    Influence of Sponsored Riders

    I watch reviews but I am not influenced by anyone sponsored by a specific brand or frightened to speak out on things they did not like. I am mostly interested in how they rate the way the bike rides. After that I am guided more by function than form...........ie I value good engineering and...

    Levo Gen 3 Problem with rear brake sram code rs

    that would make more sense in terms of the issue you have............if the diaphragm was prevented from expanding by water between it and the cover the pressure in the lever would then push the calliper pistons back. Your issue is definitely with the lever so at least removing the reservoir...

    Levo Gen 3 Problem with rear brake sram code rs

    ...so the diaphragm in the lever is broken. It is a sealed system. The diaphragm is there to enable the volume of fluid to expand as it gets hot without impacting on brake pressure............the tiny hole in the diaphragm cover enable the pocket of air a bove the diaphragm to be at normal...

    Levo Gen 3 Upgrade from CODE RS to RSC?

    S= swing link ( less lever throw than direct link) Both Code RS and RSC have it. C= contact (bite) point adjustment...........Code RSC only. As a bove Code RSC uses pivot bearings rather than bushings for the lever. Dont underestimate the contact point adjustment function especially if like me...

    Levo Gen 3 Target Sag %

    I think it more likely to need different SAG in the fork to the shock, possibly determined by the weight balance of the bike with the rider in the ready position and the stroke of the fork compared to the shock ............ but also to check to see if the bike feels balanced front to back when...

    Rail (750Wh) Bosch Smart V5 update Mileage/Speed error

    From what has been reported a bove today it seems the only element of the speed sensor operation left ( ie its not the magnet or the sensor) is the calculator method used in the motor firmware. That method is probably different for the Rim Magnet/ motor sensor arrangement.........at least as far...

    Levo Gen 3 Problem with rear brake sram code rs

    ...same...been using one for a couple of years now so cleaning and lubing the pistons on the rear calliper is part of my routine everytime I do a mini service.

    Levo Gen 3 Problem with rear brake sram code rs

    So the brake block pushes the pistons back flush with the calliper ....unlike the brake pads which together are not as wide. It therefore ususally takes a few pumps on the lever to position the pistons closer to the pads. The pistons only move out and back a short distance.......the amount they...

    All New 2023 Orbea Wild

    E vol is "extra volume" nothing to do with E bike specific tuning.

    Levo Gen 3 Problem with rear brake sram code rs

    did you set the lever at the correct distance from the centre of the bars before bleeding? Tip of lever 80mm from centre of the bars. That sets the position of the piston in the lever reservoir. You also have air and too much fluid in the lever syringe. The fluid should be soild from the...

    Michelin E-Wild separated bead

    fyi.............I have used the Wild Enduro ( not the E Wild)....no problems with them. I dont like 2.6 anyway, I always find them a bit vague. The front tyre especially has very large and aggressive corner knobs so I wonder if the larger (2.6) volume tyre just cannot take the strain on the bead?

    Rail (750Wh) 2022 Bosch Smart 750 Trek Rail Thread

    The Bosch CX Performance motor is Gen4...........and has been for quite a while. I think Bosch refer to the Smart System as their Gen 3 system..............., Gen 2 was the previous Bosch system using the Purion/original Kiox as controller.........there is no Gen4 system!! But Trek seem to have...

    LED Remote - switching assistance level

    the LED Remote slides left and right on its mount. If it is slid as far left as its mount allows the bulk of it fits over the clamp for the dropper.

    Trek Rail - Carbon Frame Crash Damage

    The UDH is supposed to be able to move back on impact and the 25 nm torque is designed to determine the degree of force necessary to do that. The UDH is supposed to have a limit in terms of how far it can rotate backwards dictated by a stop on chainstay.......thereafter the UDH should break...

    Levo Gen 3 Cadence and Assist

    my experience of the Brose motor was that 50 to 60 cadence was fine and rarely needed or benefited from 70 to 90. Unlike the Bosch motor which definitely works best with a higher cadence, Spesh seem to dial in a broader effective cadence range. In terms of punching up tech climbs, gear selection...

    Whyte E-506 Creaking

    Sounds like maybe a case of motor angst? ( what you most fear going wrong!). Most creaks come from the saddle or headset/ stem, but can also be cranks or pedals. As a bove, first step is to differentiate between riding in the saddle and riding up on the pedals.

    Different fork axle to crown

    Are you referring to the Trance E +3? If so the Suntour Fork was 150mm travel ( 140mm Fox DPS shock) and head angle 64.6 not 64 so not sure what has changed unless the new fork has a different offset to the Suntour.
