays, so no hassle with batteries. This was also 499 SEK, BTW. On the ground, EB.

US$28.07 to US$269.95: https://www.amazon.com/RockShox-High.../dp/B07FTGR73R ? Do they come in different sizes? Is that really necessary? Do people typically do this is in a hurry? Mine seems fast enough despite its small size (protracted ~35cm). Mine doesn't seem to have a version number anywhere and I throw away the package. It goes to 300 PSI or 20 bar plus change, if that helps. -- underground experts united http://user.it.uu.se/~embe8573 |

It feels a bit funky; if anything, I'd like more air, but perhaps I'm not just tuned in to the suspension world. Careful, 120psi is often the upper limit. At least it is on my fork. Rear shocks are different, they have to be well above 200psi for serious offroad riding. You don't ever want to bottom out on those. I have, twice, and it is horrid. My fork runs at 110psi and that has never bottomed out.

My RockShox pump (red gauge) cost less half in the US and you can even get if for that price in Europe: https://www.bike-discount.de/en/buy/...ion-pump-33145 As for riding, I mostly note it when I brake with the front wheel, but sometimes it feels good, yes. It feels really good when the road turns into this, like here in town: http://analogconsultants.com/ng/bike/Chapparal1.JPG 2. The shifters on the handlebars are still cold even with gloves. I put some gorilla tape [1] on the levers, as well as over the protruding bolts. With a nail clippers, this was an almost seamless fix. While it made sense in theory, I had a feeling it wouldn't make a difference in practice. But actually I think it did, just a little! There is a product idea! Heated shifter levers :-) 3.

What I had before was ~35 PSI, and only Jehovah knows if that would have made a difference. The tires are 2.20. What did you do? Hit something? My MTB tires are kept between 55psi and 60psi. Rides a bit rougher than other bikes but no pinch flats and less rolling resistance. 5. I also got a CatEye Volt500XC lamp. If we disregard the annoying blinking modes, it has one mode of 500lm and one of 100. It is easy to place and remove from the handlebar; it is possible to rotate. The coolest thing is that is has a memory, so if you have it at 100lm, turn it off, and then turn it on, you don't have to cycle to get to 100lm again. The second coolest thing is that it is recharged with the common USB stuff that everyone has nowadays, so no hassle with batteries. This was also 499 SEK, BTW. Pricey. For me all those lights have a much too pointy beam. I prefer a MagicShine clone with an aftermarket diffusor lens which broadens the beam in the horizontal direction. Much better light, does not blind others and the cost including diffusor lens was under $20 per light. I have them on both the road bike and the MTB. On the ground, EB. "On the ground" usually has a bad meaning with cyclists, as in "involuntary dismount" :-) [...] -- Regards, Joerg http://www.analogconsultants.com/ |

According to the chart, one shouldn't exceed 205psi. So 120 should be fine. But... aren't you more likely to bottom out if you have *less* air in the chamber than more? I.e., more likely with 110 than 120? You have overpaid, big time. My RockShox pump (red gauge) cost less half in the US and you can even get if for that price in Europe: https://www.bike-discount.de/en/buy/...ion-pump-33145 Overpaid, no kidding! Yet I bought it in the one huge bike supermarket that exists here, off town, Sportson [1], not in some niche small shop in the city center. As for buying stuff online, I almost never do that altho I know it is less expensive that way. What did you do? Hit something? My MTB tires are kept between 55psi and 60psi. Rides a bit rougher than other bikes but no pinch flats and less rolling resistance. I made a normal right turn at a street intersection at a moderate speed. But it was +/-0C with freezing rain, so it was slippery. On the ground, EB.
